Question

Is there any convention about how/where to specify application’s version number?

For example, for the ruby gems lib/mygem/version.rb is the file generally used for that purpose.

My guess would be creating config/version.rb file like that:

module MySite
  VERSION = "0.0.4"

  # or in MySite::Application class
  # 
  # class Application
  #   VERSION = "0.0.4"
  # end
end

Answer 1

I will reply my own question, I was not able to find a better answer.

Since Rails application is basically MySite::Application I thought app’s version should be accessed by MySite::Application::VERSION so create :

config/initializers/version.rb

module MySite
  class Application
    VERSION = "0.0.4"
  end
end

or config/version.rb and require this file from config/application.rb
