How to create a new environment in Ruby on Rails?

by

Assuming you want create the hudson environment.

  1. Create a new environment file in config/environments/hudson.rb. You can start by cloning an existing one, for instance config/environments/test.rb.
  2. Add a new configuration block in config/database.yml for your environment.
  3. Update any other configuration file you might have under the config folder with your new environment, some gems create their own ymls under the config folder.
  4. That’s all.

Now you can start the server

rails server -e hudson

or run the console

rails console hudson

And so on.

If you are using an older version of Rails, the commands are

ruby script/server -e hudson
ruby script/console hudson
