i have class foo embedded object bar. every time foo created, want bar created. bar initiated passing variables foo. how can accomplish this?

thanks

use before_create hook auto create bar. like

class foo   include mongo....   attr_reader :new_bar   before_create :create_bar    def create_bar     self.bars << new_bar   end end

that way can still validate bar (using new_bar or whatever want).

both mongomapper , mongoid have before_create hook, should fine in either.
