I'm Tring to assign default role to new user But I failed to assigned it. All user information stored in database but Role can't stored in table. Where i mistaked in this code. Help me.My English not good, Sorry for miss-communication.
This is My Code of User.php, Role.php, RegisterController.php and HomeController.php Files. See and tell me "where i doing wrong?"
This is User.php File
namespace App;
use App\Role;
use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
use Notifiable;
/**
* #param string|array $roles
*/
public function authorizeRoles($roles)
{
if (is_array($roles)) {
return $this->hasAnyRole($roles) ||
abort(401, 'This action is unauthorized.');
}
return $this->hasRole($roles) ||
abort(401, 'This action is unauthorized.');
}
/**
* Check multiple roles
* #param array $roles
*/
public function hasAnyRole($roles)
{
return null !== $this->roles()->whereIn('name', $roles)->first();
}
/**
* Check one role
* #param string $role
*/
public function hasRole($role)
{
return null !== $this->roles()->where('name', $role)->first();
}
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'name', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
/**
* The attributes that should be cast to native types.
*
* #var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
}
This is Role.php File
<?php
namespace App;
use App\User;
use Illuminate\Database\Eloquent\Model;
class Role extends Model
{
public function users()
{
return $this->belongsToMany(User::class);
}
}
This RegisterController.php File.
<?php
namespace App\Http\Controllers\Auth;
use App\Role;
use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;
class RegisterController extends Controller
{
/*

use RegistersUsers;
/**

protected $redirectTo = '/home';
/**

$this->middleware('guest');
}

protected function validator(array $data)
{
return Validator::make($data, [
'name' => ['required', 'string', 'max:255'],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
'password' => ['required', 'string', 'min:8', 'confirmed'],
]);
}
/**
* Create a new user instance after a valid registration.
*
* #param array $data
* #return \App\User
*/
protected function create(array $data)
{
$user = User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
]);
$user
->roles()
->attach(Role::where('name', 'student')->first());
return $user;
}
This is my role_user database Table
User Database Table
Role Database Table

Answer 1

Refactor your create method in RegisterController.php file like this:
protected function create(array $data)
{
$user = User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
]);
$user
->roles()
->attach(Role::where('name', 'student')->first());
return $user;
}
your rest of the code will not run after return.
and add roles relation to User model like this:
public function roles()
{
return $this->belongsToMany(User::class);
}

Answer 2

You can update your create function with this
protected function create(array $data)
{
return User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
]);
$role = new App\Role(['role' => 'student']);
$user->roles()->save($role);
return $user;
}

Answer 3

You don't currently have a roles() relation in your user model. Add the following
public function roles()
{
return $this->hasMany('App\Role');
}
