在Django ORM中的ManyToMany关系模型之间创建查询

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField('Author')

class Author(models.Model):
    name = models.CharField(max_length=100)

book = Book.objects.get(id=1)
authors = book.authors.all()

author = Author.objects.get(id=1)
books = author.book_set.all()

book = Book.objects.get(id=1)
author = Author.objects.get(id=1)
book.authors.add(author)

book = Book.objects.get(id=1)
author = Author.objects.get(id=1)
book.authors.remove(author)

authors = Author.objects.filter(book__title__contains='Python')
