一、建立app以後註冊css

settings.pyhtml

二、templates文件夾建立以及配置文件中的路徑配置前端

settings.pyjquery

三、django鏈接MySQL數據庫

1.配置文件配置django

2.__init__文件中書寫下面兩行代碼
bootstrap

四、靜態文件配置app

1.手動建立static文件夾ide

2. html頁面上動態解析接口前綴oop

五、建立類（建表）並執行數據庫遷移命令

from django.db import models

# Create your models here.

class Book(models.Model):
    title = models.CharField(max_length=32)
    price = models.CharField(max_length=32)
    publish_time = models.DateField(auto_now_add=True)

    publish = models.ForeignKey(to='Publish')
    authors = models.ManyToManyField(to='Author')



class Publish(models.Model):
    name = models.CharField(max_length=32)
    addr = models.CharField(max_length=32)

class Author(models.Model):
    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)
