- flask plugin new now scaffolds the frontend too: List/Detail/Form views on the global styles, a gated route module (ADR-009), and an api-client snippet emitted into the plugin dir. Views are written before the route file so a partially generated plugin cannot 500 the dev server. - docs/PLUGIN-EXTERNAL-REPO.md + scripts/test-external-plugin.sh: how a sister site develops a plugin in its own repo and runs the framework contract tests in CI against a pinned framework ref (script verified to fail on a broken core_version pin). - docs/CONTRACT-STABILITY.md: settled vs churning contract surface and the provisional 1.0 criteria. - CLAUDE.md active-state refresh (contract 0.6.0, 11 plugins, 340 tests, measuringtools done). Known limitation documented: Path.rglob does not descend symlinks, so the import-surface contract test skips symlinked external plugins. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# Plugins
|
|
|
|
shopdb-flask is a framework. The plugins listed here are the pieces other GE Aerospace facilities can install, build, or skip per ADR-003. Bundled plugins ship in the framework repo. External plugins live in their own repos and drop into `<repo>/plugins/<name>/` at install time.
|
|
|
|
## Bundled (ship with the framework)
|
|
|
|
These plugins are in `plugins/` in this repo. Enable per site with `flask plugin install <name>`.
|
|
|
|
| Plugin | Tracks | Notes |
|
|
|--------|--------|-------|
|
|
| `equipment` | Manufacturing machinery: 5-axis mills, lathes, broachers, heat treatment ovens | Manually entered. See [ADR-005](adr/ADR-005-equipment-vs-measuringtools.md). Subtype tables for FOCAS / CLM / MTConnect controller protocols (planned). |
|
|
| `computers` | Shop-floor PCs and engineering workstations | Fed by the PXE pipeline collector per [ADR-006](adr/ADR-006-collector-contract.md). |
|
|
| `printers` | Network and shop-floor printers | Optional Zabbix integration for supply tracking. Legacy `PrinterData` retiring per ADR-001. |
|
|
| `network` | Switches, routers, access points, IDFs as locations | Asset-only; cleanest of the bundled set. |
|
|
| `usb` | USB devices issued to shop-floor users | Lightweight checkout / check-in. |
|
|
| `notifications` | Shop-floor notifications, recognitions, kiosk feed | Used by `ShopfloorDashboard.vue`. |
|
|
| `measuringtools` | Metrology and inspection instruments: calipers, micrometers, thread/bore/height gages, indicators | Per [ADR-005](adr/ADR-005-equipment-vs-measuringtools.md). Calibration lifecycle with derived status. First plugin built on the matured scaffold; its walkthrough is [PLUGIN-GUIDE.md](PLUGIN-GUIDE.md). Ships `default_enabled: false`. |
|
|
|
|
## Building your own
|
|
|
|
Guides:
|
|
|
|
- [PLUGIN-QUICKSTART.md](PLUGIN-QUICKSTART.md) - generate, customize, install, and test a plugin in 30 minutes using `flask plugin new`.
|
|
- [PLUGIN-GUIDE.md](PLUGIN-GUIDE.md) - the full narrative walkthrough of building the `measuringtools` plugin, the exemplar that exercises every current framework feature (models, per-plugin migrations, authz, hooks, frontend integration, tests).
|
|
- [PLUGIN-EXTERNAL-REPO.md](PLUGIN-EXTERNAL-REPO.md) - developing a plugin in its own repo per ADR-003: repo layout, symlink dev workflow, `core_version` pinning, and a runnable CI harness (`scripts/test-external-plugin.sh`) that tests the plugin against a pinned framework ref.
|
|
- [CONTRACT-STABILITY.md](CONTRACT-STABILITY.md) - path to contract 1.0: what is settled vs still churning, the bump rules, and how much a sister site can safely build on today.
|
|
|
|
The contract is locked in [ADR-001](adr/ADR-001-asset-as-platform-contract.md) and versioned per [ADR-002](adr/ADR-002-plugin-versioning.md).
|
|
|
|
Quick path:
|
|
|
|
```bash
|
|
flask plugin new cameras --description "Tracks shop-floor surveillance cameras"
|
|
# edit plugins/cameras/models/cameras.py with your fields
|
|
flask plugin install cameras
|
|
```
|
|
|
|
## Migrations (per-plugin chains)
|
|
|
|
Each plugin that owns tables carries its own Alembic chain under
|
|
`plugins/<name>/migrations/`, with a per-plugin version table
|
|
`alembic_version_<name>` independent of the core `alembic_version`. Ownership is
|
|
split at a fixed cutover (see [ADR-008](adr/ADR-008-plugin-migration-ownership.md)):
|
|
|
|
- The core chain (`flask db upgrade`) created every table that existed through
|
|
its head, including the bundled-plugin tables. Each bundled plugin's `0001`
|
|
migration is a stamp-only no-op anchor recording that fact.
|
|
- From the cutover forward, a change to a plugin's schema lands as
|
|
`plugins/<name>/migrations/versions/000N_*.py`, never in the core chain. The
|
|
core chain is reserved for core tables.
|
|
- A plugin built AFTER the cutover (e.g. `measuringtools`) is different: the
|
|
core chain never created its tables, so its `0001` is a REAL baseline that
|
|
creates them, not a no-op anchor. See [PLUGIN-GUIDE.md](PLUGIN-GUIDE.md) for
|
|
the anchor-vs-baseline distinction.
|
|
|
|
Deploys and upgrades run `flask db upgrade` then `flask plugin upgrade-all`.
|
|
`upgrade-all` stamps every plugin anchor and applies any later plugin
|
|
migrations; it is idempotent. The registry (`instance/plugins.json`) records
|
|
which revisions each plugin has applied in `migrations_applied`.
|
|
|
|
## Distribution conventions
|
|
|
|
For sister-site plugins (per [ADR-003](adr/ADR-003-plugin-distribution.md)):
|
|
|
|
- Plugin lives in its own git repo: `gitea.proudtech.net/<your-site>/<pluginname>`
|
|
- Adopting site clones or symlinks into their `<repo>/plugins/<name>/`
|
|
- Plugin manifest declares `core_version` range matching the framework version they target
|
|
- Plugin readme explains: what it tracks, who maintains it, where to file issues
|
|
|
|
## Naming policy
|
|
|
|
Plugin names follow the framework's naming convention (lowercase concatenated, no underscores or dashes; full words preferred over acronyms). See [CONTRIBUTING.md](../CONTRIBUTING.md). Plugin name collisions across sites are not enforced; the convention recommends prefixing site-specific plugins with the site code (e.g., `wjsf-shippingstation`) when there is risk of overlap.
