Answer 1

Your link_to will be using the route from resources :articles. If you want it to use the custom route you've defined, name the route, and then use that in your link_to:

# routes.rb
match '/articles/:id/:title' => 'articles#show', :as => :article_with_title

# articles/index.html.erb
link_to article.title, article_with_title_path(article, :title => article.title)

Also, you may want to consider looking into using friendly_id. It does this for you, but more transparently.
