tbcooney PRO said almost 3 years ago on Tracking Changes on Action Text :
I think it wouldn't justify it's own controller, and `restore` could be an action on the `Document::VersionsController`. The route might look like this, but I'm not sure what the logic in that method would look like.

# config/routes.rb
  resources :articles do
    scope module: 'articles' do
      resources :versions do
        post :restore, on: :member
