MongoDB DBRef ON DELETE CASCADE

Question

Is there a way in MongoDB to have a foreign key with a 'ON DELETE CASCADE' functionality?

I know you can use DBRef as a sort of foreign key but when the item in a collection where the reference points to is removed, the reference returns null. But i want that the item where the reference belongs to gets removed. How do i do this?

Or do i need every time i remove things check references to it?

This feature doesn't exist now. If you want it. Add it on MongoDB Bugtracker
