A review ofd60ed60and8b9b936found five things. Three were introduced by those commits. REFUSING A NAMED DEVICE MADE A MARKER PC CLAIM ITS OPERATION. _sync_partmarker returned [] both for "not a marker PC" and for "a marker PC that linked nothing", and the caller reads [] as the first - so a bay whose asset-id.txt named something unresolvable fell through to the ordinary machine link, and for a marker PC the machine number IS the operation. It took an active link to a record that can only have one holder while several markers share it, and the warning said "not linked". The previous behaviour minted a twin; this traded that for a contested operation. None now means "not a marker PC" and is the only answer that lets the machine link run; the response normalises it away so the API shape is unchanged. A DORMANT CHALLENGER WAS PROMOTED BY DELETING A FILE. Recording a challenger dormant leaves a row that the next cycle finds as `reuse` and reactivated with no incumbent check - so a second PC took a live device by its enrollment file becoming unreadable. Both reuse branches re-check incumbency now, which is what _sync_machine_link always did. AN INCUMBENT UNDER ANOTHER COLLECTOR LABEL WAS INVISIBLE. Incumbency was queried on our own label, but on a CMM the instrument IS the reported bay, so the incumbent's link is the machine sync's row. A second PC naming that instrument found no incumbent and linked actively: two live holders of one instrument, each invisible to the other. Incumbency now counts any collector-owned label. A row made BY HAND carries none of them and is still excluded - a person's link is not the collector's to archive. THE NETWORK FORM LOCKED OUT THE ROWS IT NEEDED TO FIX. Asset number is disabled while editing, correctly, but the payload is built in script so the blank was still sent - and the new server-side guard rejects it. A device with no asset number could not be saved at all, and the field could not be typed into. It now unlocks only for a record that loaded without one, with a hint saying why. "2 in 4.0d" WAS THE LABEL LYING. Replacements are counted across the whole history window; basisdays is only how long the current cartridge has been in. Joining them with "in" claimed two changes inside four days - the exact shape reported as unbelievable, except here the data was right. Now "2, this one 4.0d". Two toner dips the same review found: A MULTI-POLL OUTAGE STILL MINTED A PHANTOM SWAP. Only single readings were dropped, so 90, 0, 0, 90 survived and 0 -> 90 scored as a change. Dips of any length are handled now. One bad sample stays a candidate whatever the polling cadence, because a reading is an instant; several consecutive low ones only count as one outage when they are close together, since days at zero is a real empty period. That time bound also separates an outage from a swap, ordinary consumption, and a second swap, which have the same shape in levels alone. THE DIP FILTER ATE REAL SWAPS OF NEARLY-FULL CARTRIDGES. Recovery was tested with an absolute difference, so 95 then 5 then 100 read as a recovery because 100 and 95 are close, and the swap evidence was deleted. Toner only falls: a recovery comes back at or BELOW where it left, a new cartridge comes back higher. The review also proved by reverting each feature that the previous tests did not pin the median burn rate or the near-full rule - both passed with the bug restored. Verified by the same method that all four toner behaviours now fail when reverted, and the burst assertion is tight enough to tell 0.2 from 0.88.
ShopDB Flask
A modern rewrite of the classic ASP/VBScript ShopDB application using Flask (Python) and Vue 3. This application manages shop floor machines, PCs, printers, applications, and related infrastructure for manufacturing environments.
Overview
ShopDB tracks and manages:
- Machines - CNC equipment, CMMs, inspection systems, etc.
