It would be very easy to add new generator extensions in netbeans. Netbeans doesn't do it
automatically, you need to do it manually. I am using NetBeans ver 6.8 and installed nifty generators successfully in netbeans by following procedure:
1. Download gems file of ryanb's nifty generator freely available.
2. install in netbeans from tools->rubygems-> install Local
3. go to the directory C:\Program Files\NetBeans 6.8\ruby2\jruby-1.4.0\lib\ruby\gems\1.8\gems\rails-2.3.5\lib\rails_generator\generators\components. It shows all the generators available in netbeans.
4. go to the directory C:\Program Files\NetBeans 6.8\ruby2\jruby-1.4.0\lib\ruby\gems\1.8\gems\nifty-generators-0.3.0\rails_generators. It shows the nifty generators which you have just now installed.
5. Copy all nifty generators to components directory shown in step 3.
6. right click on project and click generate and you will find the udpated list of all new generators
