Prof和Dev版本中的Symfony2表单方法不同

Question

I have problem with my project. My problem exist when I try to delete some data from entity. My controller was generated with Sesio generator. Here is my code:

/**
 * Deletes
 * @Route("/{id}/delete", name="delete")
 * @Method({"DELETE"})
 */
public function deleteAction(Request $request, Task $task) {

    $form = $this->createDeleteForm($task);
    $form->handleRequest($request);


    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $em->remove($task);
        $em->flush();
        $this->get('session')->getFlashBag()->add('notice_success', 'Success');
    } else {
        $this->get('session')->getFlashBag()->add('notice_error', 'NO DELETE');
    }
    return $this->redirectToRoute('task');
}

/**
 * Creates a form to delete.
 */
private function createDeleteForm(Task $task) {
    return $this->createFormBuilder()
                    ->setAction($this->generateUrl('delete', array('id' => $task->getId())))

                    ->add('submit', \Symfony\Component\Form\Extension\Core\Type\SubmitType::class, array('label' => 'Delete'))
                    ->getForm()
    ;
}

I have to tell you that this code work nice on DEV (app_dev.php) but It isn't working in PROD version.

I try to solve that problem and I have tried to change form method to POST and it work property od PROD and DEV. It look like DELETE method doesnt work in PROD version.

Someone have similar problem?

If you're using the AppCache, the kernel will ignore the _method parameter added for DELETE method.

To solve the problem in your web/app.php call Request::enableHttpMethodParameterOverride(); before creating the Request object:

...
$kernel = new AppCache($kernel);
Request::enableHttpMethodParameterOverride();// <-- add this line
$request = Request::createFromGlobals();
...
