New description:
When using djangorestframework with django 2.0.X with lookup _in like
{{{id__in=[1,2,3]}}} will raise: unhashable type: 'list'
traceback ends to this file:
{{{
/django/utils/tree.py" in __hash__
74. return hash((self.__class__, self.connector, self.negated) +
tuple(self.children))
}}}
When using tuples with {{{__in}}} everything works fine. But when using
.values_list() on query I need to use tuple(query) to use it in Q object
with {{{__in}}} lookup.
Code worked before with 1.11 version just fine. Also when using _in
without Q() everything seems to work just fine.