- PCs - Shopfloor computers, engineering workstations
- Printers - Network printers with Zabbix supply integration
- Network devices - Switches, routers, and the subnet browser
- Measuring tools - Gage-lab instruments with calibration tracking
- Applications - Software deployed across the shop floor, with per-PC install tracking
- Employees - Directory, recognition and training notifications
- Warranties - Coverage records with Dell warranty lookups
- USB devices - CMMC check-in/out tracking
- Knowledge Base - Documentation and troubleshooting guides
- GE-Enforce manifests - Imaging/software manifest editing and fleet compliance
Tech Stack
Backend:
- Python 3.14 with Flask
- SQLAlchemy ORM
- MySQL 5.7+ database (5.6 works with extra utf8mb4 config; see docs/DEPLOY.md)
- JWT authentication
- Plugin architecture for extensibility
Frontend:
- Vue 3 with Composition API
- Vue Router for navigation
- Pinia for state management
- Vite build system

Naming Conventions
To maintain consistency with the legacy ShopDB database and codebase, the following naming standards apply:
Database
- Table names: Lowercase, single word, no underscores or dashes
- Examples:
assets,computers,printers,businessunits
- Examples:
- Column names: Lowercase, single word, no underscores or dashes
- Examples:
assetid,assetnumber,hostname,isactive,createddate
- Examples:
- Foreign keys: Referenced table name +
id- Examples:
locationid,vendorid,modelnumberid,computertypeid
- Examples:
- Boolean columns: Prefixed with
isorhas- Examples:
isactive,isshopfloor,iscolor,isdhcp,islicenced
- Examples:
Code
- Python variables: Follow database naming where applicable (lowercase, no underscores for model fields)
- JavaScript variables: camelCase for local variables, but match API field names from backend
- Vue components: PascalCase for component names
- CSS classes: Lowercase with dashes for multi-word classes
API
- Endpoints: Lowercase, plural nouns
- Examples:
/api/machines,/api/computers,/api/locations
- Examples:
- Query parameters: Lowercase, single word
- Examples:
?locationid=5,?isactive=true,?assettype=computer
- Examples:
Style Guidelines
- No emojis in code, comments, documentation, or UI
- Keep UI functional and professional
- Dark theme is the default
- Consistent table layouts across all list views
Setup
Prerequisites
- Python 3.14
- Node.js 18+
- MySQL 5.7+ (5.6 works with extra utf8mb4 config; see docs/DEPLOY.md)
ShopDB Flask uses MySQL as the canonical database. SQLite is used only for the
test suite (TestingConfig in shopdb/config.py points at an in-memory
SQLite). Do not run dev or production against SQLite.
Distribution
Source lives here. The Windows installer ships as a release asset rather than a
file in the repository - it is around 240 MB, well past what a repository takes
and well inside what a release asset does. There is no package or image
registry; a site installs from that .exe or builds from source.
Fast path (Docker)
The Docker image builds the Vue frontend and serves it from the API container, so a container deploy needs no separate Node build step.
cp .env.example .env
# Edit .env: set SECRET_KEY, JWT_SECRET_KEY, DATABASE_URL, CORS_ORIGINS,
# and the MYSQL_* passwords (see docs/CONFIG.md for every variable).
docker compose up -d --build
# Create the schema and seed the platform data (idempotent, safe to re-run):
docker compose exec api flask db upgrade
docker compose exec api flask seed permissions
docker compose exec api flask seed settings
docker compose exec api flask seed reference-data
Then browse to the site and complete the first-run setup wizard at /setup
(it creates the first admin account and captures site identity). To create the
admin headlessly instead of using the wizard:
docker compose exec api flask seed admin --username admin --email admin@facility.example.com
Manual path (venv + Node)
# Backend
python -m venv venv
source venv/bin/activate
pip install -r requirements.txt
cp .env.example .env
# Edit .env with your database credentials and secrets.
export FLASK_APP=shopdb
flask db upgrade
flask plugin upgrade-all # per-plugin schema (ADR-008)
flask seed permissions
flask seed settings
flask seed reference-data
flask run --port 5001 # MUST be 5001 - the frontend dev server proxies here
# Frontend (separate terminal)
cd frontend
npm install
npm run dev # dev server on :5173
npm run build # production build into frontend/dist (served by Flask)
Complete first-run setup at /setup, or run flask seed admin for a headless
admin account. The repo ships VS Code config in .vscode/ (F5 debugs the
backend; a "Dev site" task runs both servers). A fuller day-one walkthrough,
including VS Code and troubleshooting, is the DEVELOPMENT-SETUP page in the
project wiki.
To import a site's legacy data, use the HTTP import surface: an admin API
token plus docs/IMPORT-API.md drive the whole migration
through documented endpoints (X-Import-Mode preserves original timestamps).
scripts/site_imports/wjf/ is the reference site's loader, kept as a worked
example of the whole sequence.
Which deployment route
| Target | Use |
|---|---|
| Windows Server + IIS (how sister sites run) | docs/INSTALL-WINDOWS.md - one installer .exe, offline, no manual IIS work. Day 2: docs/OPERATE-WINDOWS.md |
| Linux / Docker, air-gapped | docs/DEPLOY-AIRGAP.md |
| Linux / Docker, connected | docs/DEPLOY.md |
For every environment variable and Setting key see docs/CONFIG.md.
