Why can't I do cascading includes in ruby on rails:
Tree.find(:first, :include => {:children => {:children => :children}})
I get an error for 3 cascading joins but not 2
I am wondering why you would need to pull all of that information at once? Could you not simply do the one include at first and simply for child in children.children later on when you need it? Can you give a example of why you are needing the cascading includes?
