Combined Forms and Defaults

Hello.

Now I would like to make life easier for all those people who write their projects based on the Symfony 2 framework .

In Symfony 2, there are great tools for creating forms from entities, as well as, more interestingly, merged forms .

So, if you need to set the default values ​​from entities (objects) in such a (unified) form, then you (like me) will wander around the Internet, looking for a solution to this problem, because it seems to be not in the documentation (in any case, I did not find it).

And so ... I generated the form on the fly (in the controller) as follows:

$client = $this->getDoctrine()->getRepository('CarrierUserBundle:Client')
                              ->findOneBy(array('id' => (int) $id));
$form = $this->createFormBuilder()->add('user', new UserType())
                                  ->add('client', new ClientType())
                                  ->getForm();

In this case, I could not set the default values ​​from the User and Client objects (it is also worth noting that “User one to many Clients” is connected between these objects). After a long search, I came across only half the solution to the problem, and I managed the rest myself. So, the solution itself:

$client = $this->getDoctrine()->getRepository('CarrierUserBundle:Client')
                              ->findOneBy(array('id' => (int) $id));
$form = $this->createForm(new Form\ClientType(), $client)
             ->add($this->createForm(new Form\UserType()));

We see that instead of createFormBuilder , I use directly createForm , into which the type of the form and the object are transferred (from the object, in fact, the default values ​​are taken). After that, another one is attached to the same form using the add method , but $ user is no longer transferred to it, because from $ client have a method getUser () , for this I mentioned the relationship between entities.

I hope I saved someone time. Use Symfony 2 and talk about your decisions, then it will be easier for all of us to do our job =)
