SonataAdminBundle, sonata_type_collection and embed forms

Question

Mensaje StackOverflow

Hello everybody!

I'm having a strange issue (cause it was already solved many months ago) regarding SonataAdminBundle. The thing is that my embed forms is not longer working. My approach basically follows this tutorial: http://simonsaysblog.net/sonataadminbundle-doctrine-and-onetomany-relationship (and many other tutorials around the Net).

I have the "User" entity (the one installed by Sonata User Bundle over FOSUserBundle) which has two entities: Email and Phone, in a Many-to-One relationship with User (One user has many email addresses and many phone numbers).

Call the User form display this error message:

The current field `emails` is not linked to an admin. Please create one for the target entity : ``

(The entity name is blank as you can notice).

admin.xml

    <service id="myapp.my_bundle.admin.email" class="MyApp\MyBundle\Admin\EmailAdmin">
        <tag name="sonata.admin" manager_type="orm" group="Configuration" label="Emails" />
        <tag name="security.secure_service" />
        <argument />
        <argument>MyApp\MyBundle\Entity\Email</argument>
        <argument>MyAppMyBundle:EmailAdmin</argument>
    </service>

    <service id="myapp.my_bundle.admin.phone" class="MyApp\MyBundle\Admin\PhoneAdmin">
        <tag name="sonata.admin" manager_type="orm" group="Configuration" label="Phones" />
        <tag name="security.secure_service" />
        <argument />
        <argument>MyApp\MyBundle\Entity\Phone</argument>
        <argument>MyAppMyBundle:PhoneAdmin</argument>
    </service>

The only one thing I could think it has changed is the location of all the Sonata User files. Before they were locatated into MyApp\\MyBundle , now they are now into Application\\Sonata\\UserAdmin\\ folder (as is showed in the Sonata Project documentation).

If I take off the add() method, in the UserAdmin class, corresponding to email, the form renders OK (very slowly, but it renders OK).

Answer 1

如果我对消息很了解，则必须为MyApp\\MyBundle\\Entity\\Email和MyApp\\MyBundle\\Entity\\Phone实体定义另外两个管理类（以便在UserAdmin类sonata_type_collection它们链接为sonata_type_collection ）。
