在laravel-permission mongodb和jenssegers中存储权限和角色

Question

i使用jenssegers-mongodb和laravel-permission-mongodb。当我尝试存储分配给角色（image is here）的权限时，存储了该权限，但具有此权限（而不是更新和权限）的角色没有分配给角色

我存储权限的代码：

public function store(Request $request)
{
    $this->validate($request, [
        'name'=>'required|max:40',
    ]);
    $permission = new Permission();
    $permission->name = $request->name;
    $permission->save();

    if ($request->roles <> '') { 
        foreach ($request->roles as $key=>$value) {
            $role = Role::find($value);
            $role->permissions()->attach($permission);
        }
    }
    return redirect()->route('permissions.index')->with('success','Permission added successfully');

}
