What is the equivalent of “none” in django templates?

Question

I want to see if a field/variable is none within a Django template. What is the correct syntax for that?

This is what I currently have:

{% if profile         


        

Answer 1

{% if profile.user.first_name %} works (assuming you also don't want to accept '').

if in Python in general treats None, False, '', [], {}, ... all as false.
