Does MongoMapper (or any other Mongodb adapter) have a method like "accepts_nested_attributes_for"?

Question

I am considering using mongodb in a new project, but before delving into it, I would like to know if it supports some key features. I know you don’t need migrations, and you can add embedded objects ... but does all this mean that it also behaves as if the accepts_nested_attributes_for method always exists?

Do you know of any other killer features that I should know about that will affect me or against MongoDB?

Here is a recent article that I know about, and that others may also be interested in:

Looks like the mongomapper guy is working on a solution to this:
