title: Ruby on Rails Application Page Does Not Exist in Heroku Production Environment
body: <p>In my app during testing on <code>localhost</code> I am able to click on a link that brings me to the <code>edit_event_path(event)</code> page and it works perfectly.</p>
  
  <p>When I pushed it to Heroku I keep getting the error "This page does not exist" however I am still able to access the <code>/event</code> index page. </p>
  
  <p>It only appears to be for the edit page.</p>
  
  <p>My routes.rb</p>
  
  <pre><code>Rails.application.routes.draw do
    resources :approvals
    devise_for :users
    resources :events
  
    resources :roles
    # The priority is based upon order of creation: first created -&gt; highest priority.
    # See how all your routes lay out with "rake routes".
  
    scope "/admin" do
      resources :users do
        collection do
          match 'update_collection', via: [:put, :patch]
        end
      end
    end
    # You can have the root of your site routed with "root"
    root 'events#index'
  
    # Example of regular route:
    #   get 'products/:id' =&gt; 'catalog#view'
  
    # Example of named route that can be invoked with purchase_url(id: product.id)
    #   get 'products/:id/purchase' =&gt; 'catalog#purchase', as: :purchase
  
    # Example resource route (maps HTTP verbs to controller actions automatically):
    #   resources :products
  
    # Example resource route with options:
    #   resources :products do
    #     member do
    #       get 'short'
    #       post 'toggle'
    #     end
    #
    #     collection do
    #       get 'sold'
    #     end
    #   end
  
    # Example resource route with sub-resources:
    #   resources :products do
    #     resources :comments, :sales
    #     resource :seller
    #   end
  
    # Example resource route with more complex sub-resources:
    #   resources :products do
    #     resources :comments
    #     resources :sales do
    #       get 'recent', on: :collection
    #     end
    #   end
  
    # Example resource route with concerns:
    #   concern :toggleable do
    #     post 'toggle'
    #   end
    #   resources :posts, concerns: :toggleable
    #   resources :photos, concerns: :toggleable
  
    # Example resource route within a namespace:
    #   namespace :admin do
    #     # Directs /admin/products/* to Admin::ProductsController
    #     # (app/controllers/admin/products_controller.rb)
    #     resources :products
    #   end
  end
