Symfony2 FormType Dependency Injection - symfony

Question

I have used DI in Controller, Repository. All repository extend with BaseRepository. But when using a FormType gives the error.
Error Message:
ContextErrorException: Catchable Fatal Error: Argument 2 passed to Personal\SiteBundle\Repository\BaseRepository::__construct() must be an instance of Memcache, instance of Doctrine\ORM\Mapping\ClassMetadata given, called in /home/personal/www/vendor/doctrine/orm/lib/Doctrine/ORM/Repository/DefaultRepositoryFactory.php on line 75 and defined in /home/personal/www/src/Personal/SiteBundle/Repository/BaseRepository.php line 22
How do I think? Structure as follows
AdminBundle/services.yml
personaladmin.towncontroller:

arguments: ["#personalsite.townrepository", "#doctrine.orm.entity_manager", "#personalsite.townformtype"]

Thanks for your help.

Answer 1

So your BaseRepository needs to extend DoctrineReposotory. Doctrine creates repositories using a factory getRepository method. There is no easy way to coax it to pass memcache along. Instead we need to use setter injection.
use Doctrine\ORM\EntityRepository;
class BaseRepository extends EntityRepository
{
// No constructor needed
// Setter injection
setMemcachedProvider(Memcache $memcachedProvider)
{
$this->_memcacheProvider = $memcachedProvider;
}
In your services.yml file get rid of the BaseRepository services and then edit your repository services:
personalsite.cityrepository:
class: Personal\SiteBundle\Repository\CityRepository
factory_service: 'doctrine.orm.default_entity_manager'
factory_method: 'getRepository'
arguments:
- 'Personal\SiteBundle\Entity\City'
calls:
- [setMemcachedProvider, ['#memcache']]
That should do the trick.
I am a little bit curious as to why you are injecting memcache. I am assuming you have some custom repository code that uses it? Doctrine will ignore it. If you are trying to configure Doctrine to use memcache then that is a different process altogether.
