The Delete controller motion is exactly the same since the former Shop Facts controller motion: it queries the album item in the database utilizing the id delivered within the URL and returns the suitable Look at. To achieve this, change the HTTP-GET Delete action approach code with the next:
In the next Component of the series, we critique the app and make some enhancements to the mechanically generated Facts and Delete techniques.
