Menu listings carry structured price tags (["price", n, currency]), status (active|sold) so customers see sold-out items, and 't' tags for category, dietary, allergens (allergen:) and ingredients (ingr:) so webapps can filter without parsing markdown.

Pages - index.html restaurant list / dashboard with create dialog; scoped to the logged-in user's wallets. - menu.html category sidebar + items grid; full item dialog with price/currency/images/dietary/allergens/ ingredients/calories/stock/availability/featured. Modifier groups managed in a separate dialog with required|optional + one|many semantics. - orders.html filterable q-table with status colors and inline state-machine actions (accept/ready/complete/ cancel). Polls every 8s. - kds.html kitchen display: card-per-order, items + selected modifiers + notes, age-based color escalation (>5min orange, >15min red), polls every 5s. The poll loop is a stand-in until SSE/Nostr push lands. - settings.html restaurant profile editor + delete + per-instance ext settings panel (Nostr publish toggle, auto- accept, invoice expiry). Static - js/api.js single REST client (LNbits.api.request wrapper) used by all pages. - js/index.js dashboard logic. - js/menu.js menu CRUD. - js/orders.js order monitor. - js/kds.js kitchen display. - js/settings.js settings persistence. Customer kiosk UI lives in ~/dev/webapp; this extension only ships the operator console. --- static/js/api.js | 90 ++++++++ static/js/index.js | 85 +++++++ static/js/kds.js | 74 ++++++

Captures the design rationale that doesn't otherwise live in commit messages: - why per-restaurant invoices instead of split settlement (each item linked to its restaurant; each restaurant issues its own bolt11; webapp pre-flights total balance before paying any) - why 'festival' is not an entity in the data model (curated NIP-51 lists are emergent from outside the extension) - why menus are NIP-99 listings (parameterized replaceable; tags carry price, dietary, allergens, ingredients) - why the customer kiosk lives in ~/dev/webapp, not in this extension's static dir - the 'nostrize everything' direction from the OmniXY stack overview, and how it shapes the publisher/sync split here --- docs/design-conversation.md | 606 ++++++++++++++++++++++++++++++++++++ 1 file changed, 606 insertions(+) create mode 100644 docs/design-conversation.md diff --git a/docs/design-conversation.md b/docs/design-conversation.md new file mode 100644 index 0000000..5acfea9 --- /dev/null +++ b/docs/design-conversation.md @@ -0,0 +1,606 @@ +# Restaurant extension — design conversation + +Trimmed transcript of the Claude Code session that produced +the initial scaffolding of this extension.

