Use the RCQRS library in your Rails 3 web app.
Add the following dependencies to your Rails app's Gemfile and then sudo bundle install
gem "uuidtools"
gem "yajl-ruby", :require => 'yajl'
gem "eventful"
gem "rcqrs"
gem "rcqrs-rails"
Add the following snippet inside application_controller.rb (ensuring it is protected) to allow each of your controllers to publish commands.
def publish(command)
Rcqrs::Gateway.publish(command)
end
Create a yaml config file with your event storage configuration named config/event_storage.yml (or copy the example in example/event_storage.yml).
##Generators
This plugin provides three generators to ease common tasks for generating commands, events and controllers using the CQRS pattern.
- rcqrs:command
- rcqrs:controller
- rcqrs:event
Usage is rails generate rcqrs:command <command name>
