I have a form type that has this field:
->add('action', 'text', array(
'required' => false,
))
The form type maps to an entity that has a property action.
The problem is when I render this form in twig, the field is pre-populated with the form's HTTP action URL, which is clearly not what I want.
Do I have to rename the form field and entity property to avoid this collision?
I was incorrectly initializing the form in my controller. I was doing this:
$filterForm = $this->createForm(new ActionLogFilterType(), array(
'action' => $this->generateUrl('admin.action_logs.index'),
'method' => 'GET',
));
When I needed to do this:
$filterForm = $this->createForm(new ActionLogFilterType(), null, array(
'action' => $this->generateUrl('admin.action_logs.index'),
'method' => 'GET',
));
So it turns out I can indeed use action as a form field as I hoped.
In Symfony 2.3 are the variables method and action added, see http://symfony.com/doc/current/reference/forms/twig_reference.html. So, yes, you will have to rename it.

In my form, I have a field of type EntityClass:
$builder
->add(
'user',
EntityType::class,
[
'required' => false,
'label' => 'User',
'placeholder' => 'Please choose',
'choice_label' => 'email',
'choice_value' => 'id',
'class' => 'AppBundle:User',
]
)
;
This field works fine - until I try to pre-fill it from my PHP code. Then it stays empty, and only shows "Please choose".
Pre-filling looks like this:
$user = $this->userRepository->find(...);
$form->get('user')->setData($user);
But it also does not work if I call ->setData($user->getId()), or even ->setData($user->getEmail()).
So how do I prefill a field of type EntityType?
You should not prefill Form, you should prefill Model, if you need it.
$user = $this->userRepository->find(...);
$entity = new YourEntity();
$entity->setUser($user);
$form = $this->createForm(YourEntity::class, $entity);
And it's not about EntityType. It's about any Type in Symfony - there is no way to bind a default value for them. Data is binded on Model.
UPD from comment: It's not true, that Form could be used without Model. It could be used without Doctrine Entity or any other ORM (or not ORM) Entity. But they still operate with data, i.o. with model.
\Symfony\Component\Form\FormFactoryInterface has definition
public function create($type = 'form', $data = null, array $options = array());
So some kind of $data is always present when you're using Form Component.
I actually did some tricks so i could be able to persist a user if its ID is passed by an url parameter. (Custom action from user list).
/admin/se/api/bundle/create?user=7
I actually could not find how to send the user entity returned by a findByOne(array('id' => $user_id)) so i guess i'll need to pass the $user_id through a hidden field and handle its value in a PrePersist
Otherwise passing the id that way
->add('user', 'hidden', array('data' => $user_id))
will return an error :
This value is not valid.
Symfony\Component\Validator\ConstraintViolation
Object(Symfony\Component\Form\Form).children[user] = 7
Caused by:
Symfony\Component\Form\Exception\TransformationFailedException
Compound forms expect an array or NULL on submission.
This is my first attempt that is not working :
$container = $this->getConfigurationPool()->getContainer();
$request = $container->get('request');
$user_id = $request->get('user');
if(!empty($user_id)){
$em = $this->getModelManager()->getEntityManager($this->getClass());
$user = $em->getRepository('ApiBundle:User')->findOneBy(array('id' => $user_id));
if($user){
$formMapper
->with('User', array('description' => '<strong>User : </strong>'.$user->getDisplayName()))
->add('user', 'hidden', array('data' => $user_id))
// this of course doesn't work as explained above. How can i have my own hidden input not related to any property
->end();
}
So how would i do that? Any better solution is welcomed.
Well this is the best trick i found. I wish 'sonata_type_model_hidden' has more options. I guess i could do my own custom field to be able to do that. But i'm not sure how and anyway this solution is fast to implement.