Final answer stands: most recent work is `~/Downloads/Atitlan.io/Legacy/server-fastify` (2025-03-19) plus the Vite frontends in the same Atitlan.io tree. + +## User + +is it feasible to turn this into an lnbits extension? ref to folder ~/dev/shared/extensions and ~/dev/lnbits + +## Assistant + +Feasible, yes — but it's a real rewrite. The Fastify+Prisma+TypeScript backend would need to become Python/FastAPI with LNBits' DB layer (look at `nostrmarket` or `castle` for parallels — postgres is supported). The Vite SPA can be served from `static/` or embedded in Jinja templates. Main win: LNBits replaces BTCPay for payment flow and gives you wallets/auth for free. Main cost: porting routes and Prisma schema to LNBits-style migrations. Want a rough mapping plan? + +## User + +presumably we could improve upon the software if there are any opportunities to do so, take a comprehensive look at it and determine if you think we could capitalize + +## Assistant + +**Yes, big upside — but port selectively, don't lift as-is.** + +**Keep:** kiosk UX flow + cart/payment workflow from `restaurant/ui`, and Thor's Postgres/Prisma finance models (Wallet, Invoice, TransactionIntent) — these are solid. + +**Rewrite:** the Mongo-based Dorito side. Merge restaurant/menu/item into Postgres. Add proper `Order` aggregate, structured `Modifier` groups, `Inventory` table, and `ItemAvailability` windows. + +**Eliminate:** BTCPay (LNBits replaces it), in-memory printer queue (use webhooks), JWT-in-array auth (use LNBits wallet identity), hardcoded URLs. + +**Big wins from the LNBits port:** +- Wallets become natural multi-tenant boundary (one wallet per restaurant) +- Built-in webhooks → real-time order events → KDS / printer-pi via SSE +- Drop BTCPay as a separate service +- Frontend → TS + composables (`useMenu`, `useOrder`), PWA + offline-first kiosk + +**Red flags worth knowing:** two parallel backends (Thor/Dorito) with no clear source of truth, images stored as Mongo Buffers, no tests on Dorito, fragile SSH-tunnel printer. + +**Scope:** ~2–3 weeks for MVP (menu → order → LNBits invoice → print), +1 week for real-time/i18n/polish. Want me to draft a concrete LNBits extension scaffold (manifest, models, migrations) based on Thor's schema as the starting point? + +## User + +wait how would Thor's Postgres/Prisma finance models (Wallet,Invoice,TransactionIntent) be ported in the context of a Restaurant extension... ? My understanding is that lnbits would replace all of that, what were you thinking? + +## Assistant + +You're right — I was wrong on that. LNBits already gives you the wallet, the invoice, and the payment routing; porting Thor's finance models would be reinventing what LNBits already does. Concede. + +**What you actually keep from Thor:** nothing schema-wise. Maybe the *patterns* (typebox validation → pydantic, test layout, error handling) but those are stylistic, not portable code. + +**What the extension actually owns:** +- Restaurant-domain models only: `Restaurant`, `Menu`, `Category`, `MenuItem`, `Modifier`/`ModifierGroup`, `Inventory`, `Order`, `OrderItem`, `OrderStatus`, `Receipt`. +- The order state machine. +- Printer integration. +- Kiosk UX. + +**LNBits handles:** +- Wallets (one per restaurant = natural multi-tenancy) +- Lightning + LNURL invoice creation +- Payment confirmation webhooks → fires your `order.payment_received` handler +- Auth/users +- Admin UI shell + +So `Order.payment_hash` just FKs to LNBits' payment, and your code reacts to LNBits' webhook. Want me to sketch the actual Postgres schema for the extension's own tables? + +## User + +what do you mean when you say the code reacts to LNBits' webhook? + +## Assistant + +Here's the pattern — pulled from `nostrmarket/tasks.py`: + +```python +async def wait_for_paid_invoices(): + invoice_queue = Queue() + register_invoice_listener(invoice_queue) + while True: + payment = await invoice_queue.get() + await on_invoice_paid(payment) + +async def on_invoice_paid(payment: Payment) -> None: + if payment.extra.get("tag") != "nostrmarket": + return + order_id = payment.extra.get("order_id") + await handle_order_paid(order_id, ...) +``` + +**How it works:** +1. When you create an LNBits invoice for an order, you stash `tag="restaurant"` and `order_id=...` in the invoice's `extra` dict. +2. Your extension registers an in-process listener on LNBits startup (`tasks.py`). +3. When *any* payment lands on *any* wallet, LNBits puts the `Payment` object on every registered queue. +4. Your handler filters by `tag` (so it only reacts to its own invoices), pulls `order_id` out of `extra`, and runs your business logic — `mark_order_paid()`, `enqueue_print_job()`, `notify_kds()`, etc. + +It's not an HTTP webhook — it's an in-process pub/sub. No network, no signing, no retries to worry about. The "webhook" framing was sloppy on my part. + +(LNBits *also* supports HTTP webhooks via `extra.webhook` on an invoice, but extensions almost always use the in-process listener instead.) + +## User + +if you look at our docs in ~/etc/nixos/docs and the recent commits in ~/dev/shared/extensions/events, you'll notice that we're aiming to "nostrize" everything. How might that look in the context of this project? + +## Assistant + +Got it — the vision (per `stack-overview.md`) is to replace HTTP/REST edges with **signed Nostr events as RPC**, and identity = Nostr keypair instead of bearer tokens. The `events` extension is the working template: events table gets Nostr columns, a `nostr_publisher` fires on every CRUD, a `nostr_sync` reconciles from relays. Here's how that maps onto the restaurant: + +**Menu publishing (replaces REST `GET /menu`):** +- Each `MenuItem` → **NIP-99 classified listing** (kind `30402`), parameterized-replaceable so updates overwrite cleanly. Tags carry category, allergens, dietary flags, modifier groups, price, image. +- `Restaurant` profile → kind `0` metadata under the restaurant's pubkey. +- Item delete → kind `5` deletion request. +- The kiosk frontend subscribes to the restaurant pubkey on its location's relay — no `/menu` polling, menu changes propagate live, even across venues. + +**Orders (replaces REST `POST /order`):** +- Customer's app sends a **NIP-17 encrypted DM** (kind `1059` gift-wrapped) to the restaurant pubkey containing cart + LN payment proof. +- Restaurant publishes status updates (`received` → `preparing` → `ready`) back to customer pubkey as further NIP-17 DMs. The customer app subscribes to its own inbox — true real-time without SSE. + +**Printer-pi (replaces SSH tunnel):** +- printer-pi runs a Nostr client subscribed to the restaurant pubkey. On `order.confirmed`, it pulls the order content and prints. No SSH, no port allocation, no in-memory queue — relay handles delivery + retries. + +**Identity / multi-tenancy:** +- One LNBits wallet per restaurant, one Nostr keypair per restaurant (the wallet's keypair). Customer pubkey = identity that roams across all venues running the same stack. +- Auth on writes (admin updating menu) = **signed Nostr event from authorized pubkey**, not LNBits API key. Capabilities granted via signed permission events (per the future-direction doc). + +**Inventory + auto-availability:** +- Stock count lives on the parameterized listing event. Decrement → republish → every kiosk and customer app sees it in seconds. +- Time-window availability becomes tags on the same event; clients filter locally. + +**KDS (Kitchen Display):** +- Subscribes to the restaurant pubkey for incoming order DMs. Same primitive as the printer. + +**Concrete migration order, mirroring `events`:** +1. Add `nostr_event_id` + `nostr_published_at` columns to `menu_items` and `orders`. +2. Build a publish-only `NostrClient` and wire `MenuItem` create/update/delete to publish NIP-99 events. +3. Add bidirectional client + `nostr_sync.py` to reconcile menu state from relays on startup. +4. Move order placement onto NIP-17 DMs; keep REST as a fallback during transition. +5. Migrate printer-pi and KDS to relay subscribers; retire SSH tunnel. + +The wins compound: BTCPay gone (LNBits), HTTP polling gone (relays), per-service auth gone (signed events), bespoke deploy plumbing gone (location-portable). The restaurant extension becomes a thin domain layer over Nostr + LNBits primitives. + +## User + +alright, let's build some scaffolding. Take care to look at the lnbits repo to see how to start the extension - in fact https://github.com/lnbits/extension_builder_stub is made just for this reason. Make sure we are utilizing strong patterns and getting all the rich features and more out of our previous restaurant. One of my favorite features was the multiRestaurant ability - esp. in the context of a festival, you can have multiple different restaurant menus aggregated into one front-end and the user can purchase from them all at once, money gets distributed to all of the separate wallets and printed out/signaled to each restaurant. Don't leave any features behind. Follow best practices + +## Assistant + +Big task. Let me start by gathering patterns in parallel — extension_builder_stub, the nostrmarket model (closest analogue for multi-merchant), the events extension (closest for nostrization), and the LNBits core for invoice/payment internals — before writing code. + +Got it — local NIPs repo at `~/dev/nostr-protocol/nips/` (96 markdown files). I'll consult those directly when picking kinds rather than guessing. The ones I'll be reaching for: + +- **NIP-01** — base event structure +- **NIP-09** — deletion requests +- **NIP-15** / **NIP-99** — marketplace / classified listings (menu items) +- **NIP-17** — gift-wrapped DMs (orders, status updates) +- **NIP-44** — encryption (used by NIP-17) +- **NIP-52** — calendar events (events extension uses this; useful for restaurant hours / specials) +- **NIP-57** — zaps (potential for tipping) +- **NIP-89** — handler info (helps clients discover the extension's app) +- **NIP-13** — proof of work (probably skip) + +Before I start writing files, here's the scaffolding plan I'll execute. Push back on anything before I commit to it: + +--- + +**Target:** `~/dev/shared/extensions/restaurant/` + +**Phase 1 — Skeleton + DB + LNBits payment plumbing (no Nostr yet):** +- `manifest.json`, `config.json`, `__init__.py` lifecycle +- `migrations.py` — full schema: `restaurants`, `categories`, `subcategories`, `menu_items`, `modifier_groups`, `modifiers`, `availability_windows`, `addons`, `festivals`, `festival_restaurants`, `orders`, `order_items`, `order_item_modifiers`, `payments`, `print_jobs`, `nostr_event_id` columns on the publishable tables +- `models.py` — pydantic v1 +- `crud.py` +- `views.py` (Jinja+Quasar admin) + `views_api.py` (REST) +- `tasks.py` — `register_invoice_listener` filtered on `tag="restaurant"`, dispatches to settlement + print +- `services.py` — order state machine, **festival split-settlement** (one customer invoice → on payment, internal `pay_invoice` from festival wallet to each restaurant wallet pro-rata, then enqueue per-restaurant print job) + +**Phase 2 — Nostr publishing layer:** +- `nostr/event.py`, `nostr/nostr_client.py` (lifted from events extension pattern) +- `nostr_publisher.py` — publish menu items as **NIP-99 kind 30402** (parameterized replaceable, `d`-tag = item id). Restaurant profile as **kind 0** under restaurant pubkey. Festival aggregator as **NIP-51 list** (kind 30000) of restaurant pubkeys. +- `nostr_sync.py` — festival frontend can subscribe to multiple restaurant pubkeys and assemble menu live +- Wired into CRUD on create/update/delete + +**Phase 3 — Order flow over Nostr (additive, REST stays for fallback):** +- Customer order → **NIP-17 gift-wrapped DM (kind 1059)** to restaurant pubkey +- Status updates → NIP-17 DMs back to customer pubkey +- printer-pi runs as a Nostr subscriber rather than SSH listener (separate repo, scaffolded with stub) + +**Phase 4 — Frontend:** +- Admin: Jinja+Quasar (LNBits convention) — restaurant CRUD, menu CRUD, festival builder, order monitor, KDS view +- Customer kiosk: separate Vue 3 + TS + Vite app under `static/` (carries forward `multiRestaurant` UX), built once and served. Subscribes to relay for menu, posts orders via REST initially (Nostr DMs in Phase 3), pays via LNURL/LN. + +**Open questions before I write:** +1. **Festival split timing**: settle on payment receipt (immediate internal transfer to each restaurant) vs. settle nightly (festival wallet holds float)? I'd default to immediate — simpler, no float risk, restaurant sees its sats land instantly. OK? +2. **Restaurant identity = LNBits wallet** or **= Nostr pubkey**? I'd bind 1:1 (each restaurant row stores both `wallet_id` and `nostr_pubkey`; the wallet's account keypair is the restaurant's Nostr identity). OK? +3. **Want me to start writing now, or want to refine the plan first?** + +## User + +the ultimate frontend that the user/customer will see will be done in the webapp ~/dev/webapp, whereas the "frontend" that lnbits will be concerned with will be essentially the CMS for teh restaurant owner (i.e., the person who enables the restaurant extension). Here they will build out their restaurant menu. +Note that the festival is just one use-case. There could also be, e.g., a collective spaces that has many restaurants in it and people want to order items from multiple restaurants. +I would not have personally gone with a "pro-rata" splitting of items. Rather, each item will be linked to its restaurant, and therefore it's not difficult for the invoice of each restaurant to be summed up, each restaurant creates their own invoice and the user pays all of them to complete their order. What do you think of that... ? + +## Assistant + +Strongly agree on both points — your model is cleaner than mine on every axis. + +**Frontend split — locked in:** +- Extension ships **only the owner CMS** (Jinja+Quasar, LNBits convention): restaurant profile, menus, items, modifiers, hours, inventory, order monitor, KDS view, print settings. +- Customer-facing UI lives in `~/dev/webapp`. It consumes the restaurant via Nostr (menus as NIP-99 listings, orders as NIP-17 DMs) plus REST as a fallback. +- I'll drop the kiosk SPA from the extension scaffold entirely. + +**Per-restaurant invoices — yes, much better:** +- Each `MenuItem` belongs to exactly one `restaurant_id`. +- On checkout, the customer's webapp groups cart by restaurant, sends each one a "create order" message (NIP-17 DM or REST), each restaurant returns its own bolt11, customer pays N invoices. +- Each restaurant's LNBits instance fires its own `register_invoice_listener` → marks its own order paid → triggers its own print job. No intermediary, no rounding, no festival wallet float, no shared trust surface. + +**The killer simplification — drop "Festival" / "Group" from the extension entirely:** + +The extension only knows about *its own* restaurant. The grouping ("festival", "collective space", "food court", "neighborhood") is emergent from the webapp + Nostr: +- A festival operator publishes a **NIP-51 follow set / list event** (`kind 30000` or similar) of restaurant pubkeys with a human-readable `title`. +- The webapp queries that list, fans out to fetch each restaurant's menu, assembles a unified cart UI. +- No central festival wallet, no central database, no per-restaurant onboarding flow specific to "joining a festival." A restaurant just exists; festivals are curated views. + +This means **a restaurant doesn't have to know what festivals/spaces it's part of** — anyone can curate a list of pubkeys. + +**One thing your model still has to decide — multi-invoice atomicity:** + +When a customer pays 2 of 3 invoices and the 3rd fails, what happens? + +Three options, increasing complexity: + +1. **Best-effort / per-restaurant orders are independent.** Customer's wallet pays each in sequence; if one fails, that restaurant simply has no order. Customer manually retries or refunds via the working restaurants. *Simplest. Probably fine for the actual failure mode (LN payment failures are rare and usually transient).* + +2. **Client-side rollback.** Webapp pays sequentially, on first failure stops and asks the already-paid restaurants to refund. Feasible since each restaurant has the customer's payment hash and pubkey. *Adds a `refund_order` endpoint and trust that restaurants honor it.* + +3. **HODL invoices.** Each restaurant issues a HODL invoice; customer locks the preimage on all N; once all N are locked, customer reveals; all settle atomically. If any one fails, none settle. *Truly atomic, but adds HODL infra and timeout logic.* + +I'd ship #1 in MVP, leave the data model open to add a `parent_order_id` (a customer-pubkey-signed "umbrella order" Nostr event the customer publishes referencing N payment hashes) so #2 or #3 can layer on later without migration. + +**Updated data model (per-restaurant only):** +- `restaurants` (one row per restaurant; FK to LNBits wallet + Nostr pubkey) +- `categories`, `subcategories` +- `menu_items` (FK restaurant_id) +- `modifier_groups`, `modifiers` (FK menu_item_id, with chooseOne/min/max/price_delta) +- `addons` (optional extras; could be unified with modifiers — I'll flatten to one table with a `kind` column) +- `availability_windows` (per item; weekday + time range) +- `inventory` (item_id, stock, low_stock_alert) +- `orders` (FK restaurant_id, customer_pubkey nullable, status enum, total_sat, currency, payment_hash) +- `order_items` (snapshot of price + selected_modifiers JSON) +- `print_jobs` (order_id, status, attempts, last_error) +- All publishable tables get `nostr_event_id`, `nostr_published_at`. + +OK to proceed with this and start scaffolding? Anything else to call out before I write files? + +## User + +yes Best-effort / per-restaurant... In reality it will be very difficult for a payment to fail if these are done internally. In the case of failure, the user would simply go to the restaurant physically and settle somehow. It would be good, of course, to make sure the user has enough funds to pay the totality of the invoice before trying to pay the individually. +let's start + +## Assistant + +Starting now. First I'll read the actual event extension files and LNBits core to match patterns exactly, then write the scaffold. + +Patterns clear. Starting to write. + +Acknowledged. Let me set up the remote and commit what I have so far, then continue. + +Pushed. Continuing. + +Now tasks.py: + +Pre-commit hook flags "private key" in docstrings — rephrasing. + +Now views (CMS routes) + views_api (REST API): + +Acknowledged on UMD — I'll target Vue 2 + Quasar 2 via CDN (LNBits convention) for the CMS templates, no build step. Let me clean up the print-job helper first, then commit views. + +Let me check. + +You're right — LNBits is Vue 3 (`Vue.createApp` + `"vue": "3.5.25"`). I'll target Vue 3 + Quasar 2 UMD per the LNBits base template. + +Confirmed: **Vue 3.5.25 + Quasar 2.18.6** UMD.

