You can use Mysql and Mongodb in one application.

1. Create a rails app using mysql.

2. Next, add following to your Gemfile, and run bundle install:

gem "mongoid", "~> 2.3"
gem "bson_ext", "~> 1.4"

Now, you’re almost ready to go, but you still need some configuration info. Generate config/mongo.yml by running:

rails generate mongoid:config

This will create a mongo.yml where you can configure it to use as per the development environment.

Configure Rails’ model generator. Inside of the Application class (config/application.rb)  add:

config.generators do |g|
  g.orm :mongoid
end

This will allow you to use the rails generate model command with Mongoid.
