如何在django中检索模型中的特定属性

from django.db.models import Q

# 假设我们有一个名为Book的模型，其中包含title和author属性
class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100)

# 检索title为"Python编程"的书籍
books = Book.objects.filter(title="Python编程")

# 检索author为"John"的书籍
books = Book.objects.filter(author="John")

# 检索title为"Python编程"且author为"John"的书籍
books = Book.objects.filter(title="Python编程", author="John")

# 检索title为"Python编程"或author为"John"的书籍
books = Book.objects.filter(Q(title="Python编程") | Q(author="John"))
