#29838 closed Bug (fixed)

Hashing list in Q objects when using __in lookup

Description

This bug was previously reported here - #29643.

However I am still getting this error upon rendering QuerySets that use the Q object and include the __in filter in the most recent release of django, 2.1.2.

Here is my reproduction of the bug on master:

Code highlighting: 

>>> q = Q(a__in=[1, 2])
>>> q.__hash__()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/aspalding/Documents/django/django/utils/tree.py", line 89, in __hash__
    for child in self.children
TypeError: unhashable type: 'list'

Therefor the minimal reproduction for NodeTest would look like:

Code highlighting: 

hash(Node([('a', [1, 2])]))

Patch needs improvement: set
Severity: Normal → Release blocker
Triage Stage: Unreviewed → Accepted
Version: master → 2.0

It qualifies for a backport to stable/2.1.x since it's a regression in 508b5debfb16843a8443ebac82c1fb91f15da687.

In 217f82d7:

Refs #29838 -- Fixed make_hashable() for values that have lists or dicts nested in tuples.

And for non-hashable values that are iterable, e.g. sets.
