For this django project, I would like to insert the new record on the database list after adding a record from the admin panel. It works if I clicked save record in the admin panel but however the current new record cannot be added into the database on http://127.0.0.1:8000/index/1/. May I ask if I would like to have the record being inserted anything I am missing?