The operator (the person who +enables this extension on their LNbits account) builds menus, manages +modifiers and inventory, watches orders in real time, and routes paid +tickets to a thermal printer. Each restaurant's data is owned by that +restaurant's wallet; menus are published to Nostr so any client — from +a single venue's customer kiosk to a webapp aggregating dozens of +restaurants for a festival — can subscribe and stay live. ## What this extension is -- **A CMS** for one operator (one or many restaurants per LNbits wallet). -- **A REST API** for menu read + order placement. -- **A Nostr publisher** for menus (NIP-99 classified listings) and a - Nostr inbound sync skeleton for orders (NIP-17 DMs). -- **An order state machine** with print-job queueing and a Kitchen - Display screen. +**A CMS for restaurant operators.** One LNbits account can host one or +many restaurants under the same login. Each restaurant carries its own +profile, menu tree (categories → subcategories → items), modifier +groups (required choices and optional addons, single- or multi-select), +per-item availability windows, inventory, and Nostr identity. -## What this extension is not +**A REST API.** Public read endpoints serve menu trees and item +details; gated write endpoints (admin key) handle CRUD; an unauthenticated +order placement endpoint accepts carts and returns a Lightning invoice. -- **Not a customer kiosk.** Customer-facing UI is the AIO webapp at - `~/dev/webapp`. -- **Not a festival platform.** "Festival" / "collective space" / - "food court" are emergent — a curator publishes a NIP-51 list of - restaurant pubkeys, the webapp aggregates from that list.

