PermanenttaskFailure:“module”对象在加载所有模块时没有属性错误

flask google-app-engine

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()

这很好,但有时我会出错:

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

为什么有时候有用,有时候不行? 我的代码与 admin_required ,所以我不知道发生了什么。

从google文档

You can't pass a method defined in the request handler module.
上面最后一点值得特别注意:通过一个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-将不起作用。你可以打电话 deferred.defer来自请求处理程序模块,但是必须在别处定义它!

SO传递方法 autofavoritetweettask 到 autofavoritetweet 不起作用? 但为什么大部分时间都是这样:

这个错误是在加载模块时出现的。我不明白为什么有时所有模块都加载到任务队列中,但有时不是。

谢谢您。更新1:管理员要求是

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
