Description
PEP 8 says:
"Comparisons to singletons like None should always be done with 'is' or 'is not', never the equality operators."
I don't know if it's a bug or a new feature, but {% if something is None %} doesn't work.
Note:
See TracTickets
for help on using tickets.
PEP 8 is about Python; it doesn't apply to the Django template language. The DTL doesn't attempt to mimic Python.
See the "Philosophy" note at the beginning of the template docs.
