  • 图书管理系统

    1、创建app之后注册

    settings.py

     2、templates文件夹创建以及配置文件中的路径配置

    settings.py

    3、django连接MySQL

    1.配置文件配置

    2.__init__文件中书写下面两行代码

     4、静态文件配置

    1.手动创建static文件夹

    2. html页面上动态解析接口前缀

     

     5、创建类(建表)并执行数据库迁移命令

    from django.db import models
    
    # Create your models here.
    
    class Book(models.Model):
        title = models.CharField(max_length=32)

        publish_time = models.DateField(auto_now_add=True)

        authors = models.ManyToManyField(to='Author')
    
    
    
    class Publish(models.Model):
        name = models.CharField(max_length=32)
        addr = models.CharField(max_length=32)

        name = models.CharField(max_length=32)
        age = models.CharField(max_length=64)
    
        author_detail = models.OneToOneField(to='AuthorDetail')
    
    class AuthorDetail(models.Model):
        phone = models.BigIntegerField()
        addr = models.CharField(max_length=32)
