What you are seeing is evidence that there is a nested route in play. Have a
read of the Routing from the outside in Rails Guide, and note carefully what
happens when you do this:
resources :articles do
resources :comments
end
What do the URL helpers look like to navigate to a single article's comments,
or to an individual comment itself? Remember, there is no exposed /comments/123
URL possible once you do that scheme above.
