Sample/Dummy Data Generation in Rails 3

Is there a standard gem for 开发者_Python百科creating data for testing purposes for Rails 3?

I am interested in using Faker or Forgery but is there a better approach?

What is the best way to generate and use sample data?

The two I'd recommend using would be factory_girl_rails by Thoughtbot and faker. These are by far the best two for generating sample data.
