Disable database in Rails3?

You used to be able to disable the database for simple apps by putting:

config.frameworks -= [ :active_record, :active_resource, :action_mailer
]

in the config/environments.rb file..

How do you do this in rails3?

I see this in the top of config/application.rb

Pick the frameworks you want:

require “active_record/railtie”
require “action_controller/railtie”

require “action_mailer/railtie”
require “active_resource/railtie”
require “sprockets/railtie”

require “rails/test_unit/railtie”

So, you might experiment with commenting out the

require “active_record/railtie”

line?

On a fresh 3.2.1 project, created as such

$ rails new -T -d postgresql

I commented out require rails/test_unit/railtie

I was able to pass rake environment with these changes:
