Symfony 2表格编辑使用空的依赖字段

我有一个问题，使我的表单编辑在我的crud中，我使用命令从symfony 2.8创建crud，在检查编辑视图时，它加载了记录的所有字段我搜索了，但是另一个实体的依赖字段出现空白(现场货物，专业，ROL，Dectionamento(。我想知道如何通过各自的信息出现依赖性字段。

这是我的datusuariotype

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('username',TextType::class, array('attr'=>array('class'=>'form-control col-xs-10 col-sm-5', 'style' => 'margin-bottom:10px'),'label'=>'Usuario'))
            ->add('password',PasswordType::class, array('attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px')))
            ->add('nombre',TextType::class, array('attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px')))
            ->add('paterno',TextType::class, array('attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'label'=>'Apellido Paterno'))
            ->add('materno',TextType::class, array('attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'label'=>'Apellido Materno'))
            ->add('ci',TextType::class, array('attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'label'=>'Carnet de Identidad'))
            ->add('departamento',EntityType::class, array('class'=>'bdBundle:ClaDepartamento','label'=>'Departamento', 'attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'data' => '$id', 'placeholder' => 'Escoge una Opcion',))
            ->add('fechaNac',DateType::class, array('widget'=>'single_text', 'html5' => false, 'input' => 'datetime','label'=>'Fecha de Nacimiento','format'=>'dd/MM/yyyy', 'attr'=> ['class'=>'form-control js-datepicker', 'style' => 'margin-bottom:10px','placeholder'=>'dd/mm/yyyy', 'readonly'=>true]))
            ->add('telefono',TextType::class, array('attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'label'=>'Telefono Fijo'))
            ->add('celular',TextType::class, array('attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'label'=>'Telefono Celular'))
            ->add('email',EmailType::class, array('attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'label'=>'Correo Electronico'))
            ->add('rol',EntityType::class, array('class'=>'bdBundle:DatRol','label'=>'Rol de Usuario', 'attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'data' => '$id', 'placeholder' => 'Escoge una Opcion',))
            ->add('cargoUsuario',EntityType::class, array('class'=>'bdBundle:DatCargoUsuario','label'=>'Cargo de Usuario', 'attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'data' => '$id', 'placeholder' => 'Escoge una Opcion',))
            ->add('profesion',EntityType::class, array('class'=>'bdBundle:ClaProfesion','label'=>'Profesion de Usuario', 'attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'data' => '$id', 'placeholder' => 'Escoge una Opcion',))
            ->add('imagen',TextType::class, array('attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'label'=>'Foto de Perfil'))
            ->add('estado',ChoiceType::class, array('choices'=>array(true=> 'Habilitado'),'attr'=>array('class'=>'form-control', 'style' => 'margin-bottom:10px'),'label'=>'Activo / Inactivo'));

}

这是我的控制器datusuariocontroller

public function editAction(Request $request, DatUsuario $datUsuario)
{
    $deleteForm = $this->createDeleteForm($datUsuario);
    $editForm = $this->createForm('gishaybdBundleFormDatUsuarioType', $datUsuario);
    $editForm->handleRequest($request);
    if ($editForm->isSubmitted() && $editForm->isValid()) {
        $this->getDoctrine()->getManager()->flush();
        return $this->redirectToRoute('usuario_edit', array('id' => $datUsuario->getId()));
    }
    return $this->render('datusuario/edit.html.twig', array(
        'datUsuario' => $datUsuario,
        'edit_form' => $editForm->createView(),
        'delete_form' => $deleteForm->createView(),
    ));
}

这是我视图edit.html.twig

的一部分

任何人都可以帮我..：(

sry ...这是我在yml datusuario中的ORM

这是我的datrol

gishaybdBundleEntityDatRol:
type: entity
table: dat_rol
id:
    id:
        type: integer
        nullable: false
        unsigned: true

        generator:
            strategy: IDENTITY

        nullable: false
        length: 50
        fixed: false
    abreviacion:
        type: string
        nullable: true
        length: 50
        fixed: false
    estado:
        type: boolean
        nullable: true
oneToMany:
    DatUsuario:
      targetEntity: DatUsuario
      mappedBy: rol
      fetch: EXTRA_LAZY
lifecycleCallbacks: {  }

感谢您再次回答，...但是在我的编辑表格中，继续字段rol，Profesion等...是空的选择...我再次需要选择...我尝试了Datrol上课...其他人还没有...我需要在字段中选择此选择数据库的数据... thanx

好的，现在我知道了。

您的所有关系都是单向的，因为您有mappedBy: null和inversedBy: null这就是为什么Symfony认为您会设置Manualy，例如

// manual relations
$datUsuario->setRol( $yourRoleEntity );
$datUsuario->setDepartamento( $yourRoleEntity );
// and so on..
// but I think you don't want that....
// form
$editForm = $this->createForm('gishaybdBundleFormDatUsuarioType', $datUsuario);

也可能发生的事情 - 您只是在DatRol，ClaDepartamento，DatCargoUsuario表中没有任何记录。这就是为什么下拉列表为空的原因...如果是这样，请先添加一些数据！

但是，回到您的关系...

检查这个很好的参考

您可以看到，您应该声明

manyToOne:
    rol:
        targetEntity: DatRol
        cascade: { 'persist' } # Play around with other settings...
        #remove this since it's incorret. you can't have both!
        #mappedBy: null 
        inversedBy: datUsario
        joinColumns:
            rol_id:
                referencedColumnName: id
        orphanRemoval: false
    # do the same for all others manyToOne relations

完成后，转到您的DatRol，ClaDepartamento，DatCargoUsuario和ClaProfesion，然后编辑您的oneToMany关系。删除inversedBy并添加mapeedBy

喜欢：

oneToMany:
    datUsario: 
        targetEntity: DatUsuario
        mappedBy: rol
        fetch: EXTRA_LAZY

在所有其他方面都做同样的事情...

thumb规则：

inversedBy始终在外键所在的一边(manyToMany是例外，有关更多详细信息，请参见ormcheatsheat(
mappedBy在另一侧

有关更多信息，请查看上面的ORMCHEATSHEET，以及Doctrine的一对多，双向
