environment_configurable

Description

A library that makes environment dependent configuration easy in rails.

Rationale

Environment dependent configuration is a common problem in rails, and we noticed a common pattern:

• We tend to extract configuration variables to a yaml file
• We often wrap the yaml configuration in a configuration helper

Environment Configurable accomplishes both of these task succinctly.

Install

• gem install environment_configurable
• Add config.gem "environment_configurable" to your environment.rb file

Dependencies

• Rails 2.3.0 >=

Example

class S3Helper
  include EnvironmentConfigurable
  configure_with "config/s3.yml"

  def self.connect!
     AWS::S3::Base.establish_connection!(
        :access_key_id     => config.access_key_id,
        :secret_access_key => config.secret_access_key
      )
  end
end

s3.yml

production: &DEFAULTS
  access_key_id: ACCESS_KEY_ID
  secret_access_key: SECRET_ACCESS_KEY
  bucket: the-prod-bucket

staging:
  <<: *DEFAULTS
  bucket: the-staging-bucket

development:
  <<: *DEFAULTS
  bucket: the-development-bucket

test:
  <<: *DEFAULTS
  bucket: the-test-bucket
