sinatra-mongoid-config

Add Monogid to your Sinatra app with potentially zero-configuration. Lazily create the database connection whenever needed.

It‘s available as a gem via RubyGems.org, so use standard procedure:

$ gem install sinatra-mongoid-config

If you're using Bundler, just add gem "sinatra-mongoid-config" to your Gemfile.

This extension works fine with both “classic” Sinatra apps, as well as “modular” apps which inherit from Sinatra::Base. How you use the extension varies slightly between styles.

require 'rubygems'
require 'sinatra'
require 'sinatra-mongoid-config'

get '/' do
  'It works!'
end

require 'rubygems'
require 'sinatra'
require 'sinatra-mongoid-config'

class MyApp < Sinatra::Base

  register Sinatra::MongoidConfig

  get '/' do
    'It works!'
  end

end

All options are set using Sinatra’s standard set method. Remember that you can also change settings for each environment:

configure do
  set :mongo_db, 'the_database'
  set :mongo_port, 123
end

configure :production do
  set :mongo_db, 'the_other_database'
  set :mongo_user, 'the_user'
  set :mongo_password, 'the_password'
end

All configuration options have sensible defaults listed below, and depending on your situation, you may not have to set anything.

Did you notice that the default for :mongo_db calls self.app_to_db_name? That method attempts to be smart about what your database is named by using the class name of your app and the current environment. The real benefit here is for those who are creating "modular" apps, as they are named something other than the Sinatra default. Here are some examples:

• Dan Croak's sinatra-mongoid
• Ethan Gunderson's sinatra-mongo-config
