Rails - Mar 2006 - Newbie question: Dynamic view creation from obj.to_html_form

Hi.  I would like to be able to generate a form dynamically from an 
object''s to_html_form method, submit it, and then place marshalled 
object into a database row.

Since I do not know exactly all the input fields in advance, I figure 
this would allow me to dynamically create the input form, stuff the user 
input into object, marshal  the object into the database, and display it 
later dynamically for the user to edit again.

I actually need to use the composite design model and so I will perhaps 
have nested objects with form information.  I should be able to marshal 
and unmarshal these objects without difficulty.

How do I do this in Rails?  This would be pretty cool because I could 
all sorts of  objects and their associated forms in the same table.  I 
could have a column for class name to iterate through all the same 
objects that I am interested in.

Thanks.

OK, I found the "Making Dynamic Templates" section in Agile Web 
Development with Rails.  I think that should explain it.  Has anyone 
created a dynamic template?

Thanks.
