It means that your Grid repository method doesn't return QueryBuilder, maybe at now you return array/one entity objects with getResult() method inside Repository method.

Symfony how to bind request data to form without HTML

When you want to bind data to form (for example in your REST application) as in FOSRestBundle, but after handleRequest() you doesn't have submitted data, try to map it with

$this->get('form.factory')->createNamed('', MyFormType::class, $dummy, ['csrf_protection' => false]);

, where first parameter is empty string, the second is form, $dummy is for model or entity object. So you can use form validation in simple Symfony action.

FOSRestBundle invalid form doesn't use ExceptionWrapper

If your FOSRestBundle response doesn't have normal type, (for example, as below):

{
    "form": {
        "children": {
            "currency": {},
            "limit": {
                "errors": [
                    "This value should be greater than or equal to 0."                ]
            },
            "": {},
            "name": {}
        }
    },
    "errors": []
},

As we see, there are no 'code' and 'message' keys, so FOSRestBundle type is wrong. To fix it, use

$view->getContext()->setAttribute('status_code', Response::HTTP_BAD_REQUEST);

for your $view object.

Symfony FileType doesnt append file
