match ‘ads/:id’ => :show

def show
@ad = Ad.find(params[:id])
end
def index
@ads = Ad.find(:all)
end

Firstly don’t use Rails 3 as it is not only obsolete but will go out
of support within a few months. As a beginner I suggest you work
right through a good tutorial (which uses the latest rails) such as
railstutorial.org (which is free to use online). That will show you
the basics or Rails.

As for your specific problem it should be /ads/show/3. Also the route
for index should not include the id. But in routes.rb you should be
using resources rather than match for such cases. As I said work
through the tutorial before going further.

The “show” route would just be /ads/3 : http://localhost:3000/ads/3
The “index” route is just /ads: http://localhost:3000/ads

That’s true, perhaps I need to work through the tutorial again myself :slight_smile:

I have the guides, the api docs, and Ruby’s Enumerable pinned in my
browser
for re-reading. :slight_smile:
