Hello,
I'm trying the new raw query feature and i'm facing this bug:
When my model has primary_key set to some ForeignKey and I try to invoke
the raw() method, !InvalidQuery('Raw query must include the primary key')
is raised.
{{{
class ExampleModel(models.Model):
some = models.ForeignKey(SomeOther, primary_key=True)
class Meta:
db_table = 'example_model'
ExampleModel.objects.raw("SELECT some_id FROM example_model")
}}}
The problem arise because get_attname_column gives (some_id, some_id) as
name/column but then it is compared to _meta.pk.attname (some) here:
{{{
if skip:
if self.model._meta.pk.attname in skip:
raise InvalidQuery('Raw query must include the primary
key')
}}}
