Two open endpoints: an item lookup by scanned code and the take POST - the product's first unauthenticated write, held to the decision record's bar (decrement-only, badge-attributed server-side, bounded, physically rate-limited; justification in the plugin README). The /parts-kiosk route is a full-screen no-auth view beside /shopfloor: a hidden always-focused input consumes keyboard-wedge scans for whichever step is active, TouchKeypad (net-new 3x4 grid) takes the quantity, and a success screen resets after a few seconds. Manual type-in fallbacks cover damaged labels. Kiosk test proves open access, the over-take guard, the badge policy, and cache==ledger afterward.

# Printedparts plugin
|
|
|
|
3D-printed parts inventory + kiosk checkout
|
|
|
|
This plugin was generated by `flask plugin new printedparts`. It satisfies the framework contract out of the box. Replace the example model and routes with your domain.
|
|
|
|
## What's here
|
|
|
|
- `plugin.py` - the `PrintedpartsPlugin` class extending `BasePlugin`. Edit `init_app` for custom setup, `on_install` to seed reference data.
|
|
- `models/printedparts.py` - example Asset extension table. Replace `examplefield` with your domain fields.
|
|
- `api/routes.py` - example list and detail endpoints. Add CRUD as needed.
|
|
- `schemas/__init__.py` - marshmallow schema stub for request/response validation.
|
|
- `tests/test_plugin.py` - smoke tests asserting contract compliance.
|
|
- `manifest.json` - plugin metadata. Bump `version` on changes; keep `core_version` range broad.
|
|
|
|
## Common edits
|
|
|
|
| You want to... | Do this |
|
|
|---|---|
|
|
| Add a hook (search, navigation, dashboard widget) | Override the method in `PrintedpartsPlugin`. See `docs/PLUGIN-HOOKS.md`. |
|
|
| Accept external collector data | Override `get_collector_schema()` to return a JSON Schema. See ADR-006. |
|
|
| Add another model | Create `models/<other>.py`, export it in `models/__init__.py`, return it in `get_models()`. |
|
|
| Add a CLI command | Override `get_cli_commands()` returning a list of Click commands. |
|
|
|
|
## Frontend
|
|
|
|
Vue components for this plugin live under `frontend/src/views/printedparts/` (per project convention). Backend scaffolding does not generate frontend yet; copy from an existing plugin's view files (e.g., `frontend/src/views/network/`) as a starting point.
|
|
|
|
## Install and run
|
|
|
|
```bash
|
|
flask plugin install printedparts
|
|
flask db migrate -m "Add printedparts plugin tables"
|
|
flask db upgrade
|
|
pytest plugins/printedparts/tests/
|
|
```

## Why the kiosk take endpoint is unauthenticated
|
|
|
|
`POST /api/printedparts/kiosk/take` is the product's first open WRITE (every
|
|
other kiosk endpoint is a read). Accepted deliberately, against the criteria
|
|
in docs/proposals/printedparts-plugin.md:
|
|
|
|
1. Decrement-only: it can reduce stock of an active item, nothing else.
|
|
2. Fully attributed: it refuses to act without a badge that resolves under
|
|
the site policy; every action lands in the ledger with SSO + name + time.
|
|
3. Bounded blast radius: worst case is stock counts driven low - visible in
|
|
the ledger and reversible with an adjust.
|
|
4. Physically rate-limited: it serves a touch screen on the shop floor;
|
|
nothing enumerable, nothing worth scraping.
|
|
|
|
Any future open-write endpoint must clear the same bar.
