Where do you store your Rails Application's version number?

Question

We use the wonderful semantic versioning paradigm when versioning our rails app. One question I had was where is it best to store this number? I\'ve seen it stored in /l

Answer 1

My strategy is to let your VCS tags do it for you (git shown here).

Add this to your application.rb:

# Only attempt update on local machine
if Rails.env.development?
  # Update version file from latest git tag
  File.open('config/version', 'w') do |file|
    file.write `git describe --tags --always` # or equivalent
  end
end

config.version = File.read('config/version')

You can then access the version anywhere in your app with Rails.configuration.version

Answer 2

Personally I prefer adding a constant to the application class.

# file: config/initializers/version.rb
class SomeApp::Application
  Version = '1.0.0'
end
