奏鸣曲和Gedmo\Reference原则扩展不起作用（Class不存在） [英] Sonata and Gedmo\References doctrine extension doesn't work ( Class does not exist )

问题描述

我想链接原则orm实体和原则odm文件，并在管理类的configureFormFields方法中的sonataAdminBundle中使用它们。

我已经建立了@Gedmo \Reference doctrine-extension，当我尝试从控制器访问链接的模型时，它的工作正常。

但现在我需要从SonataAdminBundle - 创建一个UI，将链接的文档添加到用户实体。

这是我的实体：

 <？php

使用Doctrine\ORM\Mapping作为ORM; 
使用Sonata\UserBundle\Entity\BaseUser; 
使用FOS\UserBundle\Model\GroupInterface; 
使用Sonata\UserBundle\Model\UserInterface; 
使用Gedmo\Mapping\Annotation作为Gedmo; 
使用Application\Sonata\UserBundle\Document\Address;

这里是我的configureFormFields方法：

  protected function configureFormFields（FormMapper $ formMapper）
 {
 $ formMapper 
  - > with（'General' ）
  - > add（'addresses'，'sonata_type_model'，array（
'required'=> false，
'expanded'=> true，
'multiple '=> true 
））
  - > end（）; 
} 
  

它说：
类不存在

我也试过sonata_type_collection，但也是一个错误：

   - >添加（'addresses'，'sonata_type_collection'，array（
 //防止显示Delete选项
'type_options'=> array（'delete'=> false）
 ），array（
'edit'=>'inline'，
'inline'=>'table'，
'sortable'=>'position'，
 ））
  

当前字段地址不是链接到管理员。请为目标实体创建一个：``

我应该使用哪些sonata_form_type来使一切正常？

解决方案

我遇到了同样的问题@ArFeRR。我的解决方案是使用实体类型，并为表单域添加相关的类名：

  protected function configureFormFields（FormMapper $ formMapper 
 {
 $ formMapper 
 //  - > add（'branch'，'sonata_type_model'，array（// Unknown Document namespace alias'PlusquamContractBundle'。
  - > add（'branch'，'entity'，array（
'class'=>'PlusquamContractBundle：Branch'，
'by_reference'=> false 
））
; 
} 
  

这将使类不存在错误消失。 / p>

I want to link the doctrine orm entity and doctrine odm document and use them in sonataAdminBundle in configureFormFields Method of the Admin Class.

I've established the @Gedmo\References doctrine-extension and it works just fine when i'm trying to access the linked models from controller.

But now I need to do it from SonataAdminBundle - to make an UI to add the linked documents to the user entity.

Here is my entity:

Here is my configureFormFields Method:

    protected function configureFormFields(FormMapper $formMapper)
    {
    $formMapper
        ->with('General')
        ->add('addresses', 'sonata_type_model', array(
                'required' => false,
                'expanded' => true,
                'multiple' => true
            ))
        ->end();
    }

it says: Class does not exist

i tried the sonata_type_collection too, but it's an error too:

         ->add('addresses', 'sonata_type_collection', array(
                // Prevents the "Delete" option from being displayed
                'type_options' => array('delete' => false)
            ), array(
                'edit' => 'inline',
                'inline' => 'table',
                'sortable' => 'position',
            ))

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

What sonata_form_type should I use to make everything work???

解决方案

I ran into the same issue @ArFeRR. My solution was to use the 'entity' type and add the related class name for the form field:

    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
//            ->add('branch', 'sonata_type_model', array( // Unknown Document namespace alias 'PlusquamContractBundle'.
            ->add('branch', 'entity', array(
                'class'    => 'PlusquamContractBundle:Branch',
                'by_reference' => false
            ))
        ;
    }

This will make the "Class does not exist" error disappear.
