Deleting Records

AppFolder \ views.py

all_notes = Note.objects.all(): Retrieves all Note objects from the database;
for i in all_notes:: Iterates through all Note objects in the QuerySet;
i.delete(): Deletes each Note object from the database;
return HttpResponse('Notes deleted'): Returns an HTTP response with the text message "Notes deleted".

Updating Records

AppFolder \ views.py

all_notes = Note.objects.all(): Retrieves all Note objects from the database;
for note in all_notes:: Iterates through all Note objects in the QuerySet;
note.title = 'LOL': Sets a new value for the title field of each Note object;
note.save(): Saves the changes to the database;
return HttpResponse('Notes updated'): Returns an HTTP response with the text message "Notes updated".

Please note that in update_content, we are changing the title field of each Note object to the value 'LOL'. You can adapt this code according to your specific requirements.
