Error when targetEntity is in a different bundle

Question

I'm getting the following error when I try to do `./app/console doctrine:migrate:diff`: ``` [Doctrine\ORM\Mapping\MappingException] Class VNN\CoreBundle\Entity\Game is not a valid entity or mapped super class. ``` Here's the line that's causing it: ``` /** * @ORM\ManyToOne(targetEntity="VNN\CoreBundle\Entity\Game") ``` Here's the relevant part of my class: ``` <?php namespace VNN\PressboxBundle\Entity; use Gedmo\Mapping\Annotation as Gedmo; use Doctrine\ORM\Mapping as ORM; use Doctrine\ORM\Query\Expr\OrderBy; use Symfony\Component\Validator\Constraints as Assert; use Symfony\Component\Validator\Mapping\ClassMetadata; use Symfony\Component\Validator\Constraints\NotBlank; use Symfony\Component\Validator\Constraints\Type; use VNN\CoreBundle\Entity\Game; /** * VNN\PressboxBundle\Entity\Event * * @ORM\Table(name="event") * @ORM\Entity */ class Event { /** * @var integer $id * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @OR…

Accepted Answer

i've successfully used cross bundle entity relations without any problems. if you have automatic mapping disabled you need to tell doctrine each bundle that contains entities.

so in app/config.yml you need to have either this:

```
doctrine:
    orm:
        auto_mapping: true
```

or this:

```
doctrine:
    orm:
        auto_mapping: false
        entity_managers:
            default:
                mappings:
                    VNNCoreBundle: ~
                    VNNPressboxBundle: ~
```

check your database if tables for the bundles exist. also you could try running `./app/console doctrine:generate:entities --force` and make sure it runs without errors

edit

i checked my code and the leading `/` is not necessary. also the `use` statement is superfluous.
