Is it possible to filter the choicelist after querying the entities?
I know that you can filter it with the query_builder option but in some case you can't filter in this way.
For example if you use "array" as column definition in your entity.
I find only bad way to resolve this problem:
$builder->add(
'contact',
'entity',
array(
'query_builder' => function (EntityRepository $repository) {
return $repository->createQueryBuilder('c')
->where('c.roles LIKE :role')->setParameter('role', '%ROLE_CONTACT%');
},
'label' => 'Contact',
'class' => 'AppBundle\Entity\User',
'required' => false
)
)Or you must implement your own loader.
I think it would be nice and easy to use if you have an option to filter the data after hydration.
Like this:
$builder->add(
'contact',
'entity',
array(
'choice_filter' => function ($user) {
return $user->hasRole('ROLE_CONTACT');
},
'label' => 'Contact',
'class' => 'AppBundle\Entity\User',
'required' => false
)
)As with #14050 choice_filter can be a callback or property path. And i think it should be add in ChoiceType so you can filter every choicelist.
I know you should use query_builder to filter the data in the database but in some case you don't have a choice.
