验证组不适用于表单

Question

我正在尝试在我的symfony项目上设置组验证。当我更新实体时，我只需要验证一些字段。当我创建一个实体时，我只需要验证其他一些字段。

服务:

$form = $this->formFactory->createNamed('form', FormType::class, $entity, ['validation_groups' => ['update']]);

形式:

class FormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('user', EntityType::class, [
'class' => User::class,
'validation_groups' => ['create']
])
->add('number', EntityType::class, [
'class' => Numbers::class,
'validation_groups' => ['create', 'update']
])
->add('phone', TextType::class, [
'validation_groups' => ['create', 'update']
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Phones::class,
'allow_extra_fields' => true,
'validation_groups' => ['create', 'update'],
'cascade_validation' => true,
]);
}
}

但是，当我提交表单时，"用户"字段仍然有效。

{"form":{"user":748,"number":"9.2","phone":"0x xx xx xx xx"}}
{"id":957,"error":"Expected argument of type "App\Entity\User", "null" given at property path "user"."}

Answer 1

您不需要在字段上指定validation_groups。默认情况下，传递给表单选项的组将应用于所有字段。

# Service 1
// Only 'create' group will be validated
$this->formFactory->createNamed('form', FormType::class, $entity, ['validation_groups' => ['create']]);
# Service 2
// Only 'create' and 'update' group will be validated
$this->formFactory->createNamed('form', FormType::class, $entity, ['validation_groups' => ['create', 'update']]);
# Form
class FormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('user', EntityType::class, [
'class' => User::class,
// 'validation_groups' => ['create']
])
->add('number', EntityType::class, [
'class' => Numbers::class,
// 'validation_groups' => ['create', 'update']
])
->add('phone', TextType::class, [
// 'validation_groups' => ['create', 'update']
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Phones::class,
'allow_extra_fields' => true,
// 'validation_groups' => ['create', 'update'],
'cascade_validation' => true,
]);
}
}

然而，这看起来不像表单验证错误(违规)。Expected argument of type "App\Entity\User", "null" given at property path "user"表示，传递到'user'字段的值为空(未设置)。当"user"字段用于"创建"时，应该省略它。

解决方案1:

// add option 
$resolver->setDefaults([
'data_class' => Phones::class,
// ...
'addUserField' => null,
]);
// in service pass this option
$this->formFactory->createNamed('form', FormType::class, $entity, [
'validation_groups' => ['create'],
'addUserField' => true
]);
// use condition in form to add field only if option is passed with true value
if($options['addUserField'] === true) {
$builder->add('user', EntityType::class, [class' => User::class]);
}
$builder
->add('number'/** ... */)
->add('phone'/** ... */)
;

解决方案2:

创建2个表单类型FormTypeCreate和FormTypeUpdate。跳过FormTypeUpdate中的"user"字段。也可以从FormTypeUpdate扩展FormTypeCreate。

class FormTypeUpdate extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('number', EntityType::class, [
'class' => Numbers::class,
])
->add('phone', TextType::class)
;
}
//...
}
//
class FormTypeCreate extends FormTypeUpdate
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('user', EntityType::class, [
'class' => User::class,
])
parent::buildForm($builder, $options); // adds 'number' and 'phone' fields
}
//...
}
