🎯 Key Tables Now in Both Files

Core Tables

• users, user_credentials, roles
• user_modules, user_permissions
• quality_inspections, application_settings

Warehouse Tables

• warehouse_locations
• boxes_crates ← BOX TRACKING
• box_contents ← BOX TRACKING

Quality & Scanning

• scanfg_orders WITH location_id & box_id ← INTEGRATED BOX TRACKING
• cp_location_history ← AUDIT TRAIL

System Tables

• qz_pairing_keys (printer integration)
• api_keys (API management)
• backup_schedules (backup automation)
• worker_manager_bindings (hierarchy)

Total: 18+ tables in both files

---

🔄 Execution Steps (Both Files Now Identical)

Step 0: Check & Repair Database
    └─ Detect if database exists
    └─ If exists: Run verification & repair
    └─ If new: Skip and start fresh

Step 1: Create Database
    └─ CREATE DATABASE IF NOT EXISTS

Step 2: Create Tables (18+)
    └─ All tables with FK & indexes
    └─ Box tracking fully integrated

Step 3: Insert Default Data
    └─ 6 roles
    └─ Admin user
    └─ Warehouse locations
    └─ App settings

Step 4: Verify Database
    └─ Confirm all tables exist
    └─ Count records
    └─ Report status

Result: ✅ Database Ready

💾 scanfg_orders Integration

New Columns in scanfg_orders

box_id BIGINT           -- Links to boxes_crates
location_id BIGINT      -- Links to warehouse_locations

Foreign Keys

FOREIGN KEY (box_id) REFERENCES boxes_crates(id) ON DELETE SET NULL
FOREIGN KEY (location_id) REFERENCES warehouse_locations(id) ON DELETE SET NULL

Indexes

INDEX idx_box_id (box_id)
INDEX idx_location_id (location_id)

Result

✅ Each FG scan can now be:

• Assigned to a specific box
• Tracked at a warehouse location
• Linked to box contents
• Audited for movements

---

🛡️ Redundancy & Robustness Benefits

✅ Redundancy

• Both init_db.py and initialize_db.py are identical
• Either can be used independently
• No single point of failure for database setup
• Backup initialization option available

✅ Robustness

• Automatic database structure verification
• Missing tables/columns auto-repair
• Foreign key constraints enforced
• Comprehensive error handling
• Professional logging for debugging
• Database validation after setup

✅ Upgrade Safety

• Detects existing databases
• Preserves existing data
• Adds missing elements safely
• Schema evolution supported
• Safe to run multiple times

---

📋 Usage Instructions

Initialize Fresh Database

# Option A: Using init_db.py
python3 init_db.py

# Option B: Using initialize_db.py (now identical)
python3 initialize_db.py

# Option C: Use both (safe for redundancy)
python3 init_db.py && python3 initialize_db.py

Verify Installation

# Check database
docker exec quality_app_mariadb mariadb -u root quality_db -e "SHOW TABLES;"

# Expected output: 18+ tables
# Including: boxes_crates, box_contents, scanfg_orders, etc.

Test Auto-Repair

# Simulate missing column
docker exec quality_app_mariadb mariadb -u root quality_db << 'SQL'
ALTER TABLE scanfg_orders DROP COLUMN location_id;
SQL

# Run init_db.py again
python3 init_db.py

# Should detect and repair
# Log: "✓ Added location_id column to scanfg_orders"

✨ Highlights

🎯 Complete Box Tracking Integration

FG Scan Entry
    ↓
scanfg_orders (operator_code, CP_full_code, quality_code)
    ├─ box_id (NEW) → boxes_crates
    ├─ location_id (NEW) → warehouse_locations
    └─ created_at (tracked)
    
Result: Each scan tracked to box and location

🔄 Upgrade Path

Old Database → Run init_db.py
    ↓
SchemaVerifier detects missing columns
    ↓
Auto-adds location_id, box_id, indexes, FK
    ↓
New Database → With box tracking enabled

🛠️ Professional Code

✅ Proper logging (formatted with timestamps)
✅ Error handling (graceful failures)
✅ Configuration management (Config + Env vars)
✅ Database verification (validation step)
✅ Documentation (inline + external)

---

🔒 Data Safety

When You Run init_db.py:

1. ✅ Existing data is preserved
2. ✅ Missing tables are created
3. ✅ Missing columns are added
4. ✅ Foreign keys are maintained
5. ✅ Indexes are created
6. ✅ All changes are committed

Rollback Safety:

• Foreign keys prevent orphaned data
• ON DELETE SET NULL/CASCADE configured
• Constraints maintain referential integrity
• Transactions ensure consistency
