l例如写一个图书的管理页面，包括增删改查

首先创建model表

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=32)
    price = models.DecimalField(max_digits=8,decimal_places=2)
    date = models.DateField()
    publish = models.ForeignKey("Publish",on_delete=models.CASCADE)
    authors = models.ManyToManyField("Author")
    def __str__(self):  #在admin页面显示中文
        return self.title


class Publish(models.Model):
    name = models.CharField(max_length=32)
    def __str__(self):
        return self.name

class Author(models.Model):
    name = models.CharField(max_length=32)
    def __str__(self):
        return self.name
