What is the best way to add errors to render if a child resource is really what's having issues and not the parent resource? In english what I mean is the following.. imagine the following code:

@foo = Foo.new
foochild = Foochild.new
// break foochild somehow
@foo << foochild
@foo.save

now when I do:

format.xml { render :xml => @foo.errors }

I don't get anything about how foochild broke, meaning the error message is useless to the user.

How does one go about fixing this?
