Answer 1

I used following steps to rename my model

In sublime text:

1. press cmd + shift + find and choose case-sensitive search (see left buttons). It will search word in whole project
2. search and replace 'Cars' to 'Trains'
3. search and replace 'Car' to 'Train'
4. search and replace 'car' to 'train'
5. rails generate migration rename_cars_to_trains

6. manually change following file names

   • cars_controller
   • car_helper
   • Model/ car.rb
   • all related files in test folder

7. change folder name in views: cars to trains
