我正在尝试在其他表单类型中添加 formType。
客户类型：
class CustomerType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('firstname', 'text', array(
'required' => 'required'
))
->add('middlename')
->add('lastname')
->add('email', 'email')
->add('groups', 'entity', array(
'class' => 'MV'CMSBundle'Entity'Group',
'property' => 'name',
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('g')
->orderBy('g.name', 'ASC');
}
))
->add('profile', 'collection', array(
'type' => new ProfileType()
));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'MV'CMSBundle'Entity'User',
));
}
public function getName()
{
return 'customer';
}
}
配置文件类型：
class ProfileType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('isActive', 'checkbox', array(
'required' => false
))
->add('phone')
->add('address')
->add('city')
->add('zipcode')
->add('country')
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'MV'NameBundle'Entity'Profile',
));
}
public function getName()
{
return 'profile';
}
}
然后我收到这条消息：
Expected argument of type "array or ('Traversable and 'ArrayAccess)", "MV'NameBundle'Entity'Profile" given.
如果我评论那行，我会得到：（只是为了检查;)会出错）
The form's view data is expected to be of type scalar, array or an instance of 'ArrayAccess, but is an instance of class MV'NameBundle'Entity'Profile. You can avoid this error by setting the "data_class" option to "MV'NameBundle'Entity'Profile" or by adding a view transformer that transforms an instance of class MV'NameBundle'Entity'Profile to scalar, array or an instance of 'ArrayAccess.
我做错了什么？
Symfony2： 2.1.8-DEV
目前尚不清楚您的Customer实体和Profile实体之间的映射是什么，但我想有 2 个选项：
选项 1：您有一对一关系（一个客户只能有一个配置文件）。因此，您根本不需要集合，而只需要嵌入单个对象。
->add('profile', new ProfileType());
选项 2：您想要多对一关系（一个客户可以有多个配置文件）。在这种情况下，您需要使用 嵌入表单集合。如果这是您想要的，请在您的客户实体中将$profile重命名为$profiles，然后执行以下操作：
//MV'CMSBundle'Entity'Customer
use Doctrine'Common'Collections'ArrayCollection;
/**
* Your mapping here.
*
* @ORM'ManyToOne(targetEntity="MV'NameBundle'Entity'Profile")
*/
protected $profiles;
public function __construct()
{
//This is why you had an error, this is missing from your entity
//An object was sent instead of a collection.
$this->profiles = new ArrayCollection();
}
最后，更新数据库。
