How to re-name a ActiveRecord Model which can automatically change the table name in DB?

Question

I have a Active Record model \"car\", I would like to change the name of this model to \"train\" without changing functionalities inside, that\'s only

Answer 1

I figured out the following way:

1, generate migration file:

rails generate migration rename_cars_to_trains

2. edit the created migration file to:

   class RenameCarsToTrains < ActiveRecord::Migration
     def self.up
       rename_table :cars, :trains
     end
   
     def self.down
       rename_table :trains, :cars
     end
   end
   

3. rake db:migrate

After these steps, the table name changed from cars to trains, then, I have to manually change the controller and views names and the associations...

If you have any more efficient way, let me know...
