The MongoDB classes do not come with default generators for Rails applications. In order to use the rails generate commands, you can use the indirect rails3-generators project available at https://github.com/indirect/rails3-generators/#readme

Installation:

  1. Download the generators into your application’s lib folder:
    cd myapp
    git clone git://github.com/indirect/rails3-generators.git lib/generators`
    
  2. Install the rails3-generators gem
    gem install rails3-generators
    
  3. Add this to your project’s Gemfile
    gem 'rails3-generators'
    

Usage:

rails generate model ModelName --orm=mongo_mapper
