OK so I’ve been trying to follow the tutorial here:  
[http://rails.homelinux.org/](http://rails.homelinux.org/)

When I simply do “scaffold: category” in the controller.rb, everything  
works fine. BUT after I generate the controllers and other files using  
scaffold AS A SCRIPT (script/generate scaffold categories), DESTROY (or  
DELETE) does not work for any record in a table. This is the error I  
got:

What does it mean? Any ideas if this is a bug on Rails or Ruby?

Thanks!

The controller is verifying that destroy is invoked via post. A good  
thing because then Web crawlers won’t be likely to randomly delete  
rows from your database. But… it sounds like you have a link to  
destroy from your view and that link is issuing a get request.