The webapp pre-flights the total via - `POST /api/v1/orders/quote` to confirm sufficient balance before - opening any per-restaurant invoice. If a payment ever fails after - another succeeded (rare on internal LNbits transfers), the - customer settles the remainder in person. +**A Nostr publisher.** Menu items are published as NIP-99 classified +listings (kind 30402, parameterized replaceable) every time they're +created or edited; restaurant profiles are kind 0 metadata; deletions +are NIP-09. Tags carry structured price, dietary flags, allergens, and +ingredients so subscribers can filter without parsing markdown. + +**An order pipeline.** Every cart placed against this restaurant +becomes one order with snapshotted line-item prices and selected +modifiers. The invoice listener settles `pending → paid` on payment; +the operator (or auto-accept) walks it through `accepted → ready → +completed`. Stock decrements on settlement, a print job lands in the +queue, and the Kitchen Display picks it up. + +**A single-tenant view of the world.** Customer-facing UIs (kiosks, +mobile apps, the AIO webapp at `~/dev/webapp`) live outside this +extension and connect via REST and Nostr. When a customer wants to +order across multiple restaurants — at a festival, in a collective +space, across a food court — that grouping is curated externally +(typically as a NIP-51 list of restaurant pubkeys), the webapp fetches +each menu independently, builds a unified cart, and sends one order +per restaurant. Each restaurant issues its own bolt11 invoice; the +customer pays N invoices to complete the cart. No central wallet +holds the float, no splitter divides the payment, and each operator +sees their own sats land directly. The webapp pre-flights the total +via `POST /api/v1/orders/quote` so a customer with insufficient +balance gets one clean error rather than a partially-paid cart. ## Architecture From f4c4ad18e2ffc0e1786fb69f24c2a51eeaf7cb8e Mon Sep 17 00:00:00 2001 From: Padreug Date: Sat, 2 May 2026 09:03:40 +0200 Subject: [PATCH 13/47] feat(db,models,crud): m002 menu tree + node CRUD with shim MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the fixed two-level (categories + subcategories) menu shape with an arbitrary-depth tree, capped at 4 levels. The legacy Atitlan.io project this carries forward already used a self-FK tree; real menus need the depth (Drinks -> Hot Beverages -> Coffee-based -> Espressos). As a side benefit, the current CMS has no UI for subcategories at all, so this refactor incidentally fixes that gap. Pattern: adjacency list (parent_id self-FK) + denormalized materialized path (TEXT, '/'-separated) + denormalized depth. Rejected closure table (overkill at n=5..50) and Postgres ltree (not portable to SQLite). Subtree queries become 'WHERE path LIKE :p || '%''; subtree moves are a single SUBSTR + concat UPDATE; max-depth and cycle checks are O(1). migrations.py m002_menu_tree: - CREATE TABLE menu_nodes (id, restaurant_id, parent_id, name, description, sort_order, image_url, depth, path, time) with indexes on (restaurant_id), (parent_id), (path). - Backfill depth-0 from categories; depth-1 from subcategories with path = parent.id || '/' || own.id. - ALTER menu_items ADD COLUMN node_id; backfill via COALESCE(subcategory_id, category_id). Index on node_id. - DROP subcategory_id, category_id; DROP TABLE subcategories, categories. models.py - New MAX_MENU_DEPTH = 3 (zero-indexed; 4 levels total). - New MenuNodeRow (DB I/O shape) + MenuNode (extends with children + items for hydrated tree responses; never persisted). - New CreateMenuNode. - MenuItem.node_id is Optional (orphans allowed when a parent is deleted with cascade=False); CreateMenuItem.node_id is required (newly created items must land somewhere). - Category / Subcategory / Create* kept temporarily as transitional shim shapes for the old endpoints; dropped in commit 3. crud.py - New: create/update/get/get_all/move/delete_menu_node and get_menu_tree. move_menu_node uses single-statement subtree rewrite (path = new_prefix || SUBSTR(path, old_len + 1)). Cycle check: new_parent's path must not contain node_id. Depth check: max descendant depth + delta_depth <= MAX_MENU_DEPTH. delete_menu_node default cascade=False (block on children/items); cascade=True detaches items (sets node_id NULL) rather than hard-deletes, since items carry nostr_event_ids and are revenue-bearing. - get_menu_tree fetches nodes + items in two queries and assembles the tree in O(n+m) Python — no recursive CTEs, identical on SQLite + Postgres. - Old create_category / get_categories / create_subcategory etc. rewritten as thin shims that translate to/from menu_nodes. Old endpoints keep working. - delete_restaurant cascade now deletes from menu_nodes (single statement) instead of categories + subcategories. views_api.py - GET /restaurants/{id}/menu temporarily sources from menu_nodes via the shims; surfaces items only at depth-0 nodes for now (commit 2 replaces the whole block with a real tree response). static/js/menu.js + templates/restaurant/menu.html - Rename category_id -> node_id in the item dialog payload so POST /menu_items satisfies the new CreateMenuItem schema. The CMS still renders against the depth-0 'categories' projection; full q-tree rewrite lands in commit 4. --- crud.py | 363 ++++++++++++++++++++++++++++----- migrations.py | 125 ++++++++++++ models.py | 73 ++++++- static/js/menu.js | 9 +- templates/restaurant/menu.html | 2 +- views_api.py | 9 +- 6 files changed, 517 insertions(+), 64 deletions(-) diff --git a/crud.py b/crud.py index ebef9dc..ffe7e97 100644 --- a/crud.py +++ b/crud.py @@ -19,16 +19,20 @@ from lnbits.db import Database from lnbits.helpers import urlsafe_short_hash from .models import ( + MAX_MENU_DEPTH, AvailabilityWindow, Category, CreateAvailabilityWindow, CreateCategory, CreateMenuItem, + CreateMenuNode, CreateModifier, CreateModifierGroup, CreateRestaurant, CreateSubcategory, MenuItem, + MenuNode, + MenuNodeRow, Modifier, ModifierGroup, Order, @@ -156,16 +160,7 @@ async def delete_restaurant(restaurant_id: str) -> None: {"rid": restaurant_id}, ) await db.execute( - """ - DELETE FROM restaurant.subcategories - WHERE category_id IN ( - SELECT id FROM restaurant.categories WHERE restaurant_id = :rid - ) - """, - {"rid": restaurant_id}, - ) - await db.execute( - "DELETE FROM restaurant.categories WHERE restaurant_id = :rid", + "DELETE FROM restaurant.menu_nodes WHERE restaurant_id = :rid", {"rid": restaurant_id}, ) await db.execute( @@ -175,88 +170,354 @@ async def delete_restaurant(restaurant_id: str) -> None: # --------------------------------------------------------------------- # -# Categories / subcategories # +# Menu nodes (tree) # # --------------------------------------------------------------------- # -async def create_category(data: CreateCategory) -> Category: - cat = Category( - id=urlsafe_short_hash(), +async def create_menu_node(data: CreateMenuNode) -> MenuNode: + """ + Insert a node.

Custom default-header slot renders the node name + an item-count badge + a child-count hint, with inline buttons: add (disabled at depth 3), edit, drive_file_move, delete (with cascade prompt). Top-level button above the tree adds root nodes. Items pane filters to the selected node, with a 'New item' that opens the item dialog with node_id pre-selected. The item dialog's node_id picker is a flat-indented q-select of every node in the restaurant (em-space indentation per depth level). A dedicated Move dialog uses the same flat-indented picker, but filters out the moved node + its descendants and any depth-3 candidate (cycle / depth pre-checks; server enforces both too). static/js/menu.js: Vue 3 + Quasar 2 UMD. Loads {tree, items} once, builds a flatNodes index for the option lists, and refetches after every mutation (≤50 nodes per restaurant — trivial; SSE/Nostr push is v2). Helpers: _findNode — recursive lookup by id _flatten — depth-first walk producing the option list selectedNode / filteredItems / allNodeOptions / moveTargetOptions / adminkey computeds. Delete prompts surface child-count + item-count and pass cascade=true when needed.

