Question

Started working with RoR again! I’m having trouble getting my config/routes.rb file to perform. I’m getting “uninitialized constant ApplicationsController” using RubyMine.

Here’s what I have changed in my routes.rb after trying to search things down:

resources :applications  
root :to => 'applications#index'

application_controller.rb has:
  class ApplicationController < ActionController::Base
  protect_from_forgery
end

I’ve ran my rake routes:

    applications GET    /applications(.:format)          applications#index
                 POST   /applications(.:format)          applications#create
 new_application GET    /applications/new(.:format)      applications#new
edit_application GET    /applications/:id/edit(.:format) applications#edit
     application GET    /applications/:id(.:format)      applications#show
                 PUT    /applications/:id(.:format)      applications#update
                 DELETE /applications/:id(.:format)      applications#destroy
            root        /                                applications#index

rake rails:update and all changes were approved except altering routes.rb
Heres what its kicks out Rubymine side:

Started GET "/" for 127.0.0.1 at 2012-11-11 02:50:27 -0800
Connecting to database specified by database.yml

ActionController::RoutingError (uninitialized constant ApplicationsController):

Thanks for the help!

Check if you have a file called applications_controller in your app/controller folder, or its name is application_controller, so rename it to applications_controller, if you don’t have that file, then create your ApplicationsController:

rails generate controller applications
