## Your Approach

- **Data Model First**: Design comprehensive DataObject classes before implementation - the data model drives the entire application
- **Symfony Best Practices**: Follow Symfony conventions for controllers, services, events, and configuration
- **E-Commerce Integration**: Leverage Pimcore's E-Commerce Framework rather than building custom solutions
- **Performance Optimization**: Use lazy loading, optimize queries, implement caching strategies, and leverage Pimcore's indexing
- **Content Reusability**: Design areabricks and snippets for maximum reusability across documents

- **Workflow-Driven**: Implement workflows for content approval, product lifecycle, and asset management processes
- **Multi-language Support**: Design for internationalization from the start with proper locale handling

## Guidelines

### Project Structure

- Follow Pimcore's directory structure with `src/` for custom code
- Organize controllers in `src/Controller/` extending Pimcore's base controllers
- Place custom models in `src/Model/` extending Pimcore DataObjects
- Store custom services in `src/Services/` with proper dependency injection
- Create areabricks in `src/Document/Areabrick/` implementing `AbstractAreabrick`
- Place event listeners in `src/EventListener/` or `src/EventSubscriber/`
- Store templates in `templates/` following Twig naming conventions
- Keep DataObject class definitions in `var/classes/DataObject/`

### DataObject Classes

- Define DataObject classes through the admin interface at Settings → DataObjects → Classes
- Use appropriate field types: input, textarea, numeric, select, multiselect, objects, objectbricks, fieldcollections
- Configure proper data types: varchar, int, float, datetime, boolean, relation
- Enable inheritance where parent-child relationships make sense
- Use object bricks for optional grouped fields that apply to specific contexts
- Apply field collections for repeatable grouped data structures
- Implement calculated values for derived data that shouldn't be stored
- Create variants for products with different attributes (color, size, etc.)
- Always extend generated DataObject classes in `src/Model/` for custom methods

### E-Commerce Development

- Extend `\Pimcore\Model\DataObject\AbstractProduct` or implement `\Pimcore\Bundle\EcommerceFrameworkBundle\Model\ProductInterface`
- Configure product index service in `config/ecommerce/` for search and filtering
- Use `FilterDefinition` objects for configurable product filters
- Implement `ICheckoutManager` for custom checkout workflows
- Create custom pricing rules through admin or programmatically
- Configure payment providers in `config/packages/` following bundle conventions
- Use Pimcore's cart system rather than building custom solutions
- Implement order management through `OnlineShopOrder` objects
- Configure tracking manager for analytics integration (Google Analytics, Matomo)
- Create vouchers and promotions through admin or API

### Areabrick Development

- Extend `AbstractAreabrick` for all custom content blocks
- Implement `getName()`, `getDescription()`, and `getIcon()` methods
- Use `Pimcore\Model\Document\Editable` types in templates: input, textarea, wysiwyg, image, video, select, link, snippet
- Configure editables in templates: `{{ pimcore_input('headline') }}`, `{{ pimcore_wysiwyg('content') }}`
- Apply proper namespacing: `{{ pimcore_input('headline', {class: 'form-control'}) }}`
- Implement `action()` method for complex logic before rendering
- Create configurable areabricks with dialog windows for settings
- Use `hasTemplate()` and `getTemplate()` for custom template paths

### Controller Development

- Extend `Pimcore\Controller\FrontendController` for public-facing controllers
- Use Symfony routing annotations: `#[Route('/shop/products', name: 'shop_products')]`
- Leverage route parameters and automatic DataObject injection: `#[Route('/product/{product}')]`
- Apply proper HTTP methods: GET for reads, POST for creates, PUT/PATCH for updates, DELETE for deletions
- Use `$this->renderTemplate()` for rendering with document integration
- Access current document: `$this->document` in controller context
- Implement proper error handling with appropriate HTTP status codes
- Use dependency injection for services, repositories, and factories
- Apply proper authorization checks before sensitive operations

### Asset Management

- Organize assets in folders with clear hierarchical structure
- Use asset metadata for searchability and organization
- Configure thumbnail configurations in Settings → Thumbnails
- Generate thumbnails: `$asset->getThumbnail('my-thumbnail')`
- Process videos with Pimcore's video processing pipeline
- Implement custom asset types when needed
- Use asset dependencies to track usage across the system
- Apply proper permissions for asset access control
- Implement DAM workflows for approval processes

### Multi-Language & Localization

- Configure locales in Settings → System Settings → Localization & Internationalization
- Use language-aware field types: input, textarea, wysiwyg with localized option enabled
- Access localized properties: `$object->getName('en')`, `$object->getName('de')`
- Implement locale detection and switching in controllers
- Create document trees per language or use same tree with translations
- Use Symfony's translation component for static text: `{% trans %}Welcome{% endtrans %}`
- Configure fallback languages for content inheritance
- Implement proper URL structure for multi-language sites

### REST API & Data Hub

- Enable Data Hub bundle and configure endpoints through admin interface
- Create GraphQL schemas for flexible data queries
- Implement REST endpoints by extending API controllers
- Use API keys for authentication and authorization
- Configure CORS settings for cross-origin requests
- Implement proper rate limiting for public APIs
- Use Pimcore's built-in serialization or create custom serializers
- Version APIs through URL prefixes: `/api/v1/products`

### Workflow Configuration

- Define workflows in `config/workflows.yaml` or through admin interface
- Configure states, transitions, and permissions
- Implement workflow subscribers for custom logic on transitions
- Use workflow places for approval stages (draft, review, approved, published)
- Apply guards for conditional transitions
- Send notifications on workflow state changes
- Display workflow status in admin interface and custom dashboards

### Testing

- Write functional tests in `tests/` extending Pimcore test cases

## Best Practices Summary

1. **Model First**: Design DataObject classes before coding - they are the foundation
2. **Extend, Don't Modify**: Extend generated DataObject classes in `src/Model/`
3. **Use the Framework**: Leverage E-Commerce Framework rather than custom solutions
4. **Proper Namespacing**: Follow PSR-4 autoloading standards
5. **Type Everything**: Use strict typing for all methods and properties
6. **Cache Strategically**: Implement proper caching with cache tags
7. **Optimize Queries**: Use eager loading and proper indexing
8. **Test Thoroughly**: Write tests for critical business logic
9. **Document Configuration**: Comment admin interface configurations in code
10. **Security First**: Use proper permissions and validate all inputs
