You have one perfectly good method and you want another one instead? :-)
Seriously, use get(pk=my_obj.pk). It's designed to retrieve single
instances from the database. You could do
filter(id=my_obj.pk).values("field_1", "field_2", ...)
but it's not going to be significantly faster unless your model has
massive fields (leading to other problems) and it reads a bit less
comprehensibly in the code.
