Tôi đã cố gắng tạo một dự án django có người dùng và những người dùng đó có thể thêm tiêu đề sách mà họ đã tạo. Nhưng mỗi khi tôi nhập tiêu đề cuốn sách (không phải trên trang quản trị) tôi nhận được lỗi nàyKhông thể gán phải là một cá thể. Django
Cannot assign "u'Hello Wold'": "Scripter.title" must be a "Book" instance.
