Example models:
{{{
class ModelA(models.Model):
name = models.CharField(max_length=100)
class ModelB(models.Model):
model_a = models.ForeignKey(ModelA, on_delete=models.CASCADE)
value = models.IntegerField()
}}}
And with the following instances:
{{{
modelA = ModelA.objects.create(name='Test')
ModelB.objects.bulk_create([ModelB(model_a=modelA, value=1),
ModelB(model_a=modelA, value=2)])
}}}
The following query results in `AttributeError: 'ArrayField' object has no
attribute 'model'`
{{{
ModelA.objects.values('name').annotate(values=ArrayAgg('modelb__value')).order_by('values__0')
}}}
This crash also happens at least as far back as Django 4.2
