genres is still at this point an empty dictionary, so looking up
anything in it will fail. You seem to have missed a step in
constructing your lookup dictionary, try something like this:

genres = dict(Genre.objects.all().values_list('GenreType', 'id'))

PS: When asking for help on here, and you have an exception with some
code, the traceback that follows the exception provides exact log of
how and where the exception was raised. In this case, it would have
pointed out precisely which line the KeyError occurred. In this case,
it was obvious what was wrong, in other cases it may not be so
obvious, so in future please do include the full traceback to assist
the people you are asking to help you.

Cheers
