Question

I have a problem with setting up rails application. We use rails 3 (we also use memcached), and have I installed everthing (DB, ruby, rubygems, rails, …) and configure the DB. So if I run rails server the apllication starts ok.

For production we will use Apache and Phusion Passenger, both have been installed sucessfuly. When I restart apache I get this error:

First I thought that it might be sometnig with memcached, like some missing module for apache, but I read that there is no configuration needed for apache/passenger.

My question is, why application doesn’t start? Have I forgot to install or configure someting? I really don’t know what might be wronge since the application starts ok with rails server.

Tnx in advance 😉

Look at this file:

/media/Disc/ABC/CODE/TESTINGAPP/app/controllers/application.rb

Since Rails 2.3 this file should be called application_controller.rb and not application.rb. Rename the file and it should work:

/media/Disc/ABC/CODE/TESTINGAPP/app/controllers/application_controller.rb
