sorting - Cannot sort foreign keys fields in django admin list -

i'm trying sort foreign keys in change list not working yet. (i have seen when clicking sorting in table, gets wrong when foreign keys)

class productvariantadmin(admin.modeladmin):     fields=["product", "test_software", "test_variables", "name", "description"]     list_display = ("name", "product", "test_software", "test_variables", "description")     search_fields = ["name"]     form = productvariantform      def formfield_for_foreignkey(self, db_field, request, **kwargs):         print db_field.name         if db_field.name == "test_software_id":             kwargs["queryset"] = testsoftware.objects.all().order_by('name')         return super(productvariantadmin, self).formfield_for_foreignkey(db_field, request, **kwargs) 

i have seen work formfield_for_foreignkey, still list sorted id , not name of foreign key.

any solution that? i'm using django 1.4.1.

formfield_for_foreignkey overrides drop down menu.

what want order in model's meta:

 class testsoftware(models.model):       class meta:            ordering = ['name']
