Quick Box Checkpoint - Implementation Complete

What Was Implemented

1. Backend Routes Added to /srv/quality_app-v2/app/modules/quality/routes.py

✅ POST /quality/api/create-quick-box

• Creates new box with auto-incremented number (BOX00000001, etc.)
• Stores in boxes_crates table
• Returns JSON with box_number and box_id

✅ POST /quality/api/generate-box-label-pdf

• Generates PDF label with:
  • 8cm × 5cm landscape format
  • "BOX Nr: BOX00000001" text
  • Code128 barcode
• Returns base64-encoded PDF for printing

✅ POST /quality/api/assign-cp-to-box

• Assigns CP code to box
• Stores in box_contents table
• Links boxes_crates to CP code with quantity

2. Frontend JavaScript Updated in /srv/quality_app-v2/app/templates/modules/quality/fg_scan.html

✅ Form Submission

• When "Scan To Boxes" checkbox is enabled
• After all form fields are entered and defect code triggers auto-submit
• Posts scan to database
• Shows modal for box assignment

✅ Quick Box Label Creation

• Creates box with auto-increment
• Generates PDF label with barcode
• Sends to printer via QZ Tray
• Shows popup box number for user entry
• Fallback if QZ Tray unavailable

✅ Box Assignment Modal

• Shows after scan is recorded
• Box number auto-populated from quick creation
• User enters quantity
• Assigns CP to box on submit
• Closes and resets form for next scan

Workflow Implemented

1. User fills FG Scan form
   - Operator Code (OP)
   - CP Code (CP)
   - OC1 Code (OC)
   - OC2 Code (OC)
   - Defect Code (000-999)

2. When defect code complete (3 digits)
   - Auto-submits form

3. If "Scan To Boxes" checkbox ENABLED:
   ✅ Scan saved to database
   ✅ Success notification shown
   ✅ Modal appears
   
4. User clicks "Quick Box Label Creation"
   ✅ New box created (BOX00000001)
   ✅ PDF generated with barcode
   ✅ Label sent to printer
   ✅ Box number populated in modal

5. User confirms quantity
   - Clicks "Assign"
   ✅ CP assigned to box
   ✅ Saved to database
   ✅ Modal closes
   ✅ Form resets
   ✅ Ready for next scan

6. If "Scan To Boxes" checkbox NOT enabled:
   ✅ Regular form submission
   ✅ No modal
   ✅ Standard POST behavior

Files Modified

1. /srv/quality_app-v2/app/modules/quality/routes.py

   • Added 3 new API routes (~150 lines)
   • Added required imports (base64, BytesIO, reportlab, etc.)

2. /srv/quality_app-v2/app/templates/modules/quality/fg_scan.html

   • Updated form submission handler
   • Implemented "Scan To Boxes" logic
   • Replaced stubbed "Quick Box Label Creation"
   • Implemented box assignment modal handler
   • Added error handling and notifications

Testing Instructions

Test 1: Regular FG Scan (Checkbox Unchecked)

1. Open FG Scan page
2. Leave "Scan To Boxes" UNCHECKED
3. Fill form: OP0001, CP00002042-0001, OC1234, OC5678, 000
4. Expected: Form submits normally, page reloads, scan appears in table

Test 2: FG Scan with Box Assignment

1. Open FG Scan page
2. Check "Scan To Boxes" checkbox
3. Fill form: OP0001, CP00002042-0001, OC1234, OC5678, 000
4. Expected:
   • Scan saves to database
   • Modal appears
   • "Quick Box Label Creation" button visible

Test 3: Quick Box Creation & Printing

1. After Test 2 modal appears
2. Click "Quick Box Label Creation"
3. Expected:
   • Success notification "Box BOX00000001 created"
   • Box number auto-fills in modal
   • If QZ Tray running: Label prints to printer
   • If QZ Tray not running: Warning message shown

Test 4: Box to CP Assignment

1. After box created (Test 3)
2. Enter quantity (e.g., "1")
3. Click "Assign"
4. Expected:
   • Success notification "CP assigned to box"
   • Modal closes
   • Form resets
   • Ready for next scan

Test 5: Database Verification

After tests complete, verify in database:

-- Check created boxes
SELECT id, box_number, status, created_by, created_at 
FROM boxes_crates 
ORDER BY created_at DESC 
LIMIT 5;

-- Check CP assignments
SELECT b.box_number, bc.cp_code, bc.quantity, bc.created_at
FROM box_contents bc
JOIN boxes_crates b ON bc.box_id = b.id
ORDER BY bc.created_at DESC 
LIMIT 5;

-- Check scans recorded
SELECT operator_code, cp_code, defect_code, date, time 
FROM scanfg_orders 
ORDER BY id DESC 
LIMIT 5;

Deployment Notes

1. Dependencies Added (auto-installed):

   • reportlab (PDF generation)
   • code128 barcode library

2. Database Tables (auto-created on first use):

   • boxes_crates - Box inventory
   • box_contents - CP to box mapping

3. QZ Tray (optional but recommended):

   • Install QZ Tray application on workstations
   • Network printers connected and configured
   • If not available, app falls back to notifications

Error Scenarios Handled

✅ Box creation fails → Error message, no modal ✅ PDF generation fails → Error message, modal shows anyway ✅ QZ Tray not connected → Warning, modal shows with fallback ✅ Printer not found → Warning, but box still created ✅ CP assignment fails → Error message, modal stays open for retry ✅ Missing form fields → Validation errors as before

Next Steps

1. Restart docker to apply changes
2. Run the 5 tests above
3. Verify database entries
4. Test with/without QZ Tray
5. Test multiple scans in sequence

Code Quality

✅ Error handling on all operations ✅ User notifications for all outcomes ✅ Async/await for clean code flow ✅ Fallback options when services unavailable ✅ Database transactions and constraints ✅ Proper logging for debugging ✅ Commented code sections ✅ No breaking changes to existing features
