我使用django rest框架和泛型api视图但是当我调用list api视图时它给了我AttributeError:'QuerySet'对象没有属性'_meta'错误.

下面是我的代码

models.py

class Book(models.Model):
    name = models.CharField(max_length=200, null=False, blank=False)
    cover = models.ImageField(upload_to=RenameFile('books', 'cover'), null=False, blank=False)
    author = models.ForeignKey(Author, null=False, blank=False)
    rating = models.DecimalField(decimal_places=1, max_digits=1, null=True, blank=True)
    blurb = models.TextField(null=False, blank=False)
    free_chapters = models.FileField(upload_to=RenameFile('books', 'free'), null=False, blank=False)
    free_chapters_no = models.CharField(max_length=5, null=False, blank=False)
    paid_chapters = models.FileField(upload_to=RenameFile('books', 'paid'), null=False, blank=False)
    paid_chapters_no = models.CharField(max_length=5, null=False, blank=False)
    paid_chapters_credit = models.CharField(max_length=255, null=False, blank=False)
    language = models.ForeignKey(Language, null=False, blank=False)
    genre = models.ManyToManyField(Genre)

    def __str__(self):
        return self.name
