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')

git checkout master 

backup master: git branch backup

Make a new branch from your head.: git branch test

Switch to that and delete the old branch name.: git checkout test
git branch -D master

Checkout the last clean rev from your fork.:  git checkout master
