Question

我已经启动并运行了'make：auth（）'并且我在迁移中做了很少的修改，即添加了一个名为'admin'的布尔字段，默认情况下我将该字段设为0。现在我在视图'Make Admin'中创建了一个按钮，我希望此按钮将管理字段从零更新为1.

我厌倦了以下但是没有更新数据库列值。

控制器：

public function makeAdmin($id)
    {
        $user = User::find($id);
            if($user){
                $user->admin = '1';
                $user->save();
                return Redirect::to('/users');
            }
}

Answer 1

您添加了布尔字段并尝试使用字符串值更新（＆＃39; 1＆＃39;）..这也可能是一个问题。

Answer 2

确保将新列添加到$fillable模型中的User字段，因为所有Eloquent模型都可以保护您免受批量分配。

应用/ user.php的

/** * The attributes that are mass assignable. * * @var array */ protected $fillable = [ 'name', 'admin', 'email', 'password', ];
