Description (last modified by )
As CallableBool has no hash method, membership test operations for sets do not work:
from django.utils.deprecation import CallableTrue
assert CallableTrue in {True}
TypeError: unhashable type: 'CallableBool'
Adding a hash method solves this problem:
def __hash__(self):
return hash(self.value)

Yes, seems strange. I ran into this issue using Django REST framework. When serializing user.is_authenticated it is runs through this check and fails.
Note:
See TracTickets
for help on using tickets.
It seems a bit odd to have such code, but I suppose it doesn't hurt.
