the Error NoneType object has no attribute is_bound is because you are calling is_valid method on the form class detail but not the detail instance object form object.

change your code to:

form1 = detail(request.POST) # Better to user uppercase class name(Detail)
form2 = detail2(request.POST)
if form1.is_valid() or form2.is_valid():
    ...
