I am configuring Mongoid for testing a gem that depends on Mongoid. The API docs give an example config:

Mongoid.configure do |config|
  config.allow_dynamic_fields = false
  config.use(name: "mongoid_test", host: "localhost", port: 27017)
end

However, I get undefined method 'use' for Mongoid::Config:Module. Browsing the code it looks like there's an easy way specifically designed for what I'm doing:

Mongoid.configure do |config|
  config.connect_to('mongoid_test')
end

Not sure if the docs are old or if I was doing it wrong. Just thought I'd mention it.
