17/11/2015 - DOCTRINE, MONGODB, SYMFONY
This example depends on two documents (one League can have one Team embedded) for EmbedOne and shows us how to use MongoDB as database for our application. For more info visit DoctrineMongoDBBundle, QueryBuilder API, Embedded Mapping, Annotations Reference and Working with Objects.
services:
application_nosql.controller.default:
class: Application\NosqlBundle\Controller\DefaultController
arguments:
- @doctrine_mongodb.odm.default_document_manager
- @application_nosql.repository.league
services:
application_nosql.repository.league:
class: Application\NosqlBundle\Repository\DefaultRepository
factory: [@doctrine_mongodb, getRepository]
arguments: [Application\NosqlBundle\Document\League]
For now, I've just kept all in controller below but in real life, you should use service, model and factory classes along with controller to divide the logic.
