如何使用Laravel 5授权执行注销功能

我的登出功能有问题。这是我的路线列表:

Route::get('/', ['as' => 'home', function () {
    return "Home Page";
}]);
Route::get('profile', function() {
    return "Welcome back. " . Auth::user()->email;
})->before('auth');
Route::get('login','SessionsController@create'); //alias
Route::get('logout', 'SessionsController@destroy'); //alias
Route::resource('sessions','SessionsController');

在我的控制器中，我在logout中有这个函数:

public function destroy()
{
    Auth::logout();
    return Redirect::home();
}

然后当我成功登录后访问这个URL时，我得到了这个错误:

QueryException in Connection.php line 636: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'remember_token' in 'field list' (SQL: update `users` set `updated_at` = 2015-09-02 07:16:31, `remember_token` = GXCcx6tpanPh651DSMkRk3PRWLzyKc3TgYuhz8oPySn2OoESJBrfhbeFpd6C where `id` = 1)

我不知道我的错误在哪里。
