How to create a new environment in Ruby on Rails?

Question

I\'m trying to create a new environment (build) for using it with hudson.

I\'m doing this because I didn\'t want to mix up my test databases with hudson test databas

Updated Answer for Rails 5

Create new environment file:

config/environments/staging.rb

Modify the following files to add the environment key 'staging'

config/cable.yml
config/database.yml
config/secrets.yml
Gemfile (incase you have stage dependent gems)

The new environments can now be used as usual for eg:

rails server -e staging

rails console staging

Or to do conditional checks:

rails console staging, Rails.env.staging?

Good place to start for creating new environment and to modify these files is to copy production settings.
