Ruby on Rails 3, scaffold_controller not works, solution with Niftygenerators

As I tried to use scaffold_controller on Ruby On Rails 3, to create controller and view, and generated code was not working, I tried niftygenerators and they work.
This is how you can use them:
Edit you Gemfile (in root of your project) and add

gem "nifty-generators", :group => :development

after that, you can run

bundle install

to install gem

After that, you can do

rails g nifty:scaffold ModelName

and after that we must create layout:

rails g nifty:layout

That will successfully create controller and view from your ActiveRecord.
