实现环境表结构：

models.py表单创建与代码

from django.db import models# Create your models here.class Publisher(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=64,null=False,unique=True) def __str__(self): return "publisher_name:{}".format(self.name)class Book(models.Model): id = models.AutoField(primary_key=True) title = models.CharField(max_length=128,null=False) publisher = models.ForeignKey(to=Publisher) #外键关联 def __str__(self): return "book_title:{}".format(self.title)class Author(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=16,null=False) book = models.ManyToManyField(to="Book") #跟BOOK多对多关系 def __str__(self): return "author_name:{}".format(self.name)
