Symfony2 subform for non-entities

I'm trying to create a form like this to manage permissions.

twitter   sms   email    readonwebsite
user0    yes      no     yes          yes
user1     no     yes      no          yes
user2     no      no      no          yes
user3    yes     yes     yes          yes

The current way I'm doing this is using a foreach loop for each subuser and adding this directly to the form

$form = $form->add($subUser->getId() . '_twitter', 'checkbox', array
(
    'label'     => 'twitter',
    'required'  => false,
    'mapped' => false,
    'data' => (bool)//original checkbox value derived from db value
));

and repeated code for sms, email, and read permissions. This doesn't seem very elegant. In the form processing, I would have to deal with keys like 1337_twitter and 69_sms. Is there a way that I can process the form like $form[$subUser->getId()]['twitter']?

I'm assuming you're using Doctrine because you haven't specified which ORM you're using. Do you have a Permission object? If you create a relationship between permissions and users that would be a lot cleaner. You could add permissions to your user form and it would be easy to manage.

So your permissions table would contain a record for 'twitter', 'sms', 'email', 'readonwebsite'.

You could set up your entities and form like below:

e.g.

// src/PathTo/YourBundle/Entity/Permission.php
class Permission
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=255, nullable=false)
     */
    private $name;  // e.g. 'twitter' or 'email'

    /**
     * @ORM\ManyToMany(targetEntity="User", mappedBy="permissions")
     */
    private $users;
}


// src/PathTo/YourBundle/Entity/User.php
class User
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @ORM\ManyToMany(targetEntity="Permssion")
     * @ORM\JoinTable(name="user_permission",
     *     joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")},
     *     inverseJoinColumns={@ORM\JoinColumn(name="permission_id", referencedColumnName="id")}
     * )
     */
    private $permissions;
}


// src/PathTo/YourBundle/Form/Type/UserFormType.php

class UserFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            // Add more fields
            ->add('permissions', null, array(
                'expanded' => true, // Creates checkboxes
            ))
        ;
    }

    // ...
}

Then in your controller

// src/PathTo/YourBundle/Controller/UserContoller.php
public function editAction($id, Request $request)
{
    // ...
    // Get your user object

    $form = $this->createForm(new UserFormType(), $user);

    $form->handleRequest($request);

    if ($form->isValid()) 
        $em->persist($user);
        $em->flush();

        // redirect back to some edit page
        // ...
    }

    // render some form template
    // ...
}

It's that simple :)
