What would be a smart way to Add a comment form and lists comments on  
a per model base?

Im building a social networking site and would like to have comments  
on certain contents. I could add a comment form for every model  
manually but what would be a better way to have comments added on a  
per model base ? Where I could add something in the model and it would  
include the comments, + new comment form?

Thx!

A comment is a comment is a comment, and as such, you need only one  
comment form. You should read up on partials, and multi-part forms  
(railscasts [[http://railscasts.com/](http://railscasts.com/) ] has some very good episodes that  
would answer your questions IIRC.

If you want your comments related to multiple models, then you should  
look into polymorphic associations.

All eminently do-able in Rails.
