用户组控制器

class UserGroupsController extends Controller\n{\n    public function edit(UserGroup $userGroup)\n      {        \n        if (Auth::check())\n        {\n          $users = User::pluck(\'name\',\'id\')->all();\n          $groups = Group::pluck(\'name\',\'id\')->all();\n          return view(\'users-group.edit\', compact(\'userGroup\',\'users\',\'groups\'));\n        }else{\n          return redirect(\'login\');\n        }\n\n    }\n}\n
