Creating a book record with attached covers – option 4

The create_book function is responsible for creating an instance of the Book model and its related BookCover records based on the provided validate_data dictionary. It first extracts the list of cover data from the dictionary, then creates a book object, and subsequently creates cover objects in a loop, associating them with the newly created book. A code review is needed: check for syntax correctness, proper data passing, potential optimizations, and possible errors.

def create_book(validate_data: dict):
    covers: list[dict] = validate_data.pop('covers')
    book = Book.objects.create(**validate_data)
    for cover in covers:
        BookCover.objects.create(**cover, book_id=book.id)