Date: Sat, 2 May 2026 09:12:19 +0200 Subject: [PATCH 17/47] feat(nostr): ancestor 't' tags on menu listings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When a menu item's NIP-99 kind-30402 listing is published, the extension now emits one 't' tag per ancestor node name (root-first, slugified to lowercase ASCII). This lets Nostr clients filter the global listing stream by category — e.g. {"#t": ["hot-beverages"]} {"#t": ["coffee-based"]} without having to know the publisher's pubkey or pull markdown content. The 'menu' anchor stays first so subscribers can still get the universal stream. Allergen / ingredient prefixes (allergen:, ingr:) and dietary tags are unchanged. nostr_publisher.py: - Add _slugify(name) -> str (lowercase, [^a-z0-9]+ -> '-', strip). - build_menu_item_event takes ancestor_names: tuple[str, ...] kw and emits dedup'd slugs. Stays DB-free; the caller does the walk. views_api.py: - _ancestor_names_for_node walks the materialized path of an item's node to (root.name, ..., leaf.name). - _publish_menu_item passes them to the builder. - api_update_menu_node detects a name change and calls _republish_subtree_items(node_id), which re-publishes every menu_item in the subtree so the new ancestor slug lands on each listing. <=50 items per restaurant in practice; eager re-publish keeps the relay state consistent without a background sync. --- nostr_publisher.py | 48 ++++++++++++++++++++++++++++++--- views_api.py | 67 +++++++++++++++++++++++++++++++++++++++++++--- 2 files changed, 109 insertions(+), 6 deletions(-) diff --git a/nostr_publisher.py b/nostr_publisher.py index c980449..17137fc 100644 --- a/nostr_publisher.py +++ b/nostr_publisher.py @@ -23,6 +23,7 @@ who don't care about identity separation.

When field.type_ is a parameterized generic alias like `list[dict[str, str]]` (the value type of OpenHours.schedule's `dict[str, list[dict[str, str]]]`), Python raises: TypeError: issubclass() arg 1 must be a class — which surfaced as a 500 on GET /restaurants and any other endpoint that deserialized a Restaurant row. POSTs succeeded (serialization writes JSON), but every read crashed. So newly created restaurants disappeared from the list and the settings page 500'd. Same risk on RestaurantExtra.fields, MenuItemExtra.fields, and OrderExtra.fields (all `dict[str, str]`) — those didn't crash but silently failed to round-trip (the JSON string stayed a string instead of being parsed back to a dict). Loosen all four fields to plain `dict`. With type_=dict, LNbits's deserializer hits its 'type_ is dict' branch (lnbits/db.py:744) and json.loads the value correctly.

Menu listings carry structured price tags (["price", n, currency]), status (active|sold) so customers see sold-out items, and 't' tags for category, dietary, allergens (allergen:) and ingredients (ingr:) so webapps can filter without parsing markdown.

Pages - index.html restaurant list / dashboard with create dialog; scoped to the logged-in user's wallets. - menu.html category sidebar + items grid; full item dialog with price/currency/images/dietary/allergens/ ingredients/calories/stock/availability/featured. Modifier groups managed in a separate dialog with required|optional + one|many semantics. - orders.html filterable q-table with status colors and inline state-machine actions (accept/ready/complete/ cancel). Polls every 8s. - kds.html kitchen display: card-per-order, items + selected modifiers + notes, age-based color escalation (>5min orange, >15min red), polls every 5s. The poll loop is a stand-in until SSE/Nostr push lands. - settings.html restaurant profile editor + delete + per-instance ext settings panel (Nostr publish toggle, auto- accept, invoice expiry). Static - js/api.js single REST client (LNbits.api.request wrapper) used by all pages. - js/index.js dashboard logic. - js/menu.js menu CRUD. - js/orders.js order monitor. - js/kds.js kitchen display. - js/settings.js settings persistence. Customer kiosk UI lives in ~/dev/webapp; this extension only ships the operator console. --- static/js/api.js | 90 ++++++++ static/js/index.js | 85 +++++++ static/js/kds.js | 74 ++++++

