home.html
cv大法根据需求修改bootstrap导航栏的代码!
在get请求首页页面时,传递的locals()中是包含了request的,通过request可以取得session中的username值;
借此可以判断用户是否登陆!! 用Django的模版语法if-else-endif进行不同的展示!!
Ps: 退出登陆后,跳转登陆页面,发现浏览器里还有sessionid的存在,不要惊讶,这个是渲染登陆页面时验证码的session!!!

# 首页页面搭建

创建超级用户、完善admin.py;
登陆后台管理, 先添加文章表、标签表(除了评论表、点赞点踩表)等的模拟数据!
记得为已经注册的用户完善与站点表的外键关系!

在模版里拿到了文章对象,通过正反向查询,从文章表跨到站点表再跨到用户信息表,取到想要的数据!!

admin.py

from django.contrib import admin

from app01 import models

admin.site.register(models.UserInfo)     # -- 用户表
admin.site.register(models.Site)         # -- 站点表
admin.site.register(models.Tag)          # -- 标签表
admin.site.register(models.Category)     # -- 分类表
admin.site.register(models.Article)      # -- 文章表
admin.site.register(models.Article2Tag)  # -- 文章2标签表
admin.site.register(models.UpdandDown)   # -- 点赞点踩表
admin.site.register(models.Comment )     # -- 评论表
