Django项目之图书馆项目
1.项目架构
2.表结构设计
from django.db import models # Create your models here. #作者详情表 class AuthorDeatil(models.Model): nid = models.AutoField(primary_key=True) birthday = models.DateField() telephone = models.BigIntegerField() addr = models.CharField(max_length=64) # 出版社表 class Publish(models.Model): nid = models.AutoField(primary_key=True) name = models.CharField(max_length=32) city = models.CharField(max_length=32) email = models.EmailField() # 书籍表 class Book(models.Model): nid = models.AutoField(primary_key=True) title = models.CharField(max_length=32) publishDate = models.DateField() price = models.DecimalField(max_digits=5, decimal_places=2) publish = models.ForeignKey(to="Publish", to_field="nid", on_delete=models.CASCADE) # 多对多关系表 authors = models.ManyToManyField(to='Author') def __str__(self): return self.title # 作者表 class Author(models.Model): nid = models.AutoField(primary_key=True) name = models.CharField(max_length=32) age = models.IntegerField() authordetail = models.OneToOneField(to="AuthorDeatil", to_field="nid", on_delete=models.CASCADE) def __str__(self): return self.name
3.Settings设计

5.视图设计
