Question

当我点击网页上的按钮时，我编写了一个芹菜任务，在我的数据库中设置了一些值。一切都好。现在我想编写一个更复杂的任务（disambiguation_task），它将一个字符串返回给我的Django视图（1.6.5）。代码是：

task_id = disambiguation_task.apply_async([json.dumps(json_request)])
async_result = AsyncResult(id=task_id,app=disambiguation_task)

一旦我尝试获取结果（async_result.get（）），它就会生成错误：

AsyncResult' object has no attribute 'replace'

带有以下追溯：

File "/home/patrick/django/entite-tracker-master/entitetracker/docentites/views.py" in get
  466.             result = async_result.get()
File "/usr/local/lib/python2.7/dist-packages/celery/result.py" in get
  169.             no_ack=no_ack,
File "/usr/local/lib/python2.7/dist-packages/celery/backends/amqp.py" in wait_for
  155.                                     on_interval=on_interval)
File "/usr/local/lib/python2.7/dist-packages/celery/backends/amqp.py" in consume
  225.             binding = self._create_binding(task_id)
File "/usr/local/lib/python2.7/dist-packages/celery/backends/amqp.py" in _create_binding
  99.         name = self.rkey(task_id)
File "/usr/local/lib/python2.7/dist-packages/celery/backends/amqp.py" in rkey
  111.         return task_id.replace('-', '')

Exception Type: AttributeError at /docentites/nodoc_desamb/news20150305NY501131/
Exception Value: 'AsyncResult' object has no attribute 'replace'

如果我尝试打印async_result.state，则会出现同样的错误。有人可以帮我解决这个错误吗？问候，帕特里克

disambiguation_task.apply_async([json.dumps(json_request)])返回AsyncResult对象，而不是任务ID。简单地说：

task_result = disambiguation_task.apply_async([json.dumps(json_request)])

# if you need to use the task_id somewhere else
async_result = AsyncResult(id=task_result.id, app=disambiguation_task)

芹菜与Django - AttributeError：'AsyncResult'对象没有属性'replace'
