A Better Mongoid Sinatra configuration implementation. Using settings hash for db options sucks!

mongoid3_sinatra_config.rb

# This is a modification of the blogpost on how to use Mongoid and Sinatra.
# Here is the original blogpost http://www.garrensmith.com/2010/09/11/Mongoid-sinatra.html
# The modification lets you use Mongoid 3.0 with the new Moped driver

# The new Moped driver uses the Sessions component to define the MongoDB connection rather
# than the Mongo::Connection.new that is used in the case of the default Ruby driver.
# Moped::Session.new vs Mongo::Connection.new

# Mongoid.load!(yaml_config.yml) is used to build the config hash. Alternatively, the hash can
# be built manually by using Mongoid.config {|config| ...} syntax. The config.sessions hash 
# contains the session information. The config hash has three main components: the session
# name (by default, its :default), the hosts that run the MongoDB instances (specified by 
# :hosts) and the database to connect (specified by :database). 
# Username and password, if present should also be defined via respective keys.

require 'sinatra'
require 'mongoid'

configure do
  Mongoid.configure do |config|
    config.sessions = { 
                        :default => {
                                      :hosts => ["localhost:27017"], :database => "my_db"
                                    }
                      }
  end
end

class User
  include Mongoid::Document
  field :name
  field :age
end

get '/' do
  User.find.count # returns the total number of users.
end

saved my ass, thanks
