Working with multiple objects on forms

Hi everyone,

I have been through all of the documentation that I can find for
creating
and updating multiple objects on one form including:
http://wiki.rubyonrails.com/rails/pages/HowToUpdateMultipleAssociatedFormElementsOnOnePageand
I’m not really happy with the solutions. Are there any helpers for
working with multiple objects that I am missing. I want to be able to
submit
and validate forms with multiple objects. I want this to include
updating
and creating. Creating should be able to handle a maximum number of
objects
or using ajax to add an infinite number of objects.

If there aren’t any cleaner ways of doing then I was thinking of trying
to
do a plugin.

Does anyone have any thoughts on this?

Thanks,
Carl.
