Form validation ignores empty value
FormType:
class BranchFormType extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder->add('name');
}
public function getName() {
return 'branch';
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'MyMainBundleEntityBranch',
));
}
}
In entity definition:
<field name="name" column="name" type="string" length="255"/>
there is no nullable=true and the field has required attribute when rendered.
Validation.yml:
MyMainBundleEntityBranch:
properties:
name:
- NotBlank: ~
Does symfony find this file automatically or do I have to included somewhere? The doc just states, that the form uses validation service automatically.
Controller:
$branch = new Branch();
$form = $this->createForm(new BranchFormType(), $branch);
if ($request->isMethod('POST')) {
$form->bindRequest($request);
if ($form->isValid()) {
$em->persist($branch);
$em->flush();
return $this->redirect($this->generateUrl('view_branch'));
}
}
return $this->render('MyMainBundle:Branch:create.html.twig', array(
'form' => $form->createView()
));
On submit I get following error:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'name' cannot be null
So isValid returns true dispite the fact that name is empty and continues to persist the entity with empty values. How can isValid return true when name is empty? ORM definition says nullable=false?`Any ideas? I have no extra validator defined. I use sf2.1
It looks like the validation file is in the right folder:
src/My/MainBundle/Resources/config/validation.yml
Make sure you are not using validation groups?
Anyway, I would use Assert
to see if there is something wrong with this validation file:
Enable annotations:
# app/config/config.yml
framework:
validation: { enable_annotations: true }
Set up your entity:
namespace MyMainBundleEntity;
use SymfonyComponentValidatorConstraints as Assert;
//...
class Branch{
/**
* @AssertNotBlank
*/
protected $name;
}
Can you try this?
Also, you can test the validation like this from your controller:
// ...
use MyMainBundleEntityBranch;
public function indexAction()
{
$branch = new Branch();
$branch->setName('');
$validator = $this->get('validator');
$errors = $validator->validate($branch);
if (count($errors) > 0) {
return new Response(print_r($errors, true));
} else {
return new Response('Entity is valid');
}
}
使用NotBlank验证约束
You should check if the validation service has correctly aggragated your mapping:
$validator = $this->container->get('validator'); // do it your way
$metadata = $validator->getMetadataFactory()->getClassMetaData('MyMainBundleEntityBranch');
var_dump($metadata);
This will permit you to check if your yml configuration has been taken into account.
If not, check at the conventions used to name and place your validation yml file, even if it seems ok.
