#26264: values_list with flat=True doesn't make sense with prefetch_related
----------------------------------------------+--------------------
Reporter: agmond | Owner: nobody
Type: Bug | Status: new
Component: Database layer (models, ORM) | Version: 1.8
Severity: Normal | Keywords:

Assuming these models:
{{{#!python
class Temp(models.Model):
pass
class TempUuid(models.Model):
uuid = models.UUIDField(default=uuid.uuid4, editable=False)
temp = models.ForeignKey(Temp)
}}}
The result of the following code:
{{{#!python
>>> temp = Temp.objects.create()
>>> TempUuid.objects.create(temp=temp)
>>> TempUuid.objects.prefetch_related('temp').values_list('uuid',
flat=True)
}}}
is:
{{{#!python
TypeError: UUID objects are immutable
}}}
Note that there's no exception when removing the `flat=True`.
