The system allows creating variable products with attributes and dynamically selecting ProductKits for each variant. + +## Changes Made + +### 1. Database Models ([products/models/kits.py](myproject/products/models/kits.py)) + +#### ConfigurableKitOptionAttribute Model (NEW) +- **Purpose**: M2M relationship between ConfigurableKitOption variants and ConfigurableKitProductAttribute values +- **Fields**: + - `option`: ForeignKey to ConfigurableKitOption (with related_name='attributes_set') + - `attribute`: ForeignKey to ConfigurableKitProductAttribute +- **Constraints**: + - unique_together: ('option', 'attribute') - ensures one value per attribute per variant + - Indexed on both fields for query performance + +#### ConfigurableKitOption Model (UPDATED) +- **Removed**: TextField for attributes (replaced with M2M) +- **Relationship**: New reverse relation `attributes_set` through ConfigurableKitOptionAttribute + +### 2. Database Migrations ([products/migrations/0006_add_configurablekitoptionattribute.py](myproject/products/migrations/0006_add_configurablekitoptionattribute.py)) + +- Created migration for ConfigurableKitOptionAttribute model +- Applied successfully to database schema + +### 3. Forms ([products/forms.py](myproject/products/forms.py)) + +#### ConfigurableKitOptionForm (REFACTORED) +- **Removed**: 'attributes' field from Meta.fields +- **Added**: Dynamic field generation in __init__ method + - Generates ModelChoiceField for each parent attribute + - Field names follow pattern: `attribute_{attribute_name}` + - For edit mode: pre-populates current attribute values +- **Example**: If parent has "Длина" and "Упаковка" attributes: + - Creates `attribute_Длина` field + - Creates `attribute_Упаковка` field + +#### BaseConfigurableKitOptionFormSet (ENHANCED) +- **Added**: Comprehensive validation in clean() method + - Checks for duplicate kits + - Validates all attributes are filled for each variant + - Ensures max one default variant + - Provides detailed error messages per variant number + +#### Formsets (UPDATED) +- ConfigurableKitOptionFormSetCreate: extra=1, fields=['kit', 'is_default'] +- ConfigurableKitOptionFormSetUpdate: extra=0, fields=['kit', 'is_default'] + +### 4. Views ([products/views/configurablekit_views.py](myproject/products/views/configurablekit_views.py)) + +#### ConfigurableKitProductCreateView.form_valid() (UPDATED) +- Iterates through option_formset +- Saves ConfigurableKitOption with parent +- Creates ConfigurableKitOptionAttribute records for each selected attribute +- Uses transaction.atomic() for data consistency + +#### ConfigurableKitProductUpdateView.form_valid() (UPDATED) +- Same logic as Create view +- Properly deletes old attribute relationships before creating new ones + +### 5. Template ([products/templates/products/configurablekit_form.html](myproject/products/templates/products/configurablekit_form.html)) + +#### Form Structure (REORDERED) +- Attributes section now appears BEFORE variants +- Users define attributes first, then bind ProductKits to attribute combinations + +#### Dynamic Attribute Display +- Variant form rows iterate through dynamically generated attribute fields +- Renders select dropdowns for each attribute field +- Field names follow pattern: `options-{formIdx}-attribute_{name}` + +#### JavaScript Enhancement +- addOptionBtn listener dynamically generates attribute selects +- Clones structure from first form's attribute fields +- Properly names new fields with correct formset indices + +### 6. Test Scripts (NEW) + +#### test_configurable_simple.py +- Verifies models and relationships exist +- Checks form generation +- Validates view imports + +#### test_workflow.py +- Complete end-to-end workflow test +- Creates ConfigurableKitProduct +- Creates attributes with multiple values +- Creates variants with M2M attribute bindings +- Verifies data retrieval + +**Test Results**: All tests PASSED ✓ +- Successfully created 3 variants with 2 attributes each +- All data retrieved correctly through M2M relationships +- Form validation logic intact + +## Usage Workflow + +### Step 1: Create Variable Product +1. Go to /products/configurable-kits/create/ +2. Enter product name and SKU +3. Define attributes in the attributes section: + - Attribute Name: e.g., "Длина" + - Attribute Values: e.g., "50", "60", "70" + +### Step 2: Create Variants +1. In variants section, for each variant: + - Select a ProductKit + - Select values for each attribute + - Mark as default (max 1) +2. Form validates: + - All attributes must be filled + - No duplicate kits + - Only one default variant + +### Step 3: Save +- System creates: + - ConfigurableKitOption records + - ConfigurableKitOptionAttribute relationships + - All in atomic transaction + +## Data Structure + +``` +ConfigurableKitProduct (parent product) +├── parent_attributes (ConfigurableKitProductAttribute) +│ ├── name: "Длина", option: "50" +│ ├── name: "Длина", option: "60" +│ ├── name: "Упаковка", option: "БЕЗ" +│ └── name: "Упаковка", option: "В УПАКОВКЕ" +│ +└── options (ConfigurableKitOption - variants) + ├── Option 1: kit=Kit-1 + │ └── attributes_set (ConfigurableKitOptionAttribute) + │ ├── attribute: Длина=50 + │ └── attribute: Упаковка=БЕЗ + │ + ├── Option 2: kit=Kit-2 + │ └── attributes_set + │ ├── attribute: Длина=60 + │ └── attribute: Упаковка=В УПАКОВКЕ + │ + └── Option 3: kit=Kit-3 + └── attributes_set + ├── attribute: Длина=70 + └── attribute: Упаковка=БЕЗ +``` + +## Key Features + +✓ **M2M Architecture**: Clean separation between attribute definitions and variant bindings +✓ **Validation**: Ensures all attributes present for each variant +✓ **Dynamic Forms**: Attribute fields generated based on parent configuration +✓ **Data Consistency**: Atomic transactions for multi-part operations +✓ **User-Friendly**: Attributes section appears before variants in form +✓ **Flexible**: Attributes can be reordered and positioned + +## Notes + +- All attributes are REQUIRED for each variant if defined on parent +- Maximum ONE value per attribute per variant (enforced by unique_together) +- Maximum ONE default variant per product (enforced by validation) +- No backward compatibility with old TextField attributes (intentional - fresh start) +- Supports any number of attributes and values + +## Testing + +Run the test scripts to verify implementation: + +```bash +cd myproject +python test_configurable_simple.py # Basic model/form tests +python test_workflow.py # Full workflow test +``` + +Both tests should pass with "OK: ALL TESTS PASSED!" message. diff --git a/myproject/products/forms.py b/myproject/products/forms.py index 7c59b92..b2e65fa 100644 --- a/myproject/products/forms.py +++ b/myproject/products/forms.py @@ -625,6 +625,7 @@ class ConfigurableKitProductForm(forms.ModelForm): class ConfigurableKitOptionForm(forms.ModelForm): """ Форма для добавления варианта (комплекта) к вариативному товару. + Атрибуты варианта выбираются динамически на основе parent_attributes.
