芹菜，集團的任務，AttributeError的：「NoneType」對象有沒有屬性「應用」

我試圖運行一組的芹菜任務如下：芹菜，集團的任務，AttributeError的：「NoneType」對象有沒有屬性「應用」

@shared_task 
def run_sms_task(smstask_id): 

    smstask = SmsTask.objects.get(id = smstask_id) 
    if smstask: 

     phones = [] 
     for user in smstask.userlist.users.all(): 
      phones.append(user.profile.phone) 

     g = group(send_sms_async(phone, smstask.text) for phone in phones) 
     g.apply_async() 

     smstask.status = 3 
     smstask.save()

任務已部分執行，並最終引發以下錯誤：

[2016-11-01 13:42:03,362: ERROR/MainProcess] Task sms_center.tasks.run_sms_task[d575fb59-6b0a-4ea6-851f-0902ef6bd7b9] raised unexpected: AttributeError("'NoneType' object has no attribute 'app'",)

如果您有任何想法，歡迎您提供幫助。謝謝！

請顯示完整的回溯。 –

@DanielRoseman我已將它添加到問題中。 –

我發現了這個錯誤。我沒有注意到該組是由子任務創建的而不是任務。然後創建正確的羣組：

g = group(send_sms_async.s(phone, smstask.text) for phone in phones)

希望這個答案可以節省一些分鐘，如果你遇到了同樣的問題！
