+description: Prevents the common error of using invalid Doctrine ORM attributes
+  in Repository classes
+---
+
+When creating Doctrine repositories, NEVER use #[ORM\EntityManager] as this is not a valid Doctrine mapping attribute and causes runtime errors. Repositories must only be instantiated via Dependency Injection with EntityManagerInterface in their constructor. Valid ORM attributes for Repositories include: none (standard), or optionally #[ORM\HasEntityListeners] if needed. Mapping attributes like #[ORM\Entity], #[ORM\Table], #[ORM\JoinColumn] are ONLY for Entity classes, not Repository classes.

+description: Ensures minimal boilerplate by avoiding unnecessary custom
+  Repository classes for standard CRUD operations, while still allowing them for
+  complex queries.
+alwaysApply: true
+---
+
+In Symfony and Doctrine based applications, avoid creating custom Repository classes for simple CRUD or standard query operations (e.g., findOneBy, findBy). Instead, use Doctrine's native EntityRepository directly via $entityManager->getRepository(Entity::class) within the Provider or Processor implementations.
+
+Only create a custom repository when:
+1. Complex queries involving multiple joins, subselects, or specialized search logic are required.
+2. Query logic is reused across multiple Providers/Processors and warrants encapsulation for DRY compliance.
+
+When no custom repository is needed, Inject EntityManagerInterface directly into the Provider or Processor and fetch the repository inline as shown below:
+
+```php
+$repository = $this->entityManager->getRepository(EntityClass::class);
+$result = $repository->findOneBy(['id' => $id]);
+```
+
+Do not create an empty or wrapper Repository class that only delegates to Doctrine's native methods.
