title: Does MongoMapper (or any other Mongodb adapter) have a method like "accepts_nested_attributes_for"?
body: <p>I'm considering using mongodb on a new project, but before delving in, I'd 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 that mean it also behaves as if the 'accepts_nested_attributes_for' method is always there?</p>
  
  <p>Do you know of any other killer features that I should be aware of that would sway me for or against MongoDB?</p>
