Django 单元测试celery时的坑

1. 在单元测试里面创建了一个对象

deduct = DeductQueue.objects.create(user=User.objects.get(id=2), amount=2,
                                                xz_user_id=666,
                                                deduct_date=datetime.datetime.now(),
                                                log={}, deduct_type=DeductType.HEAT, coin_type=CoinType.HEAT,
                                                exchange_desc=TransferDesc.DAILY,
                                                exchange_type=ExchangeType.DAILY, )
r1 = re_deduct_heat.apply_async(args=(1,))
print(r1.get())

2. 执行的任务里面查找该对象

@app.task
def re_deduct_heat(pk):
    
    deduct = get_object_or_None(DeductQueue, pk=pk)
    return decuct.id

3. 发现找不到该对象

单元测试执行是打印的结果(r1.get())：NoneType has no 'id'

原因&
