I started a Rails app and everything works fine. But now, I would like to rename a controller and the associated model:
I wanted to change the Corps
controller to Stores
and the same (without final s) for the model.
Looking on google, people suggested to destroy and then generate again the controller and model. The problem is that it will erase the actual code of each files!
Any solution? Thanks in advance.
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:
corp.rb
-> store.rb
store.rb
: Change class Corp
for class Store
has_many :corps
-> has_many :stores
Change your controller file name and your controller class definition:
corps_controller.rb
-> stores_controller.rb
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
