Merging Gems

Your workers can take advantage of the wealth of libraries that the Ruby community has produced, but it takes a little bit of setup.

Merging gems is simple in iron_worker_ng; you just use the gem command in your .worker file:

gem 'activerecord'
gem 'paperclip', '< 3.0.0,>=2.1.0'

The first parameter is the gem name, the second is an optional string of version constraints. See the .worker file reference for more information.

You can also use the gemfile command to merge gems from a Gemfile into your worker:

gemfile '../Gemfile', 'common', 'worker' # merges gems from common and worker groups
