Class 'Illuminate\Foundation\Auth\User' not found JWT Auth Laravel - php

Question

I have written code for registration and login using JWT authentication. In this code registration function works fine but login function doesn't works. Login function prompts an error as Class 'Illuminate\Foundation\Auth\User' not found
My user model is
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
protected $table = 'users';
public $timestamps = false;
protected $primaryKey = 'user_name';
protected $fillable = ['user_name','password'];
}
My UserController is
class UsersController extends Controller
{
public function login()
{
$credentials = request()->only('user_name','password');
try{
$token = JWTAuth::attempt($credentials);
if($token){
return response()->json(['error'=>'invalid_credentials'],401);
}
}
catch(JWTException $e){
return response()->json(['error'=>'something went wrong'],500);
}
return response()->json(['token'=>$token],200);
}
public function register()
{
$user_name = request()->user_name;
$password = request()->password;
$user = User::create([
'user_name'=>$user_name,
'password'=>bcrypt($password)
]);
$token = JWTAuth::fromUser($user);
return response()->json(['token'=>$token],200);
}
}
The login function shows the error as
Class 'Illuminate\Foundation\Auth\User' not found

Answer 1

In your controller I guess you forgot to use your model "User" add it below the namespace declaration, Or it's a conflict with Illuminate\Foundation\Auth\User
use\App\User;
And you must run the following:
composer update
composer dump-autoload

Answer 2

The problem exists with my user model and I solved it
<?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;
class User extends Model implements AuthenticatableContract, CanResetPasswordContract
{use Authenticatable, CanResetPassword;
//
protected $table = 'users';
public $timestamps = false;
protected $primaryKey = 'user_name';
protected $fillable = ['user_name','c_name','accessibility_level','password','role','contact_number','address'];
}
