# ShopDB Flask Project

Modern rewrite of the classic-ASP shopdb. Built as a framework so sister GE Aerospace sites can adopt it. Plugin system is the product.

## Database

- **Active database:** `shopdb_flask` (MySQL, asset-based schema)
- **Legacy database:** `shopdb` (Classic ASP schema, used only for one-time data import via `scripts/import_from_mysql.py`)
- **Connection:** `.env` file. See `.env.example`.

Architecture decisions live in `docs/adr/`. Read those before making schema or contract changes.

- ADR-001: Asset model is the platform contract (Machine retires) - ACCEPTED
- ADR-002: Plugin contract versioning (semver) - ACCEPTED
- ADR-003: Plugin distribution model (in-tree bundled + filesystem-based external) - ACCEPTED
- ADR-004: Deployment topology (per-site instances, not multi-tenant) - ACCEPTED
- ADR-005: Equipment vs measuringtools plugin scope - ACCEPTED
- ADR-006: Plugin collector contract pattern - ACCEPTED
- ADR-007: Product versioning and releases - ACCEPTED
- ADR-008: Plugin migration ownership (per-plugin chains) - ACCEPTED
- ADR-009: Frontend plugin route gating - ACCEPTED
- ADR-010: Frontend plugin hook contract - ACCEPTED
- ADR-011: Machines rename + modeltypes retyping - ACCEPTED

## Coding convention

`CONTRIBUTING.md` defines naming rules (DB tables, columns, Python, JS, Vue, API). Pre-commit hook at `scripts/check-naming-and-style.sh` enforces them. Read `CONTRIBUTING.md` before naming any new identifier.

## Current state (as of 2026-07-12)

Refactor phases 0-5 landed; phase 6 (multi-site distribution readiness) largely complete; the last big milestone is the legacy-data import + a production pilot.

### Phases done

- **Phase 0**: 6 ADRs accepted, naming convention v1, pre-commit style hook
- **Phase 1**: 8 smoke tests + 7 production-config tests, Flask-SQLAlchemy 3 fixtures, uv lockfile, hardened ProductionConfig
- **Phase 2**: contract surface defined (`__contract_version__`, `BasePlugin` hooks, `docs/PLUGIN-HOOKS.md`), 51 contract tests
- **Phase 3**: manifest-first loader, fail-loud/isolate policy, contract-version range checking, auto-register core blueprints, `shopdb.api` namespace, `BasePlugin.get_setting/set_setting` helpers
- **Phase 4**: `flask plugin new <name>` CLI, scaffold templates, 14 canary tests, `docs/PLUGIN-QUICKSTART.md`
- **Phase 5**: ADRs moved to `docs/adr/`, Alembic baseline migration, per-site deploy artifacts (`Dockerfile`, `docker-compose.yml`, `docs/DEPLOY.md`)

### Active state

- 781 tests passing, naming/style check green, Gitea Actions CI (backend + naming + frontend build)
- `__contract_version__` at 0.10.0 (product `__version__` 0.6.0, tags v0.5.0/v0.6.0 - distinct series, ADR-007; a large [Unreleased] pile is due a release cut)
- 11 bundled plugins all satisfy contract: computers, employees, knowledgebase, machines, measuringtools, network, notifications, printers, slides, usb, warranty
- Core Alembic chain: baseline `68b3947ae14f` -> head `7d22_apitokens_scopes` (29 core migrations). Each plugin owns its own chain (ADR-008); deploy runs `flask db upgrade` then `flask plugin upgrade-all`. Reproducible + idempotent from empty.
- API is migration-complete: an admin PAT + docs/IMPORT-API.md let a script/LLM import the whole legacy DB (X-Import-Mode preserves timestamps).
- Pre-1.0 framework; sister sites should pin tight `core_version` ranges until contract reaches 1.0

### Deferred

- Equipment data migration (one-shot script for legacy ASP shopdb -> assets). Per ADR-001, only `category='Equipment' AND machinenumber IS NOT NULL` migrates. Skill `migrating-asset-schema` documents the pattern; the actual one-shot script lives in `scripts/migration/` when run.
- Printers retirement: legacy `PrinterData` model + frontend changes. Coordinated with the equipment data migration.
- (DONE 2026-07-11) `measuringtools` plugin (ADR-005) is built and bundled; docs/PLUGIN-GUIDE.md narrates its construction as the plugin tutorial.
- (DONE) Frontend plugin hook contract (ADR-010): get_settings_cards / get_asset_panels / get_map_overlays / get_asset_presentation shipped; generic renderers for panels/overlays land incrementally.
- (DONE) Per-plugin Alembic chains (ADR-008): every bundled plugin carries its own chain; no plugin uses db.create_all().
- Legacy ASP data import against the renamed schema (unblocked; run via docs/IMPORT-API.md) + a production pilot deployment.

## Quick start

```bash
# Start dev environment
~/start-dev-env.sh

# Activate venv and install deps
cd /home/camp/projects/shopdb-flask
source venv/bin/activate
pip install -r requirements.txt

# Configure environment
cp .env.example .env
# Edit .env with DB credentials, JWT secrets

# Create / update database tables via the Alembic chain
flask db upgrade

# Seed RBAC, default settings, and reference data (all idempotent)
flask seed permissions
flask seed settings
flask seed reference-data

# Restart services
pm2 restart shopdb-flask-api shopdb-flask-ui
```

## Service URLs

- Flask API: http://localhost:5001
- Flask UI: http://localhost:5173
- Legacy ASP (data source for one-time import): http://192.168.122.151:8080

## Plugin structure

```
plugins/
  <plugin_name>/
    __init__.py
    plugin.py          # BasePlugin implementation
    manifest.json      # Plugin metadata (name, version, dependencies, api_prefix)
    models/
      __init__.py      # Export all models
      <model>.py       # SQLAlchemy models
    api/
      __init__.py
      routes.py        # Flask Blueprint
    services/          # Optional, business logic
    schemas/           # Optional, marshmallow schemas
    migrations/        # Optional, plugin-specific Alembic migrations
```

Each plugin must have:

- `models/__init__.py` exports all models
- `plugin.py` extends `BasePlugin`
- `manifest.json` with metadata (single source of truth per ADR-002)
- No direct imports from core code (use the contract surface defined in ADR-001)

## Key files

- `shopdb/__init__.py` - app factory, blueprint registration
- `shopdb/plugins/base.py` - BasePlugin ABC, PluginMeta dataclass
- `shopdb/plugins/loader.py` - filesystem discovery, dependency-aware loading
- `shopdb/core/api/assets.py` - example of optional plugin imports
- `frontend/src/router/index.js` - frontend routing
- `frontend/src/components/AppSidebar.vue` - navigation menu
- `docs/adr/` - architecture decision records

## Migration notes

- `migrations/DATA_MIGRATION_GUIDE.md` - one-time import from legacy ASP shopdb
- `migrations/MIGRATE_USB_DEVICES_FROM_EQUIPMENT.md` - USB device migration from equipment table
- `migrations/FIX_LOCATIONONLY_EQUIPMENT_TYPES.md` - LocationOnly equipment type fix
- `migrations/PRODUCTION_MIGRATION_GUIDE.md` - production import methods
- `migrations/rename_underscore_columns.sql` - one-time rename of snake_case columns to lowercase concatenated (per CONTRIBUTING.md)
- `migrations/versions/` - the core Alembic chain (baseline `68b3947ae14f` -> head `7d16_directoryemployees`). Run `flask db upgrade` to apply.
