Application configuration shouldn't be spread throughout your code base. Instead a much better place to put it is an external YAML file. See how to do that in this episode.


# config/initializers/load_config.rb
APP_CONFIG = YAML.load_file("#{RAILS_ROOT}/config/config.yml")[RAILS_ENV]

# application.rb
def authenticate
  if APP_CONFIG['perform_authentication']
    authenticate_or_request_with_http_basic do |username, password|
      username == APP_CONFIG['username'] && password == APP_CONFIG['password']
    end
  end
end
# config/config.yml
development:
  perform_authentication: false

test:
  perform_authentication: false

production:
  perform_authentication: true
  username: admin
  password: secret
