Django项目：搭建博客

此次为0前端基础下的博客搭建，重点在于功能与内部逻辑方面

实现的功能：1.用户注册登录已经用户登录状态的保持（这里不用Django自带的user，是自己写的）

2.用户发表博文

3.基本的博客分类、博客分支页面的搭建。

页面代码较多，若要了解详细内容请访问我的GitHub链接

首先代码先贴出来

views.py

from django.shortcuts import render,render_to_response
from .models import *
import time
# Create your views here.

        if (len(UserResult)>0):
            FailRegisterResult = '用户已存在！'
            return render(request,'myblog/register.html',{'failregisterresult':FailRegisterResult})
