Sonataadminbundle: Unable to use the sonata_type_admin field - Field not linked to an admin

[aguidis]

I have an entity "Author" and "Image" with a simple OneToOne relation.
I tried to embed an Admin class in my Author admin class for the "image" field which is linked to the Image entity.

The mapping betweens the two classes is correct.

I created an Admin class for each entity :

• ImageAdmin works correctly. When I add a new image, the database is updated and the image is uploaded.
• Then I create the AuthorAdmin thanks to the documentation (http://sonata-project.org/bundles/admin/master/doc/reference/form_types.html#sonata-type-admin). But I always have this message :

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

The admin services are registred in the admin.yml (I used http://sonata-project.org/bundles/admin/master/doc/reference/form_types.html#sonata-type-admin) :

services:
    sonata.admin.author:
        class: Project\BackendBundle\Admin\AuthorAdmin
        tags:
            - { name: sonata.admin, manager_type: orm, group: "Content", label: "Author" }
        arguments:
            - ~
            - Project\BackendBundle\Entity\Author
            - ~

    sonata.admin.image:
        class: Project\BackendBundle\Admin\ImageAdmin
        tags:
            - { name: sonata.admin, manager_type: orm, group: "Content", label: "Image" }
        arguments:
            - ~
            - Project\BackendBundle\Entity\Image
            - 'SonataAdminBundle:CRUD'

I followed all the documentation but now I don't see the problem. I even try to pass the FieldDescription option "admin_code" :

$formMapper
    ->add('name', 'text', array('label' => 'Author name'))
    ->add(
        'image',
        'sonata_type_admin',
        array(),
        array('admin_code' => 'sonata.admin.image')
    )
;

I use the lastest version of sonata admin bundle sonata-project/admin-bundle.

[aguidis]

@ORM\Column overrides @ORM\OneToOne and Doctrine sees this field as simple field - not as association. I just had to remove the line.

[j-ledoux]

Hey guys,

I'd like to reopen this issue as it is happening with the latest stable version of Sonata, without @ORM\Column annotation.
I currently have following version for my project :

• sonata-project/admin-bundle 3.4.0
• sonata-project/block-bundle 3.1.1
• sonata-project/core-bundle 3.0.3
• doctrine/orm 2.5.4
• symfony/symfony 3.0.8

I have the same error message when I try to use sonata_type_admin with all my admin forms.

Here is an example : I 'm trying to include a Company admin form in a Contact

Here are my 2 entities relations parts :

/**
 * Contact
 *
 * @ORM\Table(name="contact")
 * @ORM\Entity
 */
class Contact
{
    /**
     * @ORM\ManyToOne(targetEntity="Project\UserBundle\Entity\Company", inversedBy="contacts")
     * @ORM\JoinColumn(name="company_id", referencedColumnName="id")
     * @Assert\NotNull
     */
    protected $company;
}

/**
 * Company
 *
 * @ORM\Table(name="company")
 * @ORM\Entity
 */
class Company
{
    /**
     * @ORM\OneToMany(targetEntity="Project\UserBundle\Entity\Contact", mappedBy="company")
     */
    protected $contacts;
}

Services :

    project_user.admin.company:
        class: Project\UserBundle\Admin\CompanyAdmin
        arguments: [~, Project\UserBundle\Entity\Company, 'SonataAdminBundle:CRUD']
        tags:
            - {name: sonata.admin, manager_type: orm, label: Company}
        calls:
            - [ setTranslationDomain, ['ProjectModelAdmin']]

    project_user.admin.contact:
        class: Project\UserBundle\Admin\ContactAdmin
        arguments: [~, Project\UserBundle\Entity\Contact, ProjectUserBundle:ContactAdmin]
        tags:
            - {name: sonata.admin, manager_type: orm, label: Contact}
        calls:
            - [ setTranslationDomain, ['ProjectModelAdmin']]

In ContactAdmin class :

$formMapper
    ->add('company', 'sonata_type_admin',
        array(
            'required'   => true,
            'btn_add'    => false,
            'btn_delete' => false,
        ),
        array(
            'admin_code' => 'project_user.admin.company',
        )
    )
;

Both admin class works well separately, but with company as a sonata_type_admin (as well as my other admin classes) It shows up the following error message :

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

[greg0ire]

Please create one for the target entity

Can you give a full stack trace?

[j-ledoux]

Sure here it is (I replaced some namespaces by 'project' in my previous example)

[greg0ire]

I think you should debug this method, it is responsible for doing this link I think.

[j-ledoux]

Thanks I'm gonna check it out

[j-ledoux]

It seems that the method attachAdminClass is not called during the process

[greg0ire]

This sounds oddly familiar… are you using the latest version of the doctrine orm admin bundle ?

