Form Submission Flow

NEW APP

User scans product with defect code 000
         ↓
Form validation succeeds
         ↓
AJAX POST to /quality/fg_scan
         ↓
Scan saved to database
         ↓
Modal displays with:
  - CP code filled in
  - Box number input focused
  - Ready for user input
         ↓
User selects action:
  Option A: Click "📦 Quick Box Label Creation"
    → Creates new box
    → Prints label
    → Assigns CP to new box
    
  Option B: Enter box number + quantity
    → Click "Assign to Box"
    → Validates inputs
    → POST to /quality/api/assign-cp-to-box
    → Links CP to existing box
    → Reloads page
    
  Option C: Click "Skip"
    → Modal closes
    → Page reloads
    → Scan remains unassigned

OLD APP

Same workflow, but:
- No quantity field (always 1 unit)
- No separate footer container
- Quantity not configurable
- Otherwise identical behavior

JavaScript Event Handlers

NEW APP - Assign Button Handler

File: fg_scan.html

document.getElementById('assignToBox').addEventListener('click', async function() {
    const boxNumber = document.getElementById('boxNumber').value.trim();
    const boxQty = document.getElementById('boxQty').value.trim();

    if (!boxNumber) {
        showNotification('⚠️ Please enter a box number', 'warning');
        return;
    }

    if (!boxQty || isNaN(boxQty) || parseInt(boxQty) < 1) {
        showNotification('⚠️ Please enter a valid quantity', 'warning');
        return;
    }

    try {
        this.disabled = true;
        this.textContent = '⏳ Assigning...';

        // Submit box assignment
        const response = await fetch('{{ url_for("quality.assign_cp_to_box") }}', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json',
                'X-Requested-With': 'XMLHttpRequest'
            },
            body: JSON.stringify({
                box_number: boxNumber,
                cp_code: currentCpCode,
                quantity: boxQty
            })
        });

        if (!response.ok) {
            throw new Error(`Server error: ${response.statusText}`);
        }

        const data = await response.json();

        if (data.success) {
            showNotification(
                `✅ CP ${currentCpCode} assigned to box ${boxNumber}!`,
                'success'
            );
            
            // Close modal
            document.getElementById('boxAssignmentModal').style.display = 'none';
            
            // Clear box inputs
            document.getElementById('boxNumber').value = '';
            document.getElementById('boxQty').value = '';
            
            // Reload page to show updated scans table after a brief delay
            setTimeout(() => {
                location.reload();
            }, 1000);
            
        } else {
            throw new Error(data.error || 'Unknown error');
        }
    } catch (error) {
        console.error('Error:', error);
        showNotification(`❌ Error: ${error.message}`, 'error');
    } finally {
        this.disabled = false;
        this.textContent = 'Assign';
    }
});

OLD APP - Assign Button Handler

File: py_app/app/templates/fg_scan.html

document.getElementById('assign-to-box-btn').addEventListener('click', async function() {
    // Check if scan-to-boxes is enabled
    if (!scanToBoxesEnabled) {
        showNotification('⚠️ "Scan to Boxes" feature is disabled', 'warning');
        closeBoxModal();
        return;
    }
    
    const boxNumber = document.getElementById('scan-box-input').value.trim();
    if (!boxNumber) {
        showNotification('⚠️ Please scan or enter a box number', 'warning');
        return;
    }
    
    try {
        await assignCpToBox(boxNumber);
        showNotification(`✅ CP ${currentCpCode} assigned to box ${boxNumber}`, 'success');
        setTimeout(() => closeBoxModal(), 1000);
    } catch (error) {
        showNotification('❌ Error: ' + error.message, 'error');
    }
});

Key Differences & Observations

✅ Improvements in New App

1. Quantity Field: New app adds quantity input (not just 1 unit)
2. Flexbox Layout: Modal uses flex for better responsive design
3. Better Spacing: More padding and margins for readability
4. Font Sizes: Box input is 1.1em (easier for barcode scanners)
5. Event Listeners: Consistent event listener pattern (not inline onclick)
6. Modal Footer: Separate footer container for better organization
7. Error Validation: Separate quantity validation check
8. Button Labeling: Clear "Assign to Box" label (not just "Assign")

⚠️ Breaking Changes Between Apps

1. Modal ID: Changed from box-assignment-modal to boxAssignmentModal

   • Any external code referencing old ID will break

2. Input IDs: Changed from scan-box-input to boxNumber

   • Old app's direct references to element IDs will fail

3. Button IDs: Changed from quick-box-create-btn to quickBoxLabel

   • Event listeners must be updated

4. Display Method: Changed from display: 'block' to display: 'flex'

   • May affect CSS styling

5. Button Handler: Changed from onclick="closeBoxModal()" to event listener

   • More scalable but different approach

📊 Form Input Summary

New App Form Fields

• Inputs: 3 fields
  1. Box Number (text, required)
  2. Quantity (number, required, min=1, default=1)
  3. Hidden inputs: currentCpCode (JavaScript variable)

Old App Form Fields

• Inputs: 1 field
  1. Box Number (text, required)
  2. Hidden inputs: currentCpCode (JavaScript variable)

Backend API Endpoint Comparison

NEW APP

• Route: /quality/api/assign-cp-to-box (POST)
• Handler: quality_bp.route in app/modules/quality/routes.py
• Parameters:

  {
    "box_number": "BOX-001",
    "cp_code": "CP-XXXXXXXXXX",
    "quantity": 1
  }
  

OLD APP

• Route: /warehouse/assign_cp_to_box (POST)
• Handler: warehouse_bp.route in py_app/app/routes.py
• Parameters: Similar structure but route path differs

---

Validation Rules

NEW APP Validation

// Box Number Validation
if (!boxNumber) {
    showNotification('⚠️ Please enter a box number', 'warning');
    return;
}

// Quantity Validation
if (!boxQty || isNaN(boxQty) || parseInt(boxQty) < 1) {
    showNotification('⚠️ Please enter a valid quantity', 'warning');
    return;
}

OLD APP Validation

const boxNumber = document.getElementById('scan-box-input').value.trim();
if (!boxNumber) {
    showNotification('⚠️ Please scan or enter a box number', 'warning');
    return;
}
// No quantity validation (always 1)

---
