Fluent interface on custom methods of custom Queryset class

Of course, if they're integers you could implement the "mul" as a loop of "add"s... clumsy, but would work. On 07/19/2017 03:39 PM, Mike Morris wrote: I am a newbie, but I think the answer is that you can't do that in the template - instead, calculate the number in the view and pass it to t
