Django ORM Ninja: Advanced Techniques for Developers

bookDeleting

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 as create() 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?