[greg0ire]

You should debug this line now : https://github.com/sonata-project/SonataDoctrineORMAdminBundle/blob/55d1f169af953cbf4c9c2933f2f0734652613561/Builder/FormContractor.php#L68

[j-ledoux]

Yes I have the latest stable version :
sonata-project/doctrine-orm-admin-bundle 3.0.5

[greg0ire]

In your case, it would look more like this : https://github.com/sonata-project/SonataDoctrineORMAdminBundle/blob/3.0.5/Builder/FormContractor.php#L68

[j-ledoux]

Thanks.
In the case of the company field the method getMappingTypereturns NULL instead of ClassMetadataInfo::MANY_TO_ONE's value

[greg0ire]

Where/when is the mappingType supposed to be set?

[j-ledoux]

I have no idea, I can't find any calls to the method setMappingType in my bundles

[j-ledoux]

I've switched to sonata-project/doctrine-orm-admin-bundle dev-master 3bc573b, now I have a different error :

You are trying to add sonata_type_admin field company which is not One-To-One or Many-To-One. Maybe you want sonata_model_list instead?

[greg0ire]

Huh… interesting.

[greg0ire]

Anyway, dev-master is future Sonata 4, so… don't use it. If you want to try something, try 3.x instead.

[greg0ire]

Also, the error message makes a lot of sense, doesn't it? or does it? Isn't your relation many to one?

[j-ledoux]

I'm trying 3.x-dev f7e221d, same error message than dev-master.
Well the error message would make sense if I hadn't a @ORM\ManyToOnerelationship to the field company...

[greg0ire]

Yes I got confused. Can you try the \Exception trick? It should get you a stack trace showing where setMappingType is supposed to be called.

[j-ledoux]

Found it at https://github.com/sonata-project/SonataDoctrineORMAdminBundle/blob/3.x/Model/ModelManager.php#L142
The weird part is that company field is not in Doctrine\ORM\Mapping\ClassMetadata associationMappings array nor in fieldMappings array.
I'm starting to think It might be a Doctrine Issue...

[greg0ire]

Uuuuh this is setFieldMapping, not setMappingType.

[j-ledoux]

Wooops my bad, I'm getting tired.

Exception in method setMappingType in BaseFieldDescription is never thrown even after I've emptied cache.

[greg0ire]

Exception in method setMappingType in BaseFieldDescription is never thrown even after I've emptied cache.

Even when going on another form with a relation that works?

[j-ledoux]

Indeed

[j-ledoux]

Currently I'm using SF EntityType field, which is working fine

$formMapper->add('company', 'entity', array(
    'class'        => 'ThecampUserBundle:Company',
    'expanded'     => false,
    'required'     => true,
    'placeholder'  => $container->get('translator')->trans('Choose a company', array(), 'ThecampModelAdmin'),
))

But I'd rather use sonata_type_admin in order to have the add/delete buttons.

[greg0ire]

I have a project with Sonata 2 and sonata_type_admin. I'm currently migrating it to php7 but I should be done soon. I'll try the exception trick if you haven't found anything until then.

[j-ledoux]

Thanks for your help anyway @greg0ire

[j-ledoux]

For information, the exact same issue occurs with sonata_type_model_autocomplete, sonata_type_collection in a create form. But when editing an existing entity, sonata_type_admin works fine, and the others two (sonata_type_model_autocomplete, sonata_type_collection) give different errors.

[greg0ire]

Ok so I tried on a form where I have this, and no setMappingType call whatsoever.

[greg0ire]

But the mapping type is not null in my case…

[greg0ire]

It is set by calling Sonata\DoctrineORMAdminBundle\Admin\FieldDescription::setAssociationMapping()

[greg0ire]

Which should happen here in your case. This is what you need to debug.

[j-ledoux]

Weird, cause $metadata->associationMappings is empty in my case...

[greg0ire]

Can you dump the whole $metadata (remove all fields but company before doing that, it should help your debugging, let's not get confused with other fields)?

[j-ledoux]

Realy weird : when I dump $metadata from a contact create form this is not my Contact entity but my User entity metadata... which is not related to Contact entity at all

[greg0ire]

Is your ContactAdmin associated with the right class?

[j-ledoux]

Shame on me !!! I forgot an old statement in configureFormFields when I had inheritance from User entity :

if (!$subject->getId()) {
    $user = $userManager->createUser();
    $this->setSubject($user);
}

Of course sonata_type_admin and sonata_type_model seems to work much better now...
Thanks @greg0ire to point me in the right direction. Sorry for wasted your time mate.

[greg0ire]

Sorry for wasted your time mate.

If you want to repay me, make a PR that checks the type of $subject against $this->class ;) Should be very very easy.

[j-ledoux]

That would have save my day indeed, I'll look into it.
