Implement card-based interface for ConfigurableKitProduct attributes
This commit introduces a new user-friendly interface for managing product attributes:
1. **Form Changes** (products/forms.py):
- Removed 'option' field from ConfigurableKitOptionForm (values now inline)
- Updated ConfigurableKitProductAttributeFormSetCreate to only include name, position, visible
- Updated BaseConfigurableKitProductAttributeFormSet validation for new structure
2. **Template Updates** (products/templates/products/configurablekit_form.html):
- Replaced row-based attribute interface with card-based design
- Each card contains:
- Parameter name field
- Position field
- Visibility toggle
- Inline value inputs with add/remove buttons
- "Add parameter" button creates new cards
- "Add value" button adds inline value inputs
3. **JavaScript Enhancements**:
- addValueField(): Creates new value input with delete button
- initAddValueBtn(): Initializes add value button for each card
- addParameterBtn: Dynamically generates new parameter cards
- serializeAttributeValues(): Converts inline values to JSON for POST submission
- Form submission intercept to serialize data before sending
4. **View Updates** (products/views/configurablekit_views.py):
- Both Create and Update views now have _save_attributes_from_cards() method
- Reads attributes-X-values JSON from POST data
- Creates ConfigurableKitProductAttribute for each parameter+value combination
- Handles parameter deletion and visibility toggling
**Key Features**:
✓ One-time parameter name entry with multiple inline values
✓ Add/remove values without reloading page
✓ Add/remove entire parameters with one click
✓ No database changes required
✓ Better UX: card layout more intuitive than rows
✓ Proper JSON serialization for value transmission

# ConfigurableKitProduct Implementation - Completion Summary
|
||||
|
||||
## Status: ✅ COMPLETE
|
||||
|
||||
All tasks for implementing the M2M architecture for variable products have been successfully completed and tested.
|
||||
|
||||
---
|
||||
|
||||
## Work Completed
|
||||
|
||||
### 1. ✅ Database Model Architecture
|
||||
- **New Model**: `ConfigurableKitOptionAttribute`
|
||||
- M2M relationship between variants and attribute values
|
||||
- Unique constraint: one value per attribute per variant
|
||||
- Proper indexing on both fields
|
||||
- **Migration**: `0006_add_configurablekitoptionattribute.py`
|
||||
- Successfully created and applied
|
||||
- Database schema updated
|
||||
|
||||
### 2. ✅ Form Refactoring
|
||||
- **ConfigurableKitOptionForm**
|
||||
- Removed static 'attributes' field
|
||||
- Added dynamic field generation in `__init__`
|
||||
- Creates ModelChoiceField for each parent attribute
|
||||
- Pre-fills current values when editing
|
||||
- **BaseConfigurableKitOptionFormSet**
|
||||
- Enhanced validation to check all attributes are filled
|
||||
- Validates no duplicate kits
|
||||
- Validates only one default variant
|
||||
- Provides clear error messages per variant
|
||||
|
||||
### 3. ✅ View Implementation
|
||||
- **ConfigurableKitProductCreateView**
|
||||
- Updated `form_valid()` to save M2M relationships
|
||||
- Creates ConfigurableKitOptionAttribute records
|
||||
- Uses atomic transaction for consistency
|
||||
- **ConfigurableKitProductUpdateView**
|
||||
- Same implementation as Create view
|
||||
- Properly handles attribute updates
|
||||
|
||||
### 4. ✅ Template & UI
|
||||
- **Template Fixes**
|
||||
- Fixed syntax error: changed to proper `in` operator
|
||||
- Reordered sections: Attributes before Variants
|
||||
- Dynamic attribute select rendering
|
||||
- **JavaScript Enhancement**
|
||||
- Dynamic form generation when adding variants
|
||||
- Proper formset naming conventions
|
||||
- Copies attribute structure from first form
|
||||
|
||||
### 5. ✅ Testing & Validation
|
||||
- **Test Scripts Created**
|
||||
- `test_configurable_simple.py` - Model/form verification
|
||||
- `test_workflow.py` - Complete end-to-end workflow
|
||||
- **All Tests Passing**: ✅ Verified
|
||||
- Model relationships work correctly
|
||||
- M2M data persists and retrieves properly
|
||||
- Forms generate dynamic fields correctly
|
||||
- Views import and integrate properly
|
||||
|
||||
### 6. ✅ Documentation
|
||||
- `CONFIGURABLEKIT_IMPLEMENTATION_SUMMARY.md` - Technical details
|
||||
- `TESTING_GUIDE.md` - Complete manual testing guide
|
||||
- `COMPLETION_SUMMARY.md` - This file
