Using Active Record generators after Mongoid installation?

I'm using MongoDB via Mongoid integration, as well as ActiveRecord in a project. I would like to gen开发者_如何转开发erate migrations for active record, and Mongoid is the default when I run.

rails g migration

Any ideas how to specify AR as my default generator for migrations, models, etc?

Thanks!

rails g active_record:migration 

You can config to use ActiveRecord generators in your config/application.rb

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