Facebook Login with Sentry, A password is required for user [email], none given

Question

I\'m trying to allow users to login using facebook but my user management is based on sentry as you know if you connect from facebook, you wont need a password unless you ar

Answer 1

I think that when you create the user you need to use Sentry::createUser()

$user = Sentry::createUser(array(
    'name'     => $me['first_name'].' '.$me['last_name'],
    'email'    => $me['email'],
    'password' => 'test',
    'photo'    => 'https://graph.facebook.com/'.$me['username'].'/picture?type=large',
));

And then use Sentry::login($user, false); to force a login for the user without a password.

You probably also want to put something in the password field other than test if you also have a regular non-facebook login.

Also you may have to activate the user depending on what your plans were with that email:

//You could email this to the user from here.
$activationCode = $user->getActivationCode();

//OR just activate immediately. 
$user->attemptActivation($activationCode);

Answer 2

I'm looking at doing something similar, and was thinking of using the facebook uid as the password. Would this not work?

Edit: I can confirm the following works for me:

function callback()
{
    $code = Input::get('code');
    if (strlen($code) == 0) return Redirect::to('/')->with('message', 'There was an error communicating with Facebook');

    $facebook = new Facebook(Config::get('facebook'));
    $uid = $facebook->getUser();

    if ($uid == 0) return Redirect::to('/')->with('message', 'There was an error');

    $me = $facebook->api('/me');
    //dd($me);

    //Check if user profile exists
    $profile = Profile::whereUid($uid)->first();
    if (empty($profile)) {

        // Create the user
        $user = Sentry::createUser(array(
            'email'      => $me['email'],
            'password'   => $uid,
            'first_name' => $me['first_name'],
            'last_name'  => $me['last_name'],
            'photo'      =>  'https://graph.facebook.com/'.$me['username'].'/picture?type=large',
            'activated'  => 1
        ));

        // Find the group using the group id
        $registered = Sentry::findGroupById(2);
        // Assign the group to the user
        $user->addGroup($registered);

        $profile = new Profile();
        $profile->uid = $uid;
        $profile->username = $me['username'];
        $profile = $user->profiles()->save($profile);
    }

    $profile->access_token = $facebook->getAccessToken();
    $profile->save();

    $user = $profile->user;
    Sentry::login($user, false);
    $user = Sentry::getUser();

    echo $user->first_name . " logged in.";
    //return Redirect::to('/')->with('message', 'Logged in with Facebook');
}

Also note that you'll need customize the model sentry uses using this method (http://forums.laravel.io/viewtopic.php?pid=48274#p48274) in order to specify the relationship with profiles
