application_config functionality¶ ↑

‘application_config’ eases project configuring by introducing erb enabled yaml config file in RAILS_ROOT/config folder and provides handful methods accessing config values based on current rails environment. So, you can have separate sets of configuration properties for each rails environment you use.

Installation¶ ↑

gem “cleverua_application_config”, “~> 2.0”, :require => “application_config”

Then run:

rails generate application_config:install

Default configuration file¶ ↑

During installation plugin will create default config in RAILS_ROOT/config/application_config.yml, it looks like the following (please note it’s okay to put ERB tags in there)

development: &defaults
  items_per_page: 25
  secure_with_basic_auth: false
  base_url: development.com
  erb_enabled_property: <%= "#{Rails.root}/something" %>
test:
  <<: *defaults
  base_url: test.com
production:
  <<: *defaults
  base_url: production.com

Usage¶ ↑

You then can access those values using ‘property’ method:

class FooController < ApplicationController
  def index
    @base_url = property(:base_url)
  end
end

This will set @base_url with value ‘development.com’ if you run that in development environment.
