PermanentTaskFailure：加载所有模块时，“模块”对象没有属性错误

Question

我有请求处理程序：

@app.route('/autofavoritetweet/')
def autofavoritetweet():
  deferred.defer(autofavoritetweettask,twaccount_db.key,_countdown=random.randint(0,60),_retry_options=options)    

传递给任务队列的方法是

def autofavoritetweettask(twaccount_db_key):
   api.create_favorite()

这工作正常，但有时会出现此错误：

PermanentTaskFailure: 'module' object has no attribute 'admin_required'

为什么有时会起作用，有时却不起作用？ 我的代码没有与admin_required相关的任何内容，所以我不知道发生了什么。

来自Google文档

You can't pass a method defined in the request handler module.

     

上面的最后一点值得特别注意：传递方法   在请求处理程序模块中定义-指定为   app.yaml中的请求处理程序-不起作用。你可以打电话   deferred.defer来自请求处理程序模块，但是功能   传递给它必须在其他地方定义！

因此无法将方法autofavoritetweettask传递到autofavoritetweet吗？ 但是为什么它在大多数时间都有效：

仅在加载模块时出现错误。 我不明白为什么有时所有模块都加载到任务队列中，但有时却不加载。

谢谢。 更新1：Admin_require是

def admin_required(f):
  decorator_order_guard(f, 'auth.admin_required')

  @functools.wraps(f)
  def decorated_function(*args, **kwargs):
    if is_logged_in() and current_user_db().admin:
      return f(*args, **kwargs)
    if not is_logged_in() and flask.request.path.startswith('/api/'):
      return flask.abort(401)
    if not is_logged_in():
      return flask.redirect(flask.url_for('signin', next=flask.request.url))
    return flask.abort(403)

  return decorated_function
