创建模型

在子应用的models.py中创建，如下：

from django.db import models

# Create your models here.
from django.db import models


class BookInfo(models.Model):
    name = models.CharField(max_length=15)

    def __str__(self):
        return self.name
    pass


class PeopleInfo(models.Model):
    name = models.CharField(max_length=15)
    gender = models.BooleanField()
    book = models.ForeignKey(BookInfo,on_delete=models.CASCADE)
    pass
