如何为第三表提供输入

Question

class Author(models.Model):
    name = models.CharField(max_length = 100)
    def __str__(self):
        return self.name
  
class Book(models.Model):
    title = models.CharField(max_length = 100)
    authors = models.ManyToManyField(Author)
    def __str__(self):
        return self.title

    In [5]: Author.objects.all()
Out[5]: <QuerySet [<Author: Shanmukh>, <Author: Shyam>, <Author: sai>, <Author: VICKYS>, <Author: Himayu>, <Author: Himanya>, <Author: Srinivas>, <Author: LASKARATOYIBA>, <Author: ISI>, <Author: JAMI>]>

请帮助解决这个问题我不明白如何将数据提供给第三表，它是id、bookid和authorid的组合。

Answer 1

如果你想要的是在书中添加一个作者。你可以用这个：

book.authors.add(author)

在官方文件中看到这个
