Is it possible to delete an embedded document in Mongoid without saving?

Question

Definitely related to this question , but since there was no answer, I feel I have to ask again. Is there a way to remove an inline document from a Mongoid embeds_many relationship without saving?

I want to change the array of embedded documents in memory - and then save all the changes with a single UPDATE operation. In particular, I would like to:

• Change arrays of embedded documents (add embedded doc / remove embedded doc / edit embedded doc / etc).
• Other changes to TLDs are possible.
• Save all changes with a single database call.
