Try setting the upsert parameter to true in your call to update. From the mongoid docs: http://docs.mongodb.org/manual/reference/method/db.collection.update/#update-parameter

Optional. If set to true, creates a new document when no document matches the query criteria. The default value is false, which does not insert a new document when no match is found.