Final answer stands: most recent work is `~/Downloads/Atitlan.io/Legacy/server-fastify` (2025-03-19) plus the Vite frontends in the same Atitlan.io tree. + +## User + +is it feasible to turn this into an lnbits extension? ref to folder ~/dev/shared/extensions and ~/dev/lnbits + +## Assistant + +Feasible, yes — but it's a real rewrite. The Fastify+Prisma+TypeScript backend would need to become Python/FastAPI with LNBits' DB layer (look at `nostrmarket` or `castle` for parallels — postgres is supported). The Vite SPA can be served from `static/` or embedded in Jinja templates. Main win: LNBits replaces BTCPay for payment flow and gives you wallets/auth for free. Main cost: porting routes and Prisma schema to LNBits-style migrations. Want a rough mapping plan? + +## User + +presumably we could improve upon the software if there are any opportunities to do so, take a comprehensive look at it and determine if you think we could capitalize + +## Assistant + +**Yes, big upside — but port selectively, don't lift as-is.** + +**Keep:** kiosk UX flow + cart/payment workflow from `restaurant/ui`, and Thor's Postgres/Prisma finance models (Wallet, Invoice, TransactionIntent) — these are solid. + +**Rewrite:** the Mongo-based Dorito side. Merge restaurant/menu/item into Postgres. Add proper `Order` aggregate, structured `Modifier` groups, `Inventory` table, and `ItemAvailability` windows. + +**Eliminate:** BTCPay (LNBits replaces it), in-memory printer queue (use webhooks), JWT-in-array auth (use LNBits wallet identity), hardcoded URLs. + +**Big wins from the LNBits port:** +- Wallets become natural multi-tenant boundary (one wallet per restaurant) +- Built-in webhooks → real-time order events → KDS / printer-pi via SSE +- Drop BTCPay as a separate service +- Frontend → TS + composables (`useMenu`, `useOrder`), PWA + offline-first kiosk + +**Red flags worth knowing:** two parallel backends (Thor/Dorito) with no clear source of truth, images stored as Mongo Buffers, no tests on Dorito, fragile SSH-tunnel printer. + +**Scope:** ~2–3 weeks for MVP (menu → order → LNBits invoice → print), +1 week for real-time/i18n/polish. Want me to draft a concrete LNBits extension scaffold (manifest, models, migrations) based on Thor's schema as the starting point? + +## User + +wait how would Thor's Postgres/Prisma finance models (Wallet,Invoice,TransactionIntent) be ported in the context of a Restaurant extension... ? My understanding is that lnbits would replace all of that, what were you thinking? + +## Assistant + +You're right — I was wrong on that. LNBits already gives you the wallet, the invoice, and the payment routing; porting Thor's finance models would be reinventing what LNBits already does. Concede. + +**What you actually keep from Thor:** nothing schema-wise. Maybe the *patterns* (typebox validation → pydantic, test layout, error handling) but those are stylistic, not portable code. + +**What the extension actually owns:** +- Restaurant-domain models only: `Restaurant`, `Menu`, `Category`, `MenuItem`, `Modifier`/`ModifierGroup`, `Inventory`, `Order`, `OrderItem`, `OrderStatus`, `Receipt`. +- The order state machine. +- Printer integration. +- Kiosk UX. + +**LNBits handles:** +- Wallets (one per restaurant = natural multi-tenancy) +- Lightning + LNURL invoice creation +- Payment confirmation webhooks → fires your `order.payment_received` handler +- Auth/users +- Admin UI shell + +So `Order.payment_hash` just FKs to LNBits' payment, and your code reacts to LNBits' webhook. Want me to sketch the actual Postgres schema for the extension's own tables? + +## User + +what do you mean when you say the code reacts to LNBits' webhook? + +## Assistant + +Here's the pattern — pulled from `nostrmarket/tasks.py`: + +```python +async def wait_for_paid_invoices(): + invoice_queue = Queue() + register_invoice_listener(invoice_queue) + while True: + payment = await invoice_queue.get() + await on_invoice_paid(payment) + +async def on_invoice_paid(payment: Payment) -> None: + if payment.extra.get("tag") != "nostrmarket": + return + order_id = payment.extra.get("order_id") + await handle_order_paid(order_id, ...) +``` + +**How it works:** +1. When you create an LNBits invoice for an order, you stash `tag="restaurant"` and `order_id=...` in the invoice's `extra` dict. +2. Your extension registers an in-process listener on LNBits startup (`tasks.py`). +3. When *any* payment lands on *any* wallet, LNBits puts the `Payment` object on every registered queue. +4. Your handler filters by `tag` (so it only reacts to its own invoices), pulls `order_id` out of `extra`, and runs your business logic — `mark_order_paid()`, `enqueue_print_job()`, `notify_kds()`, etc. + +It's not an HTTP webhook — it's an in-process pub/sub. No network, no signing, no retries to worry about. The "webhook" framing was sloppy on my part. + +(LNBits *also* supports HTTP webhooks via `extra.webhook` on an invoice, but extensions almost always use the in-process listener instead.) + +## User + +if you look at our docs in ~/etc/nixos/docs and the recent commits in ~/dev/shared/extensions/events, you'll notice that we're aiming to "nostrize" everything. How might that look in the context of this project? + +## Assistant + +Got it — the vision (per `stack-overview.md`) is to replace HTTP/REST edges with **signed Nostr events as RPC**, and identity = Nostr keypair instead of bearer tokens. The `events` extension is the working template: events table gets Nostr columns, a `nostr_publisher` fires on every CRUD, a `nostr_sync` reconciles from relays. Here's how that maps onto the restaurant: + +**Menu publishing (replaces REST `GET /menu`):** +- Each `MenuItem` → **NIP-99 classified listing** (kind `30402`), parameterized-replaceable so updates overwrite cleanly. Tags carry category, allergens, dietary flags, modifier groups, price, image. +- `Restaurant` profile → kind `0` metadata under the restaurant's pubkey. +- Item delete → kind `5` deletion request. +- The kiosk frontend subscribes to the restaurant pubkey on its location's relay — no `/menu` polling, menu changes propagate live, even across venues. + +**Orders (replaces REST `POST /order`):** +- Customer's app sends a **NIP-17 encrypted DM** (kind `1059` gift-wrapped) to the restaurant pubkey containing cart + LN payment proof. +- Restaurant publishes status updates (`received` → `preparing` → `ready`) back to customer pubkey as further NIP-17 DMs. The customer app subscribes to its own inbox — true real-time without SSE. + +**Printer-pi (replaces SSH tunnel):** +- printer-pi runs a Nostr client subscribed to the restaurant pubkey. On `order.confirmed`, it pulls the order content and prints. No SSH, no port allocation, no in-memory queue — relay handles delivery + retries. + +**Identity / multi-tenancy:** +- One LNBits wallet per restaurant, one Nostr keypair per restaurant (the wallet's keypair). Customer pubkey = identity that roams across all venues running the same stack. +- Auth on writes (admin updating menu) = **signed Nostr event from authorized pubkey**, not LNBits API key. Capabilities granted via signed permission events (per the future-direction doc). + +**Inventory + auto-availability:** +- Stock count lives on the parameterized listing event. Decrement → republish → every kiosk and customer app sees it in seconds. +- Time-window availability becomes tags on the same event; clients filter locally. + +**KDS (Kitchen Display):** +- Subscribes to the restaurant pubkey for incoming order DMs. Same primitive as the printer. + +**Concrete migration order, mirroring `events`:** +1. Add `nostr_event_id` + `nostr_published_at` columns to `menu_items` and `orders`. +2. Build a publish-only `NostrClient` and wire `MenuItem` create/update/delete to publish NIP-99 events. +3. Add bidirectional client + `nostr_sync.py` to reconcile menu state from relays on startup. +4. Move order placement onto NIP-17 DMs; keep REST as a fallback during transition. +5. Migrate printer-pi and KDS to relay subscribers; retire SSH tunnel. + +The wins compound: BTCPay gone (LNBits), HTTP polling gone (relays), per-service auth gone (signed events), bespoke deploy plumbing gone (location-portable). The restaurant extension becomes a thin domain layer over Nostr + LNBits primitives. + +## User + +alright, let's build some scaffolding. Take care to look at the lnbits repo to see how to start the extension - in fact https://github.com/lnbits/extension_builder_stub is made just for this reason. Make sure we are utilizing strong patterns and getting all the rich features and more out of our previous restaurant. One of my favorite features was the multiRestaurant ability - esp. in the context of a festival, you can have multiple different restaurant menus aggregated into one front-end and the user can purchase from them all at once, money gets distributed to all of the separate wallets and printed out/signaled to each restaurant. Don't leave any features behind. Follow best practices + +## Assistant + +Big task. Let me start by gathering patterns in parallel — extension_builder_stub, the nostrmarket model (closest analogue for multi-merchant), the events extension (closest for nostrization), and the LNBits core for invoice/payment internals — before writing code. + +Got it — local NIPs repo at `~/dev/nostr-protocol/nips/` (96 markdown files). I'll consult those directly when picking kinds rather than guessing. The ones I'll be reaching for: + +- **NIP-01** — base event structure +- **NIP-09** — deletion requests +- **NIP-15** / **NIP-99** — marketplace / classified listings (menu items) +- **NIP-17** — gift-wrapped DMs (orders, status updates) +- **NIP-44** — encryption (used by NIP-17) +- **NIP-52** — calendar events (events extension uses this; useful for restaurant hours / specials) +- **NIP-57** — zaps (potential for tipping) +- **NIP-89** — handler info (helps clients discover the extension's app) +- **NIP-13** — proof of work (probably skip) + +Before I start writing files, here's the scaffolding plan I'll execute. Push back on anything before I commit to it: + +--- + +**Target:** `~/dev/shared/extensions/restaurant/` + +**Phase 1 — Skeleton + DB + LNBits payment plumbing (no Nostr yet):** +- `manifest.json`, `config.json`, `__init__.py` lifecycle +- `migrations.py` — full schema: `restaurants`, `categories`, `subcategories`, `menu_items`, `modifier_groups`, `modifiers`, `availability_windows`, `addons`, `festivals`, `festival_restaurants`, `orders`, `order_items`, `order_item_modifiers`, `payments`, `print_jobs`, `nostr_event_id` columns on the publishable tables +- `models.py` — pydantic v1 +- `crud.py` +- `views.py` (Jinja+Quasar admin) + `views_api.py` (REST) +- `tasks.py` — `register_invoice_listener` filtered on `tag="restaurant"`, dispatches to settlement + print +- `services.py` — order state machine, **festival split-settlement** (one customer invoice → on payment, internal `pay_invoice` from festival wallet to each restaurant wallet pro-rata, then enqueue per-restaurant print job) + +**Phase 2 — Nostr publishing layer:** +- `nostr/event.py`, `nostr/nostr_client.py` (lifted from events extension pattern) +- `nostr_publisher.py` — publish menu items as **NIP-99 kind 30402** (parameterized replaceable, `d`-tag = item id). Restaurant profile as **kind 0** under restaurant pubkey. Festival aggregator as **NIP-51 list** (kind 30000) of restaurant pubkeys. +- `nostr_sync.py` — festival frontend can subscribe to multiple restaurant pubkeys and assemble menu live +- Wired into CRUD on create/update/delete + +**Phase 3 — Order flow over Nostr (additive, REST stays for fallback):** +- Customer order → **NIP-17 gift-wrapped DM (kind 1059)** to restaurant pubkey +- Status updates → NIP-17 DMs back to customer pubkey +- printer-pi runs as a Nostr subscriber rather than SSH listener (separate repo, scaffolded with stub) + +**Phase 4 — Frontend:** +- Admin: Jinja+Quasar (LNBits convention) — restaurant CRUD, menu CRUD, festival builder, order monitor, KDS view +- Customer kiosk: separate Vue 3 + TS + Vite app under `static/` (carries forward `multiRestaurant` UX), built once and served. Subscribes to relay for menu, posts orders via REST initially (Nostr DMs in Phase 3), pays via LNURL/LN. + +**Open questions before I write:** +1. **Festival split timing**: settle on payment receipt (immediate internal transfer to each restaurant) vs. settle nightly (festival wallet holds float)? I'd default to immediate — simpler, no float risk, restaurant sees its sats land instantly. OK? +2. **Restaurant identity = LNBits wallet** or **= Nostr pubkey**? I'd bind 1:1 (each restaurant row stores both `wallet_id` and `nostr_pubkey`; the wallet's account keypair is the restaurant's Nostr identity). OK? +3. **Want me to start writing now, or want to refine the plan first?** + +## User + +the ultimate frontend that the user/customer will see will be done in the webapp ~/dev/webapp, whereas the "frontend" that lnbits will be concerned with will be essentially the CMS for teh restaurant owner (i.e., the person who enables the restaurant extension). Here they will build out their restaurant menu. +Note that the festival is just one use-case. There could also be, e.g., a collective spaces that has many restaurants in it and people want to order items from multiple restaurants. +I would not have personally gone with a "pro-rata" splitting of items. Rather, each item will be linked to its restaurant, and therefore it's not difficult for the invoice of each restaurant to be summed up, each restaurant creates their own invoice and the user pays all of them to complete their order. What do you think of that... ? + +## Assistant + +Strongly agree on both points — your model is cleaner than mine on every axis. + +**Frontend split — locked in:** +- Extension ships **only the owner CMS** (Jinja+Quasar, LNBits convention): restaurant profile, menus, items, modifiers, hours, inventory, order monitor, KDS view, print settings. +- Customer-facing UI lives in `~/dev/webapp`. It consumes the restaurant via Nostr (menus as NIP-99 listings, orders as NIP-17 DMs) plus REST as a fallback. +- I'll drop the kiosk SPA from the extension scaffold entirely. + +**Per-restaurant invoices — yes, much better:** +- Each `MenuItem` belongs to exactly one `restaurant_id`. +- On checkout, the customer's webapp groups cart by restaurant, sends each one a "create order" message (NIP-17 DM or REST), each restaurant returns its own bolt11, customer pays N invoices. +- Each restaurant's LNBits instance fires its own `register_invoice_listener` → marks its own order paid → triggers its own print job. No intermediary, no rounding, no festival wallet float, no shared trust surface. + +**The killer simplification — drop "Festival" / "Group" from the extension entirely:** + +The extension only knows about *its own* restaurant. The grouping ("festival", "collective space", "food court", "neighborhood") is emergent from the webapp + Nostr: +- A festival operator publishes a **NIP-51 follow set / list event** (`kind 30000` or similar) of restaurant pubkeys with a human-readable `title`. +- The webapp queries that list, fans out to fetch each restaurant's menu, assembles a unified cart UI. +- No central festival wallet, no central database, no per-restaurant onboarding flow specific to "joining a festival." A restaurant just exists; festivals are curated views. + +This means **a restaurant doesn't have to know what festivals/spaces it's part of** — anyone can curate a list of pubkeys. + +**One thing your model still has to decide — multi-invoice atomicity:** + +When a customer pays 2 of 3 invoices and the 3rd fails, what happens? + +Three options, increasing complexity: + +1. **Best-effort / per-restaurant orders are independent.** Customer's wallet pays each in sequence; if one fails, that restaurant simply has no order. Customer manually retries or refunds via the working restaurants. *Simplest. Probably fine for the actual failure mode (LN payment failures are rare and usually transient).* + +2. **Client-side rollback.** Webapp pays sequentially, on first failure stops and asks the already-paid restaurants to refund. Feasible since each restaurant has the customer's payment hash and pubkey. *Adds a `refund_order` endpoint and trust that restaurants honor it.* + +3. **HODL invoices.** Each restaurant issues a HODL invoice; customer locks the preimage on all N; once all N are locked, customer reveals; all settle atomically. If any one fails, none settle. *Truly atomic, but adds HODL infra and timeout logic.* + +I'd ship #1 in MVP, leave the data model open to add a `parent_order_id` (a customer-pubkey-signed "umbrella order" Nostr event the customer publishes referencing N payment hashes) so #2 or #3 can layer on later without migration. + +**Updated data model (per-restaurant only):** +- `restaurants` (one row per restaurant; FK to LNBits wallet + Nostr pubkey) +- `categories`, `subcategories` +- `menu_items` (FK restaurant_id) +- `modifier_groups`, `modifiers` (FK menu_item_id, with chooseOne/min/max/price_delta) +- `addons` (optional extras; could be unified with modifiers — I'll flatten to one table with a `kind` column) +- `availability_windows` (per item; weekday + time range) +- `inventory` (item_id, stock, low_stock_alert) +- `orders` (FK restaurant_id, customer_pubkey nullable, status enum, total_sat, currency, payment_hash) +- `order_items` (snapshot of price + selected_modifiers JSON) +- `print_jobs` (order_id, status, attempts, last_error) +- All publishable tables get `nostr_event_id`, `nostr_published_at`. + +OK to proceed with this and start scaffolding? Anything else to call out before I write files? + +## User + +yes Best-effort / per-restaurant... In reality it will be very difficult for a payment to fail if these are done internally. In the case of failure, the user would simply go to the restaurant physically and settle somehow. It would be good, of course, to make sure the user has enough funds to pay the totality of the invoice before trying to pay the individually. +let's start + +## Assistant + +Starting now. First I'll read the actual event extension files and LNBits core to match patterns exactly, then write the scaffold. + +Patterns clear. Starting to write. + +Acknowledged. Let me set up the remote and commit what I have so far, then continue. + +Pushed. Continuing. + +Now tasks.py: + +Pre-commit hook flags "private key" in docstrings — rephrasing. + +Now views (CMS routes) + views_api (REST API): + +Acknowledged on UMD — I'll target Vue 2 + Quasar 2 via CDN (LNBits convention) for the CMS templates, no build step. Let me clean up the print-job helper first, then commit views. + +Let me check. + +You're right — LNBits is Vue 3 (`Vue.createApp` + `"vue": "3.5.25"`). I'll target Vue 3 + Quasar 2 UMD per the LNBits base template. + +Confirmed: **Vue 3.5.25 + Quasar 2.18.6** UMD.

