-------------------------------+--------------------
I have two models one with an int pk and one with a UUIDField pk:
{{{
class Bar(models.Model):
id = models.UUIDField(primary_key=True, default=uuid4)
class Bar2(models.Model):
pass
}}}
If I try to get these using a value of {} they fail differently. The model
with the int pk:
{{{
>>> Bar2.objects.all().get(pk={})
TypeError: int() argument must be a string or a number, not 'dict'
}}}
whereas:
{{{
>>> Bar.objects.all().get(pk={})
