How to define/pass the entity manager for sonata-admin

Question

I followed this tutorial to install SonataAdmin with FOSUserBundle.

Now i keep getting this Error Message: No entity manager defined for class Application\Sonata\UserBundle\Entity\User

But how do i set/pass the EntityManager? I haven't found anything about configuring it or any hint on what this error means. Any help anyone?

Edit #1:

As asked for, here is what i have in my config.yml for sonata so far:

sonata_block:
    default_contexts: [cms]
    blocks:
        sonata.admin.block.admin_list:
            contexts:   [admin]
        sonata.block.service.text:
        sonata.block.service.rss:

Edit #2:

I added the entity manager configuration part for Doctrine2 ORM Admin thou it is mentioned in the Documentation that if left null, it should just use the default. Still, it doesn't solve my problem.

sonata_doctrine_orm_admin:
    # default value is null, so doctrine uses the value defined in the configuration
    entity_manager: '@doctrine.orm.entity_manager'

---

Edit #3: I did set auto_mapping to true as well, even thou that also is true by default. Still no Solution to this Problem.

Solution 1

What was missing in my config.yml was:

doctrine:
  [...]
  orm:
    [...]
    entity_managers:
      default:
        mappings:
          ApplicationSonataUserBundle: ~
          SonataUserBundle: ~

Solution 2

When you use php app/console sonata:admin:generate it requests for fully qualified model class, so you'd write something like: \Acme\DemoBundle\Entity\DemoEntity

the problem is, that when generator creates service for you it adds line: arguments: [~, \Acme\DemoBundle\Entity\DemoEntity, AcmeDemoBundle:DemoEntityAdmin]

That breaks it.

It works with: arguments: [~, Acme\DemoBundle\Entity\DemoEntity, AcmeDemoBundle:DemoEntityAdmin]

Notice missing "\" before Acme\Demo....

Solution 3

Just had this problem.

Make sure you easy-extended the SonataUserBundle:

php app/console sonata:easy-extends:generate SonataUserBundle

and are loading it in AppKernel.php

new Application\Sonata\UserBundle\ApplicationSonataUserBundle(),

See documentation here: https://github.com/sonata-project/SonataUserBundle/blob/master/Resources/doc/reference/installation.rst

Then the automapping is enough and you don't need to define manual mapping.
