Deleting
Deleting an object is as straightforward as creating or updating one. You simply define the object to delete and then call the delete() method.
For example, let's create a test author for deletion:
author4 = Author.objects.create(first_name='TestName', last_name='TestName')
Note
The
save()method isn't necessary here ascreate()already saves the object.
Now, our table has a new instance, and Author.objects.all() will show information about four authors.
The most common approach to delete is to retrieve the instance by its ID and then delete it:
Author.objects.get(id=4).delete()
No need to save the changes after deletion.
1. How do you delete an object in Django?
2. What happens when you execute Author.objects.get(id=4).delete() in Django?
3. After deleting an object in Django, what is required to reflect this change in the database?
