django: TypeError: 'tuple' object is not callable

提问by RuSs

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.

遇到类型错误,“元组”对象不可调用。知道它可能是什么吗?(不要担心缩进。它以奇怪的方式复制。)我正在尝试根据存储液的 PackSize 创建选择。

Views.py:

视图.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
if c == "1750 ML":
    pack_size = (
        ('1', '1')
        ('3', '3')
        (b, b)
        (h, h)
        (d, d)
        (e, e)
        (r, r)
    )
elif c == "1000 ML":
    pack_size = (
        ('1', '1')
        ('3', '3')
        ('6', '6')
        (b, b)
        (h, h)
        (d, d)
        (e, e)
        (r, r)
    )
elif c == "750 ML":
    pack_size = (
        ('1', '1')
        ('3', '3')
        ('6', '6')
        (b, b)
        (h, h)
        (c, d)
        (e, e)
        (r, r)
    )     
elif c == "375 ML":
    pack_size = (
        ('3', '3')
        ('6', '6')
        ('12', '12')
        (b, b)
        (h, h)
        (d, d)
        (e, e)
        (r, r)
    )        
elif c == "200 ML":
    pack_size = (
        ('12', '24')
        ('24', '24')
        (b, b)
        (c, c)
        (c, d)
        (e, e)
        (r, r)
    ) 
else:
    pack_size = (
        (b, b)
        (c, c)
        (c, d)
        (e, e)
        (r, r)
    )        




if request.method == "POST":
    f = AddToOrderForm(request.POST)

    if f.is_valid():
        z = f.save(commit=False)
        z.TotalPrice = (float(y)) * (float(g))
        z.storeliquorID = a
        z.orderID = x

        z.save()        

    return HttpResponseRedirect('/stores/get/%s' % store_id)

else:
    f = AddToOrderForm()
    f.fields['OrderAmount'].choices = pack_size      
args = {}


args['liquor'] = a
args['s'] = s
args['form'] = f   

return render(request,'storeliquor.html', args)

You're missing comma (,) inbetween:

您之间缺少逗号 ( ,):

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

Put comma:

输入逗号:

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

回答by Arun Rathi

There is comma missing in your tuple.

您的元组中缺少逗号。

insert the comma between the tuples as shown:

在元组之间插入逗号,如下所示:

pack_size = (('1', '1'),('3', '3'),(b, b),(h, h),(d, d), (e, e),(r, r))

pack_size = (('1', '1'),('3', '3'),(b, b),(h, h),(d, d), (e, e),(r, r))

Do the same for all
