Using 'contain()' in the AuthComponent array to specify fields

Question

In CakePHP\'s documentation I\'ve seen from version 2.2 has been added the configuration key \'contain\' for the AuthComponent:

The core authentication ob

Answer 1

you were almost there. Just add the "fields" key on your first example, like this :

'Auth' => array(
    'authenticate'      => array(
        'Form' => array(
            'contain'   => array('User' => array('fields'=>array('id', 'full_name'))),
            'fields'    => array('username' => 'email'),
        )
    )
)

NB : while this is syntaxically correct, I do not see why 'User' should contain 'User'... well YMMV

Answer 2

Contain() is used to contain a DIFFERENT model, not the same one Auth is already retrieving (unless you're trying to contain other User's ie their friends or something - but then you'd likely have an alias, and not 'User').

So, an example would be:

'Auth' => array(
    'authenticate'      => array(
        'Form' => array(
            'contain'   => array('Post'),
            'fields'    => array('username' => 'email'),
        )
    )
)

Which would then cause Auth to retreive the user's Posts as well when it retrieves the user's data.
