django - show the length of a queryset in a template

Question

In my html file, how can I output the size of the queryset that I am using (for my debugging purposes)

I've tried

{{ len(some_queryset) }}

but that didn't work. What is the format?

Answer 1

Give {{ some_queryset.count }} a try.

This is better than using len (which could be invoked with {{ some_queryset.__len__ }}) because it optimizes the SQL generated in the background to only retrieve the number of records instead of the records themselves.
