Can't authenticate user in laravel

Question

        $userdata = array(
            'email' => Input::get('email'),
            'password'  => Input::get('password')
            );



        if (Auth::attempt($userdata)) {

            echo 'SUCCESS!';

        } else {        

            return Redirect::to('login');

        }

when i run the application from browser i got this error :

Argument 1 passed to Illuminate\Auth\EloquentUserProvider::validateCredentials() must be an instance of Illuminate\Auth\UserInterface, instance of User given, called in /home/srtpl17/Sites/yatin.sr/vendor/laravel/framework/src/Illuminate/Auth/Guard.php on line 316 and defined

What have I done incorrectly?

Answer 1

It sounds like from your error that your User model does not implement UserInterface (the default User Model that comes with Laravel does this properly, so I'm guessing you made a custom one)

http://github.com/laravel/laravel/blob/master/app/models/User.php

Make sure that the User model looks like this:

use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableInterface;

class User extends Eloquent implements UserInterface, RemindableInterface {


/**
 * Get the unique identifier for the user.
 *
 * @return mixed
 */
public function getAuthIdentifier()
{
    return $this->getKey();
}

/**
 * Get the password for the user.
 *
 * @return string
 */
public function getAuthPassword()
{
    return $this->password;
}

/**
 * Get the e-mail address where password reminders are sent.
 *
 * @return string
 */
public function getReminderEmail()
{
    return $this->email;
}

// Add your other methods here

}

Answer 2

You don't show what userdata is defined as, but from the error message it seems like it's an instance of your User model class.

The Auth::attempt() method is looking for an array of the credentials not a model.