What the Windows installer requires
The installer checks all of this before it changes anything and refuses rather than half-installing.
| Minimum | Notes | |
|---|---|---|
| Windows Server | 2019 (build 10.0.17763) | Ships IIS 10.0, which is therefore the earliest IIS supported. Server 2016 is also IIS 10.0 but falls below the build floor and is refused. |
| Windows client (test boxes) | 10 22H2 (build 10.0.19045) or 11 | Pro or higher - Home has no IIS at all. |
| Architecture | 64-bit | The payload is cp314 win_amd64. |
| IIS Web Server role | installed beforehand | Install-WindowsFeature -Name Web-Server -IncludeManagementTools. Needs no internet. |
| Free disk | 5 GB | Refused below this. 40 GB is comfortable once uploads and config backups accumulate. |
| Database | bundled MySQL 8.4 LTS, or your own | Bring credentials if you use an existing server. |
The binding constraint is the operating system rather than IIS: the payload is Python 3.14 plus HttpPlatformHandler and URL Rewrite, and the handler itself runs on older IIS. An older host is untested rather than known-broken.
If you must deploy onto something older, docs/INSTALL-WINDOWS-IIS.md is the manual procedure and has no OS gate - it even documents MySQL 5.6, which is that era of machine. The trade is stated there: it produces a server the installer will not subsequently upgrade.
Configuration
Environment variables (.env):
| Variable | Description |
|---|---|
DATABASE_URL |
MySQL connection string |
SECRET_KEY |
Flask secret key |
JWT_SECRET_KEY |
JWT signing key |
JWT_ACCESS_TOKEN_EXPIRES |
Access token TTL (seconds) |
LOG_LEVEL |
Logging verbosity |
API Documentation
The REST API follows standard conventions:
| Method | Endpoint | Description |
|---|---|---|
| GET | /api/machines |
List machines (filterable by type) |
| GET | /api/machines/:id |
Get machine details |
| POST | /api/machines |
Create machine |
| PUT | /api/machines/:id |
Update machine |
| DELETE | /api/machines/:id |
Soft delete machine |
Each asset plugin exposes the same CRUD pattern on its own prefix
(/api/computers, /api/printers, /api/network, /api/measuringtools),
and cross-cutting asset endpoints live under /api/assets.
Query parameters for list endpoints:
page- Page number (default: 1)perpage- Items per pagesort- Sort fielddir- Sort direction (asc/desc)search- Search termassettype- Filter by asset type (computer, printer, machine, networkdevice, measuringtool)
Where to start
docs/START-HERE.md routes by what you are here to do - standing up a site, deploying the shop-floor tools, writing a plugin, integrating with the API, or diagnosing something. On the published mirror the same page is the wiki's front door.
Plugin System
ShopDB supports plugins for extending functionality. See CONTRIBUTING.md for plugin development guidelines.
The image bundles these plugins; only the ones a site installs are loaded. The current count and each plugin's version and migration head are in docs/PROJECT-MAP.md, which is generated:
- backups - Machine configuration backups (NTLARS/DNC, CMM, part marker, UDC) with revision history and diffs
- computers - Shopfloor PCs and workstations, collector fleet ingest
- employees - Employee directory
- geenforce - GE-Enforce imaging/software manifests and fleet compliance
- machines - CNC, CMM, and other shop-floor machines
- measuringtools - Gage-lab instruments with calibration tracking
- knowledgebase - Documentation and troubleshooting guides
- network - Network devices and subnets
- notifications - Shopfloor notifications and recognition feed
- printedparts - 3D-printed part catalogue, kiosk issue tracking and stock alerts
- printers - Extended printer management with Zabbix integration
- slides - TV/kiosk slideshows
- tools - Tech Tools: barcode and QR generation laid out for real label stock
- usb - CMMC USB check-in/out tracking
- warranty - Warranty records with Dell lookups

This project replicates functionality from the classic ASP/VBScript ShopDB site. Key mappings:
| Legacy | Modern |
|---|---|
| ASP/VBScript | Flask/Python |
| Classic ADO | SQLAlchemy |
| Server-side HTML | Vue 3 SPA |
