The Indentation error is related to the spaces you have when you write your
code.
Based on looking at what you copy/pasted
The indentation of your def get_queryset is different from your other
def’s.
Python is very picky of how much or how little you indent your code for
good reason.
Everything that is nested inside something else should be 4 spaces or a tab
in. For example a def should be 4 spaces in from its class, a variable
should be 4 spaces in from its def.
IndentationError: unindent does not match any outer indentation level
