the adutomatic crud operation generated by symfony and also the symfony demo application has the following code structure for the delete action
/**
* Deletes a testing entity.
*
* @Route("/{id}", name="testing_delete")
* @Method("DELETE")
*/
public function deleteAction(Request $request, testing $testing)
{
$form = $this->createDeleteForm($testing);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->remove($testing);
$em->flush();
}
return $this->redirectToRoute('testing_index');
}
/**
* Creates a form to delete a testing entity.
*
* @param testing $testing The testing entity
*
* @return \Symfony\Component\Form\Form The form
*/
private function createDeleteForm(testing $testing)
{
return $this->createFormBuilder()
->setAction($this->generateUrl('testing_delete', array('id' => $testing->getId())))
->setMethod('DELETE')
->getForm()
;
}
my question is why do we need a form to delete? cant we just have a link in the twig with an id parameter set accordingly, cant we just do the following, why do we need to check if the entity isValid() inside a form before deleteing it?
/**
* test delete
* @Route("/{id}", name="testing_delete")
* @Method("DELETE")
*/
public function deleteAction(testing $testing) {
$em = $this->getDoctrine()->getManager();
$em->remove($testing);
$em->flush();
return $this->redirectToRoute('testing_showall');
}
