How to rename rails controller and model in a project

by

Here is what I would do:

Create a migration to change the table name (database level). I assume your old table is called corps. The migration content will be:

class RenameCorpsToStores < ActiveRecord::Migration
  def change
    rename_table :corps, :stores
  end
end

Change your model file name, your model class definition and the model associations:

  • File rename: corp.rb -> store.rb
  • Code of store.rb: Change class Corp for class Store
  • Rename all the model associations like has_many :corps -> has_many :stores

Change your controller file name and your controller class definition:

  • File rename: corps_controller.rb -> stores_controller.rb
  • Code of stores_controller.rb: Change class CorpsController for class StoresController

Rename views folders. From corps to stores.

Make the necessary changes in paths in the config/routes.rb file, like resources :corps -> resources :stores, and make sure all the references in the code change from corps to stores (corps_path, …)

Remember to run the migration 🙂

If previous is not possible, try to delete the db/schema.rb and execute:

 $ rake db:drop db:create db:migrate
