Is there a rake command in Rails 3 to clone my development database data? I noticed rake db:test:prepare and rake db:test:clone are mentioned throughout various blogs, but running them seems to do nothing. Furthermore, rake -T shows no db:test cases. I've resorted to loading a sql dump for now, but it would be great if I could just clone...

Now to do this without any extende...

I cannot use _("string") right into model.to_liquid, because it doesn't work. As far as I understand, the model is loaded once, and it will always return the...

Product has a full scaffold while Photo has a photos_controller that I am working on. In routes.rb we have: resources :products (generated by the scaffold) As phot...
