How can I use ajax to add nested attributes dynamically into the form of an object?
I followed the railscast : #74 Complex Forms Part 2 - RailsCasts
but I'd like to use Ajax instead because the method above is sort of ugly.
Have you seen #196 Nested Model Form Part 1 - RailsCasts and part 2? It does not use ajax but I would not describe it as ugly.

yes I'm currently using those last railscasts methods but it's getting pretty difficult to use the method in the edit form.
I am trying to follow an ajax method that should insert a new nested attirubte form upon clicking a submit button in a form_remote_for. I put this in the create.rjs
association = :treatments new_object = @sample.class.reflect_on_association(association).klass.new
fields = :new_sample.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end
page.insert_html :bottom, :sample, fields
but I don't know how I can refer to the parent object's form in order to call field_for. ":new_sample" doesn't work. Any ideas?

No, actually, you don't want to use Ajax here. That will mean a round trip to the server each time you want to add a field. Bad idea. This should all be done on the client side.
Best,
