How to directly access MongoDB API from Mongoid?

[Volkan Unsal]

I'd like to use the addToSet method of MongoDB, but Mongoid doesn't
currently support this yet. Is there a way of directly accessing the
MongoDB driver from my Rails model?

Assuming your model object is a Mongoid::Document, simply call the
"db" method on it to get a handle to the Mongo::DB object that Mongoid
is using under the hood.

From there, you can use the MongoDB Ruby driver API directly.

Model.collection will get you the collection object.

In addition to the response by Durran, there is a ticket for adding addToSet functionality.
