By default, RubyOnRails let you have 3 databases, development, test and production. Can we add more databases in this file? Is there any limitation?
Can we change RAILS_ENV to 'beatlemania', add a matching item to the config/environment folder and the database.yml file?
Under Rails, I suspect the answer is yes, because Convention over Configuration allows the system to minimize all its configuration systems. But I suspect nobody ever needed to do this.
You are not asking for a new concept, beyond the natural trinity of test, develop, and produce. You are just asking for alternate databases. Toke some eRB:
production: adapter: mysql database: rails_production
database: <%= ENV['RAILS_DB'] %>
Now set that environmental variable (in the environment, or in config/boot.rb if you can't access the environment).
