12768	Raw query map problem with some primary keys	Reflejo@…	nobody	"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')
