Module: RubyStation::Helper::Rails

Defined in:
lib/ruby-station/helper/rails.rb

Overview

This module helps invoking Rails apps. During execution of the application, Rails writes data to many directories (db/, log/, tmp/). So this helper copies all the files into data_dir and invoke the app within the directory.

Be sure to run ‘rake db:migrate RAILS_ENV=produciton’ before you create the gem of your app.

Examples:

RubyStation::Helper::Rails.run
