My bad. I wrote that example without thinking about it. Yes, it would
have to be in the controller because AuthComponent isn't available in
a view, of course.
What you could do is extract the following & follower IDs in the login
action and store them in the session. That's where Auth keeps the data
is returns with the user() method so there's a little bit of
duplication but not much. Especially as you'll only need to extract
the IDs once.
public function login()
{
// other stuff ...
$user = $this->Auth->user();
$this->Session->write(
'User.following',
Set::extract('/Following/id', $user)
);
$this->Session->write(
'User.follower',
Set::extract('/Follower/id', $user)
);
}
Then in you views you can do something like
if (in_array($some_user_id, $this->Session->read('User.following')))
{
...
}
