I''m trying to implement the to_param method to allow url generation to be in the format of /:category_name/:article_permalink (as discussed on page 299 of Agile Web Development With Rails). I expect that I need to override/implement the to_param method and have it return the category_name for the category model and the article_permalink for my article model, but I haven''t had any luck in doing this. I''m sure it is a problem with the syntax... Can anyone help me out with an example? And as long as routes.rb has a matching map.connect the links generated by rails should match, correct?
