Django芹菜AbortableTask用法

Question

我想使用芹菜的AbortableTask功能，但文档示例似乎并没有为我工作。给出的例子是：

from celery.contrib.abortable import AbortableTask 

def MyLongRunningTask(AbortableTask): 

    def run(self, **kwargs): 
     logger = self.get_logger(**kwargs) 
     results = [] 
     for x in xrange(100): 
      # Check after every 5 loops.. 
      if x % 5 == 0: # alternatively, check when some timer is due 
       if self.is_aborted(**kwargs): 
        # Respect the aborted status and terminate 
        # gracefully 
        logger.warning("Task aborted.") 
        return None 
      y = do_something_expensive(x) 
      results.append(y) 
     logger.info("Task finished.") 
     return results 

和

from myproject.tasks import MyLongRunningTask 

def myview(request): 

    async_result = MyLongRunningTask.delay() 
    # async_result is of type AbortableAsyncResult 

    # After 10 seconds, abort the task 
    time.sleep(10) 
    async_result.abort() 

    ... 

不过，我得到的错误：

TypeError: MyLongRunningTask() takes exactly 1 argument (0 given) 

我在做什么错？

只是一个猜测，但我认为它应该是

class MyLongRunningTask(AbortableTask) 

，而不是

def MyLongRunningTask(AbortableTask)
