Question

有没有办法使用定义自定义名称的属性创建EndpointsModel的子类？即：

    class ProfilesApi(remote.Service):
    @Profile.method(name='user', path='user')
      def details(self, profile):
        return profile

    class Profile(EndpointsModel):
      user_id = ndb.StringProperty('uid')

收到以下错误：

问题似乎在endpoints_proto_datastore中，对吧？我想有一种特定的方法可以做到这一点。我还没有找到任何关于它的样本或文档。
