[Facebooker-talk] problem doing a CRUD update?

[Tres Wong-Godfrey]

If you're using RESTful routes anyway, you could just try something  
like this:

link_to "Delete", article_path(article, :canvas => true), :confirm =>  
"Are you sure?", :method => :delete

Peep Code has a nice and free cheat sheet for Rails RESTful resource  
routes.
