Rails will not let me destroy scaffolding from nifty generator

Question

I was following one of the railscasts tutorials and decided to install nifty generators. Well, being a rails noob I didn't realize that the way parameters are handled changed. Now I can't undo any of my changes. So far I managed to roll back the database but every time I try to run

rails destroy nifty:scaffold mymodel

I get the error message

attr_accessible is extracted out of rails into a gem. Please use new recommended protection model for params(strong_parameters) or add protected_attributes to your Gemfile to use old one.

So I did. I added

gem 'protected_attributes'

and ran

bundle install

Then I tried to destroy it and it errored out again. I really hope nifty didn't just screw up my project. Can anyone help?

Um, this not a real solution, but a possible workaround: if the output of the rails generate nifty:scaffold mymodel command is still in your terminal buffer, you could manually delete the files it created.

And if the output isn't available, you could do rails generate nifty:scaffold mymodel2 in order to see what files nifty:scaffold created before manually deleting the corresponding files for mymodel.

Not elegant, but it might get you over the hump.
