如何在嵌入另一个表单的Symfony表单上设置默认值？

How does one set the default form value of a Symfony form embedded within another form that are both associated with entities?

如何设置嵌入在另一个表单中的Symfony表单的默认表单值，这些表单都与实体相关联？

If I try to set the street property in my PropertyLocation entity to a default value in the following example, this default value does not get shown when the form renders. I know there is a data option for each form field that I could use, but I would rather not do it this way since that overrides what is set in the entity. How can I make the form show the default value stored in the entity.

如果我尝试在我的PropertyLocation实体中将street属性设置为以下示例中的默认值，则在表单呈现时不会显示此默认值。我知道我可以使用每个表单字段的数据选项，但我不想这样做，因为它会覆盖实体中设置的内容。如何使表单显示存储在实体中的默认值。

class PropertyType
{

     /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('propertyLocation', new PropertyLocationType());
    }

    /**
     * @param OptionsResolverInterface $resolver
     */
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(
             array('data_class' => 'UR\AppBundle\Entity\Property'
        ));
    }

    /**
     * @return string
     */
    public function getName()
    {
        return 'property';
    }
}

Property Location Type looks like:

物业位置类型看起来像：

class PropertyLocationType extends AbstractType 
{

    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('street', 'text');
    }

   /**
    * @param OptionsResolverInterface $resolver
    */
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
        'data_class' => 'UR\AppBundle\Entity\PropertyLocation'
        ));
    }

   /**
    * @return string
    */
    public function getName()
    {
        return 'propertyLocation';
    }
 }

Default values could be set in the newAction within your controller :

可以在控制器的newAction中设置默认值：

Let's say that you have a PropertyController.php as a controller for your Property entity

假设您有一个PropertyController.php作为Property实体的控制器

Your newAction will look like this :

你的newAction将如下所示：

public function newAction()
{
    $defaultPropertyLocation = new  PropertyLocation();
    $defaultPropertyLocation->setStreet('default value ');
    $property = new Property();
    $property->setPropertyLocation($defaultPropertyLocation);
    // now you could pass your property entity to get rendred
    $form   = $this->createCreateForm($property);

    return $this->render('YourBundle:Property:new.html.twig', array(
        'entity' => $property,
        'form'   => $form->createView(),
    ));
}

Edit Second option : use data field

编辑第二个选项：使用数据字段

->add('myfield', 'text', array(
     'label' => 'Field',
     'data' => 'Default value'
))

AFAIK There is no third option.

AFAIK没有第三种选择。
