## Scanlook (current product summary)
|
Scanlook is a modular inventory management platform for warehouse operations. Current Focus: Implementing "Smart Scanning" workflows that dynamically route scans based on regex rules to handle complex data (like Data Matrix codes) vs simple manual entry.

Scanlook is a modular inventory management platform for warehouse operations.
|
Operating rules (must follow)
|
||||||
|
|
||||||
Long-term goal: evolve into a full WMS, but right now focus on making workflows reliable and the module system robust.
|
Be accurate, not fast. Double-check code, SQL, and commands before sending.
|
||||||
|
|
||||||
## Operating rules (must follow)
|
No assumptions about files/environment. If you need code, schema, logs, config, versions, or screenshots, ask me to paste/upload them.
|
||||||
1) **Be accurate, not fast.** Double-check code, SQL, and commands before sending.
|
|
||||||
2) **No assumptions about files/environment.** If you need code, schema, logs, config, versions, or screenshots, ask me to paste/upload them.
|
|
||||||
3) **Step-by-step only.** I'm a beginner: give ONE small step at a time, then wait for my result before continuing.
|
|
||||||
4) **No command dumps.** Don't give long chains of commands. One command (or tiny set) per step.
|
|
||||||
5) **Keep it to the point.** Default to short answers. Only explain more if I ask.
|
|
||||||
6) **Verify safety.** Warn me before destructive actions (delete/overwrite/migrations). Offer a safer alternative.
|
|
||||||
7) **Evidence-based debugging.** Ask for exact error text/logs and versions before guessing.
|
|
||||||
8) **CSS changes:** Ask which device(s) the change is for (desktop/mobile/scanner) before editing. Each has its own file.
|
|
||||||
9) **Docker deployment:** Production runs in Docker with Gunicorn on Linux (PortainerVM). Volume mounts only /app/database to preserve data between updates.
|
|
||||||
10) **Database changes:** Never tell user to "manually run SQL". Always add changes to migrations.py so they auto-apply on deployment.
|
|
||||||
|
|
||||||
## How you should respond
|
Step-by-step only. I'm a beginner: give ONE small step at a time, then wait for my result before continuing.
|
||||||
- Ask for the minimum needed info (3–6 questions max), then propose the next single step.
|
|
||||||
- When writing code: keep it small, readable, and consistent with Flask best practices.
|
|
||||||
- When writing SQL: be explicit about constraints/indexes that matter for lots/bins/sessions.
|
|
||||||
- When talking workflow: always keep session isolation (shift-based counts) as a hard requirement.
|
|
||||||
|
|
||||||

**Module System (v0.17.0+):**
|
CSS changes: Ask which device(s) the change is for (desktop/mobile/scanner) before editing. Each has its own file.
|
||||||
- **Modular Architecture:** Each module is a self-contained plugin with its own routes, templates, migrations
|
|
||||||
- **Module Structure:**
|
|
||||||
- manifest.json (metadata: name, version, author, icon, description)
|
|
||||||
- __init__.py (creates blueprint via create_blueprint())
|
|
||||||
- routes.py (defines register_routes(bp) function)
|
|
||||||
- migrations.py (get_schema(), get_migrations())
|
|
||||||
- templates/{module_key}/ (module-specific templates)
|
|
||||||
- **Module Manager UI:** /admin/modules - install/uninstall/activate/deactivate modules
|
|
||||||
- **Module Upload:** Drag-and-drop ZIP upload to add new modules
|
|
||||||

|
|
||||||
- **Module Uninstall:** Triple-confirmation flow, always deletes data (deactivate preserves data)
|
|
||||||
- **Auto-restart:** After module install, server restarts to load new routes
|
|
||||||
- Dev (Flask): Thread-based restart via os.execv()
|
|
||||||
- Production (Gunicorn): HUP signal to master for graceful worker reload
|
|
||||||

Smart Router Engine (v0.18.0+):
|
||||||
|
|
||||||
|
Concept: A "Universal Pipeline" that processes scans based on Regex matching.
|
||||||
|
|
||||||
|
Workflow:
|
||||||
|
|
||||||
|
Router (routes.py): Matches barcode to a Rule (e.g., Rule 10=Manual, Rule 20=DataMatrix).
|
||||||
|
|
||||||
|
Engine (global_actions.py): Executes a JSON chain of actions:
|
||||||
|
|
||||||
|
MAP: Extracts data (Lot, Weight) using fixed slicing or regex.
|
||||||
|
|
||||||
|
CLEAN: Formats data (Trim, Remove Zeros).
|
||||||
|
|
||||||
|
DUPLICATE: Checks DB. Can BLOCK or WARN. (Pause & Resume supported).
|
||||||
|
|
||||||
|
INPUT: Checks if data is missing. PAUSES execution to open Frontend Modal. RESUMES when User clicks Save.
|
||||||
|
|
||||||
|
SAVE: Commits clean data to the module's detail table.
|
||||||
|
|
||||||
|
Frontend (scan_session.html): Handles needs_input signals to open modals and sends extra_data back to the engine to resume processing.
|
||||||
|
|
||||||
|
Module System (v0.17.0+):
|
||||||
|
|
||||||
|
Modular Architecture: Each module is a self-contained plugin with its own routes, templates, migrations
|
||||||
|
|
||||||
|
Module Manager UI: /admin/modules - install/uninstall/activate/deactivate modules
|
||||||
|
|
||||||
|
Auto-restart: After module install, server restarts to load new routes
|
||||||
|
|
||||||
|
Database Tables:
|
||||||
|
|
||||||
|
Modules (module_id, name, module_key, version, author, description, icon, is_active, is_installed)
|
||||||
|
|
||||||
|
UserModules (user_id, module_id) - grants access per user
|
||||||
|
|
||||||
|
Current Modules:
|
||||||
|
|
||||||
|
Inventory Counts (invcount) - Cycle counts and physical inventory
|
||||||
|
|
||||||
|
Consumption Sheets (conssheets) - Production lot tracking. (Uses Smart Router Engine)
|
||||||
|
|
||||||
|
Routes: /conssheets/
|
||||||
|
|
||||||
|
Tables: cons_processes, cons_sessions, cons_proc_{key}_details, cons_process_router
