                  问题描述

                  出现类型错误,元组"对象不可调用.知道它可能是什么吗?(不要担心缩进.它会奇怪地复制.)我正在尝试根据 storeliquor 的 PackSize 创建选择.

                  Getting a type error, 'tuple' object is not callable. Any idea what it could be? (dont worry about the indentation. It copies in weird.) I'm trying to create choices based on PackSize of storeliquor.

                  Views.py:

                  def storeliquor(request, store_id, liquor_id):        
                  a = StoreLiquor.objects.get(StoreLiquorID=liquor_id)
                  s = Store.objects.get(StoreID=store_id)
                  x = Order.objects.get(storeID=s, Active=True)
                  y = a.OffPremisePrice
                  c = a.BottleSize
                  
                  g = request.POST.get('OrderAmount', '')
                  b = a.PackSize
                  h = b*2
                  d = b*3
                  e = b*4
                  r = b*5

                  推荐答案

                  中间缺少逗号(,):

                  >>> ((1,2) (2,3))
                  Traceback (most recent call last):
                    File "<stdin>", line 1, in <module>
                  TypeError: 'tuple' object is not callable
                  

                  加逗号:

                  >>> ((1,2), (2,3))
                  ((1, 2), (2, 3))
