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.
I fetched this definition from the official rails guide: A controller's purpose is to receive specific requests for the application. Routing decides which controller receives which requests. Often, there is more than one route to each controller, and different routes can be served by different actions.
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
In addition to Nobita answer you similarly need to change the test & helper class definitions & file names for corps
to store
. More Importantly you should change corps
to store
in your config/routes.rb file
So in total you're making changes to the Controller, associated Model, Views, Helpers, Tests and Routes files.
I think what you’ve seen suggested with destroy
& generate
is a better option. I’ve given an answer how to do this here: Rails : renaming a controlller and corresponding model
