class BookUpdateView(UpdateView):
    model = Book
    fields = ['title', 'author']

💡 Hint

Common Mistakes

Using incorrect template paths

Wrong named URL in success_url

Not referencing the correct view class in urls.py

The template_name should point to the form template. The success_url uses the named URL for the book list. The URL pattern uses the BookUpdateView class.
