Define the general view
Modify the AuthorInfo class in the book/models.py code. If it is consistent, there is no need to modify it
class AuthorInfo(models.Model):
id = models.CharField(max_length=30, verbose_name="身份证号", primary_key=True)
name = models.CharField(max_length=20, verbose_name="姓名")
telephone = models.CharField(max_length=20, verbose_name="联系方式")
age = models.IntegerField(verbose_name="年龄", default=30)
sex = models.CharField(max_length=2, verbose_name="性别", default="男")
def __str__(self):
return self.nameinbook/views.py Create a new AuthorListView function under the file
