A Hashrocket project

Specify different bundler groups with RAILS_GROUPS

Is there a gem that you want to include sometimes and not others? For instance, do you have multiple versions of staging with slightly different gemsets? You can manage that with custom groups.

group :apple do
  gem 'some_gem'

group :orange do
  gem 'some_other_gem'
RAILS_GROUPS=apple,orange rails console
> Rails.groups
[:default, "development", "apple", "orange"]

In the config/application.rb file, Rails.groups is passed to Bundler.require.