$formMapper
->with('Guide', array('description' => '<strong>Guide : </strong>'.$guide->getDisplayName()))
->add('guide', 'sonata_type_model_autocomplete', array(
'property' => array('firstname', 'lastname', 'username', 'email'),
'data_class' => null, // IMPORTANT
'data' => $guide,
'attr' => array('class' => 'sonata-autocomplete-hidden'), // custom class
'label_attr' => array('class' => 'sonata-autocomplete-hidden'), // custom class
)
)
->end();
To hide the field :
.sonata-autocomplete-hidden{
display:none;
}
If you have any better solutions, you're welcome.
i have an array with entities. I know that symfony has a collection type, but that what i want doesn't work as intended. I have created a FormType for a single entity and a FormType for the collection (formtype code for the collection):
$builder
->add('list', 'collection', array(
'label' => 'list',
'type' => new SingleItemType(),
'allow_add' => true,
'allow_delete' => true,
'by_reference' => false
));
Now i have tried to create a Form
$arr = array(new Item(), new Item(), new Item());
$this->createForm(new CollectionListType(), $arr);
But this doesn't work; I get an error which means i should set "Item" as data_class, if i do this, an another error appears which means i should set data_class to null.
Another approach was to create a dummy entity which holds my array of Item-Entities but this doesn't works too.
Is there a simple approach to display a list of entities as collection form?
Greetings
I'm not sure totally understand your problem but I think you must create first an Entity with getList()/setList(). In your collection field, you can add a new "default" entity passing a value to "data" key in option array.
The user has the ability to filter a list of data. For this use case i build a form type "UserFilterType", which look like this.
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('firstName', 'text', array('attr' => array('maxlength' => 255)))
->add('roles', 'entity', array(
'class' => 'ApplicationUserBundle:Role',
'property' => 'name',
'label' => false,
'multiple' => false,
'expanded' => false,
'empty_value' => 'msg.role.all',
'translation_domain' => 'role', 'required' => false)
));
}
So far everything works very well. The user can filter the output. But if the user wants to sort the output, eg by first name. A get request executed and filter options lost. I will save the filter options temporary, maybe in a session.
I try the following option:
$session = $this->getRequest()->getSession();
$session->set('userFilter', serialize($form->getData());
.....
$form->setData(unserialize($session->set('userFilter')));
The form fields are filled out correctly, but if i execute the filter again with a post request i get the following error message
"Entities passed to the choice field must be managed. Maybe persist them in the entity manager?"
Does anyone have any idea how I should proceed? I hope I could describe my problem understandable.
Instead of field type 'entity', you might want to use 'choice' and set the querybuilder for the choicelist in the form.
This is caused by the fact, that 'entity' type field expects an Entity as a value. When you unserialize the data, even if it was an Entity from the database, the EntityManager doesn't know this(the unserialized object is just an instance of ApplicationUserBundle:Role, it might not be in the database yet) so this is not a "managed" entity.
You can also add the EntityManager that you found a "lost lamb" and add it back to the manager by:
$filters = unserialize($session->set('userFilter'));
$roles = $filters['roles'];
$entityManager->merge($roles);
This way you tell the EntityManager that this object is already persisted(through ->persist) and EntityManager should treat it as an object fetched from the database
but you need to test it
I mean to have custom date handler in views ,according to documentation of views i should implement hook_views_api and hook_views_data .
my pseudo
function mymodule_views_api() {
return array(
'api' => views_api_version(),
);
}
and in hook_views_data()
function mymodule_views_data() {
$data = array();
$data['node']['created'] = array(
'group' => t('Mul2'),
'title' => t('Post date'), // The item it appears as on the UI,
'help' => t('The date the content was posted.'), // The help that appears on the UI,
'field' => array(
'handler' => 'views_handler_field_date',
'click sortable' => TRUE,
),
'sort' => array(
'handler' => 'views_handler_sort_date',
),
'filter' => array(
'handler' => 'views_handler_filter_date',
),
);
return $data;
}
It's ok and create a views field gorup (Mul2),
I set it hanlder date handler for test, but it not work correctly and just show Mul2: Array , and broken/missing handler in configuration of it.
I try successfully get data of custom table with views data .Is it correct to set handler for a field before handlered (like created in node ) ?
any solution?any idea?
Method of Impelementation is correct, my mistake was in use a field that before set handler for it $data['node']['created'] .
if you want to change default handler of handled field you have use hook_views_data_alter(&$data) instead of try to set handler for it again!!!(Mul2:array because of you try to set handler for handled field).
