AttributeError: 'super' object has no attribute '__iter__'

[Anton-Shutik]

Hi, Thanks for great django addon!

I have models like this:

class VariantManager(QueryablePropertiesManagerMixin, models.Manager):
    pass

class Variant(models.Model):
    name = models.CharField()

    objects = VariantManager()

class StockLevel(models.Model):
    variant = models.ForeignKey("Variant")

And exception can be raised with:

variants = Variant.objects.filter(id=1)
stocklevels = StockLevel.objects.filter(variant__in=variants)

StackTrace:

django==3.2.23
django-queryable-properties==1.9.1

Looks like the issue when Im filtering on a FK that has QueryableManager.

Do you have any idea what can be wrong here ?

Thanks in advance

Thanks for the report.

I was able to reconstruct your case and identify a bug - it seems like using querysets with the queryable property extensions in __in subqueries was broken when support for raw queries was added. I'll try to implement a fix and publish a new version soon.

In the meantime, you could try to use django-queryable-properties==1.8.5 as that was the last version without support for raw queries, so it shouldn't contain the bug.

The bug should now be fixed in version 1.9.2, which was just released.

Yeah, works for me! Thank you so much for quick fix!
