product_reviews queryset.

from __future__ import division has nothing this; you're trying divide value method itself, instead of calling method first proper operand. compare , contrast:

>>> class x(object): ...   def count(self): ...     return 1 ...  >>> x = x() >>> 1 / x.count traceback (most recent call last):   file "<stdin>", line 1, in <module> typeerror: unsupported operand type(s) /: 'int' , 'instancemethod' >>> 1 / x.count() 1
