Rails - Oct 2007 - polymorphic associations

If i have the string ''us_address'' how can I use that to create
an instance for a view?

@us_address = UsAddress.new

Also, does anyone have a URL for how to construct forms for use with polymorphic
associations?  Everything I''ve seen up to now only shows the model
relationships.  How do you prepare to use this association in a form? 
What''s the best way to know what partial to load based on what model a
particular association will use?

I need to use multiple address types, us, eu, etc.

Thanks,

Some peeps from IRC helped me with this yesterday, so for posterity:

@address_type = ''us_address''

@address = @address_type.camelize.constantize.new
