From 07f77603eb4c9d9f2c796cc4bd6f803840250dfc Mon Sep 17 00:00:00 2001 From: Quality App Developer Date: Fri, 30 Jan 2026 12:30:56 +0200 Subject: [PATCH] Implement approved/rejected quantity triggers and warehouse inventory Database Triggers Implementation: - Added automatic quantity calculation triggers for scanfg_orders - Added automatic quantity calculation triggers for scan1_orders (T1 phase) - Triggers calculate based on CP_base_code grouping (8 digits) - Quality code: 0 = approved, != 0 = rejected - Quantities set at insertion time (BEFORE INSERT trigger) - Added create_triggers() function to initialize_db.py Warehouse Inventory Enhancement: - Analyzed old app database quantity calculation logic - Created comprehensive trigger implementation guide - Added trigger verification and testing procedures - Documented data migration strategy Documentation Added: - APPROVED_REJECTED_QUANTITIES_ANALYSIS.md - Old app logic analysis - DATABASE_TRIGGERS_IMPLEMENTATION.md - v2 implementation guide - WAREHOUSE_INVENTORY_IMPLEMENTATION.md - Inventory view feature Files Modified: - initialize_db.py: Added create_triggers() function and call in main() - Documentation: 3 comprehensive guides for database and inventory management Quality Metrics: - Triggers maintain legacy compatibility - Automatic calculation ensures data consistency - Performance optimized at database level -

set when record is inserted +- They are **NOT** updated if other records are inserted later +- Each record's quantities represent the state AT THE TIME OF INSERTION + +### 3. **Example Impact** +If you insert records in different order, quantities will differ: + +**Order 1:** Insert Approved, then Rejected +``` +Approved record: approved_qty=1, rejected_qty=0 +Rejected record: approved_qty=1, rejected_qty=1 ← Includes the approved! +``` + +**Order 2:** Insert Rejected, then Approved +``` +Rejected record: approved_qty=0, rejected_qty=1 +Approved record: approved_qty=1, rejected_qty=1 ←

rejected. + +--- + +## 🚀 Migration Approach + +### Option 1: Use Database Triggers (Recommended) + +**Pros:** +- Exact replica of old system behavior +- Automatic calculation +- Consistent with legacy data +- Performance optimized at DB level + +**Cons:** +- Complex trigger logic +- Hard to debug +- Must match old behavior exactly + +### Option 2: Calculate in Python + +**Pros:** +- Easy to understand and debug +- Flexible logic +- Can add validation + +**Cons:** +- Performance impact for high volume +- Must call calculation function on every insert +- Must ensure consistency + +### Option 3: Store Pre-calculated Values (Batch) + +**Pros:** +- Can cache results +- Fast queries +- Good for reporting + +**Cons:** +- Data can become stale +- Requires batch update process +- Extra complexity + +--- + +## 📋 Implementation Steps for v2 + +### Step 1: Create Generated Column +```sql +ALTER TABLE scanfg_orders ADD COLUMN +cp_base_code VARCHAR(10) GENERATED ALWAYS AS (SUBSTRING(CP_full_code, 1, 10)) STORED; +``` + +### Step 2: Create Trigger +Copy the `set_quantities_fg` trigger from old app, adjusted for new table structure + +### Step 3: Test +Insert test records and verify quantities calculate correctly + +### Step 4: Update Routes +Update FG Scan route to use quality_code properly: +- User selects "Approved" or "Rejected" +- System sets quality_code = 0 (approved) or quality_code = 1 (rejected) +- Trigger automatically sets quantities + +--- + +## 🔍 Current v2 Status + +### What We Have Now +- scanfg_orders table with box_id and location_id +- Manual quantity input (NOT automatic!) + +### What We Need to Add +1. quality_code field interpretation (0 vs 1+) +2. Database triggers for automatic calculation +3. Update FG Scan form to capture quality status properly +4.
