第一;,models.py建表
from django.db import models # Create your models here. class Book(models.Model): #必须继承models.Model这个类，jango才能识别Book是一张表 name=models.CharField(max_length=20)#charfield字符串类型，长度20 #price=models.FloatField() price=models.IntegerField () pub_date=models.DateField() author=models.CharField(max_length=32,null=False) class Author(models.Model): name=models.CharField(max_length=32)
第二 urls.py 建立连接
from django.conf.urls import url from django.contrib import admin from app import views urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'index',views.index), url(r'addbook',views.addbook), url(r'update',views.update), url(r'delete',views.delete), ]
第三：views.py 写处理函数
from django.shortcuts import render,HttpResponse from app.models import * # Create your views here. def index(request): return render(request,"index.html") def addbook(request): #Book，使用导入from app.models import * b=Book(name="java",price=99,author="qiqi",pub_date="1456-12-12") b.save()#save执行，则上面语句成功 #Book.objects.create(name="",。。。)另一种添加数据，不需要save return HttpResponse("添加成功") #要想此句需要from django.shortcuts import render,HttpResponse def update(request): Book.objects.filter(name="java").update(price="990")#修改方法一 # #修改方法二 # b=Book.objects.get(name="java")#拿到的b是列表类型是queryset集合的 # b[0].price=100 # b[0].save() return HttpResponse("修改成功") def delete(request): Book.objects.filter(name="java").delete() return HttpResponse("删除成功")
输入python manage.py rnserver 8800 访问127.0.0.1：8800/index
第四部：index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> .head{ line-height: 40px; background-color: green; color: white; text-align: center; } </style> </head> <body> <div class="outer"> <div class="head">标题</div> <div class="content"> <a href="/addbook/">添加书籍</a> <a href="delete">删除书籍</a> <a href="update">修改书籍</a> </div> </div> </body> </html>
