(Django version 1.7.7)
I'm getting an assertion error on the first line of
`Query.change_aliases`:
assert
set(change_map.keys()).intersection(set(change_map.values())) == set()
Problem is, I can't post more data, because the queryset has confidential
client information :(
I can post the value of `change_map`, with identifying details renamed:
{'T5': 'T10',
'T6': 'T11',
'T8': 'T13',
'my_app_follow': 'my_app_follow',
'my_app_stack__readers': 'T7',
'my_app_stack__writers': 'T9',
'my_app_user': 'T8'}
This happened when doing `&` on two querysets, one of which having
`.distinct()` applied on it, among other things.
