In routes.rb, your routes should be defined as below:

resources :people

This way people_path would be available. After this, you can run rake routes and check the routes created for you as below:

people      GET    /people(.:format)                     people#index
            POST   /people(.:format)                            people#create
new_person  GET    /people/new(.:format)             people#new
edit_person GET    /people/:id/edit(.:format)       people#edit
person      GET    /people/:id(.:format)                 people#show
            PATCH  /people/:id(.:format)                        people#update
            PUT    /people/:id(.:format)                        people#update
            DELETE /people/:id(.:format)                        people#destroy
