test

I want the URL to be /appointments/review/HSGy56GJS67 where the last part is a unique token that identifies the review

routes file
resources :appointments do
    collection do
      get 'review/:review_token', :to => 'appointments#review_appointments'
    end
  end

rake routes(first column is blank, there is no path for some reason like 'reviews_appointments')
GET        /appointments/review/:review_token(.:format)           appointments#review_appointments

html
<%= link_to "Rate your appointment", controller: "appointments", action: "review", review_token: @appointment.review_token %>

error
No route matches {:controller=>"appointments", :action=>"review", :review_token=>"IZ9ubwXxFLrFRsmwKYjKCQ"}
