Argument 1 passed to Illuminate\Auth\Guard::login() must be an instance of Illuminate\Contracts\Auth\Authenticatable error in laravel 5

Question

I’m building a carpool app where its the intention that when a user registers they’re able to fill in they have a car however this car is in a table on its own.

When I try to create it with the field checkt I get this error:

Argument 1 passed to Illuminate\Auth\Guard::login() must be an instance of Illuminate\Contracts\Auth\Authenticatable, instance of App\Cars given, called in /home/vagrant/Code/carpool-app-going-your-way/www/vendor/compiled.php on line 2078 and defined

Any ideas on how to fix it?

Here is my code:

registrar.php

public function create(array $data)
{
    if (isset($_POST["ihaveacar"])){

        return Cars::create([
            'seats'=>$data['seats'],
            'seats_taken'=>'0',


        ]);



    }

    return User::create([
        'first_name' => $data['first_name'],
        'last_name' => $data['last_name'],
        'screen_name' => $data['screen_name'],
        'email' => $data['email'],
        'password' => bcrypt($data['password']),
        'route' => $data['route'],
        'state' => $data['state'],
        'description' => $data['description'],
        'license_since' => $data['license_since'],
    ]);

}

User.php

<?php namespace App;

use Illuminate\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;
use Illuminate\Database\Eloquent\SoftDeletes;



class User extends model implements AuthenticatableContract, CanResetPasswordContract{

    use Authenticatable, CanResetPassword;


    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'users';

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = ['first_name', 'last_name', 'screen_name', 'email', 'password', 'birthday', 'license_since', 'kilometers', 'state', 'route','image','description','soft_delete', 'is_admin'];

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = ['password', 'remember_token'];



    use SoftDeletes;
    protected $dates = ['deletec_at', 'created_at', 'updated_at'];



}

Any ideas how to fix this?

Thanks in advance

Edit: all of a sudden it seems to be running without errors. I don’t get it.

Answer 1

You're passing an instance of App\Cars to the registrar via the create() method. Remove all non-login logic from the registrar and only perform said logic after the authentication logic is actually complete.

Answer 2

You’re returning two different object types in your create() method. If the request has a parameter called ihaveacar then you return a Car instance, otherwise you return a User instance. You need to make your mind up what your create() method should actually return.

Answer 3

you should extend Illuminate\Foundation\Auth\User like

use Illuminate\Foundation\Auth\User as AuthUser;
class Member extends AuthUser
{
    public  $table='members';
    protected $fillable = ['name', 'password','qq','phone'];

}