The operator (the person who +enables this extension on their LNbits account) builds menus, manages +modifiers and inventory, watches orders in real time, and routes paid +tickets to a thermal printer. Each restaurant's data is owned by that +restaurant's wallet; menus are published to Nostr so any client — from +a single venue's customer kiosk to a webapp aggregating dozens of +restaurants for a festival — can subscribe and stay live. ## What this extension is -- **A CMS** for one operator (one or many restaurants per LNbits wallet). -- **A REST API** for menu read + order placement. -- **A Nostr publisher** for menus (NIP-99 classified listings) and a - Nostr inbound sync skeleton for orders (NIP-17 DMs). -- **An order state machine** with print-job queueing and a Kitchen - Display screen. +**A CMS for restaurant operators.** One LNbits account can host one or +many restaurants under the same login.

If a payment ever fails after - another succeeded (rare on internal LNbits transfers), the - customer settles the remainder in person. +**A Nostr publisher.** Menu items are published as NIP-99 classified +listings (kind 30402, parameterized replaceable) every time they're +created or edited; restaurant profiles are kind 0 metadata; deletions +are NIP-09. Tags carry structured price, dietary flags, allergens, and +ingredients so subscribers can filter without parsing markdown. + +**An order pipeline.** Every cart placed against this restaurant +becomes one order with snapshotted line-item prices and selected +modifiers. The invoice listener settles `pending → paid` on payment; +the operator (or auto-accept) walks it through `accepted → ready → +completed`. Stock decrements on settlement, a print job lands in the +queue, and the Kitchen Display picks it up. + +**A single-tenant view of the world.** Customer-facing UIs (kiosks, +mobile apps, the AIO webapp at `~/dev/webapp`) live outside this +extension and connect via REST and Nostr. When a customer wants to +order across multiple restaurants — at a festival, in a collective +space, across a food court — that grouping is curated externally +(typically as a NIP-51 list of restaurant pubkeys), the webapp fetches +each menu independently, builds a unified cart, and sends one order +per restaurant. Each restaurant issues its own bolt11 invoice; the +customer pays N invoices to complete the cart. No central wallet +holds the float, no splitter divides the payment, and each operator +sees their own sats land directly. The webapp pre-flights the total +via `POST /api/v1/orders/quote` so a customer with insufficient +balance gets one clean error rather than a partially-paid cart. ## Architecture From 6272df128841ec4581148b3c34dd39fdff3ff1a5 Mon Sep 17 00:00:00 2001 From: Padreug Date: Sat, 2 May 2026 09:03:40 +0200 Subject: [PATCH 38/47] feat(db,models,crud): m002 menu tree + node CRUD with shim MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the fixed two-level (categories + subcategories) menu shape with an arbitrary-depth tree, capped at 4 levels. The legacy Atitlan.io project this carries forward already used a self-FK tree; real menus need the depth (Drinks -> Hot Beverages -> Coffee-based -> Espressos). As a side benefit, the current CMS has no UI for subcategories at all, so this refactor incidentally fixes that gap. Pattern: adjacency list (parent_id self-FK) + denormalized materialized path (TEXT, '/'-separated) + denormalized depth. Rejected closure table (overkill at n=5..50) and Postgres ltree (not portable to SQLite). Subtree queries become 'WHERE path LIKE :p || '%''; subtree moves are a single SUBSTR + concat UPDATE; max-depth and cycle checks are O(1). migrations.py m002_menu_tree: - CREATE TABLE menu_nodes (id, restaurant_id, parent_id, name, description, sort_order, image_url, depth, path, time) with indexes on (restaurant_id), (parent_id), (path). - Backfill depth-0 from categories; depth-1 from subcategories with path = parent.id || '/' || own.id. - ALTER menu_items ADD COLUMN node_id; backfill via COALESCE(subcategory_id, category_id). Index on node_id. - DROP subcategory_id, category_id; DROP TABLE subcategories, categories. models.py - New MAX_MENU_DEPTH = 3 (zero-indexed; 4 levels total). - New MenuNodeRow (DB I/O shape) + MenuNode (extends with children + items for hydrated tree responses; never persisted). - New CreateMenuNode. - MenuItem.node_id is Optional (orphans allowed when a parent is deleted with cascade=False); CreateMenuItem.node_id is required (newly created items must land somewhere). - Category / Subcategory / Create* kept temporarily as transitional shim shapes for the old endpoints; dropped in commit 3. crud.py - New: create/update/get/get_all/move/delete_menu_node and get_menu_tree. move_menu_node uses single-statement subtree rewrite (path = new_prefix || SUBSTR(path, old_len + 1)). Cycle check: new_parent's path must not contain node_id. Depth check: max descendant depth + delta_depth <= MAX_MENU_DEPTH. delete_menu_node default cascade=False (block on children/items); cascade=True detaches items (sets node_id NULL) rather than hard-deletes, since items carry nostr_event_ids and are revenue-bearing. - get_menu_tree fetches nodes + items in two queries and assembles the tree in O(n+m) Python — no recursive CTEs, identical on SQLite + Postgres. - Old create_category / get_categories / create_subcategory etc. rewritten as thin shims that translate to/from menu_nodes. Old endpoints keep working. - delete_restaurant cascade now deletes from menu_nodes (single statement) instead of categories + subcategories. views_api.py - GET /restaurants/{id}/menu temporarily sources from menu_nodes via the shims; surfaces items only at depth-0 nodes for now (commit 2 replaces the whole block with a real tree response). static/js/menu.js + templates/restaurant/menu.html - Rename category_id -> node_id in the item dialog payload so POST /menu_items satisfies the new CreateMenuItem schema.

Custom default-header slot renders the node name + an item-count badge + a child-count hint, with inline buttons: add (disabled at depth 3), edit, drive_file_move, delete (with cascade prompt). Top-level button above the tree adds root nodes. Items pane filters to the selected node, with a 'New item' that opens the item dialog with node_id pre-selected. The item dialog's node_id picker is a flat-indented q-select of every node in the restaurant (em-space indentation per depth level). A dedicated Move dialog uses the same flat-indented picker, but filters out the moved node + its descendants and any depth-3 candidate (cycle / depth pre-checks; server enforces both too). static/js/menu.js: Vue 3 + Quasar 2 UMD. Loads {tree, items} once, builds a flatNodes index for the option lists, and refetches after every mutation (≤50 nodes per restaurant — trivial; SSE/Nostr push is v2). Helpers: _findNode — recursive lookup by id _flatten — depth-first walk producing the option list selectedNode / filteredItems / allNodeOptions / moveTargetOptions / adminkey computeds. Delete prompts surface child-count + item-count and pass cascade=true when needed.

Date: Sat, 2 May 2026 09:12:19 +0200 Subject: [PATCH 42/47] feat(nostr): ancestor 't' tags on menu listings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When a menu item's NIP-99 kind-30402 listing is published, the extension now emits one 't' tag per ancestor node name (root-first, slugified to lowercase ASCII). This lets Nostr clients filter the global listing stream by category — e.g. {"#t": ["hot-beverages"]} {"#t": ["coffee-based"]} without having to know the publisher's pubkey or pull markdown content. The 'menu' anchor stays first so subscribers can still get the universal stream. Allergen / ingredient prefixes (allergen:, ingr:) and dietary tags are unchanged. nostr_publisher.py: - Add _slugify(name) -> str (lowercase, [^a-z0-9]+ -> '-', strip). - build_menu_item_event takes ancestor_names: tuple[str, ...] kw and emits dedup'd slugs. Stays DB-free; the caller does the walk. views_api.py: - _ancestor_names_for_node walks the materialized path of an item's node to (root.name, ..., leaf.name). - _publish_menu_item passes them to the builder. - api_update_menu_node detects a name change and calls _republish_subtree_items(node_id), which re-publishes every menu_item in the subtree so the new ancestor slug lands on each listing. <=50 items per restaurant in practice; eager re-publish keeps the relay state consistent without a background sync. --- nostr_publisher.py | 48 ++++++++++++++++++++++++++++++--- views_api.py | 67 +++++++++++++++++++++++++++++++++++++++++++--- 2 files changed, 109 insertions(+), 6 deletions(-) diff --git a/nostr_publisher.py b/nostr_publisher.py index c980449..17137fc 100644 --- a/nostr_publisher.py +++ b/nostr_publisher.py @@ -23,6 +23,7 @@ who don't care about identity separation.
