Django 博客系统----settings设置和表关系结构

settings设置

静态文件static目录:/blog/static

STATIC_URL = '/static/'
STATICFILES_DIRS=[
    os.path.join(BASE_DIR,"blog","static"),

media目录：/blog/media/uploads

MEDIA_ROOT=os.path.join(BASE_DIR,"blog","media","uploads")
MEDIA_URL="/media/"

数据库表结构：

1.用户信息表 UserInfo（继承AbstractUser）
    settings：
    AUTH_USER_MODEL = "blog.UserInfo"
2.站点信息表 Blog
3.站点分类表 SiteCategory
4.站点文章分类 SiteArticleCategory
5.文章表 Article
6.博主文章标签表 Tag
7.文章TO标签多对多表 Article2Tag
8.博主个人文章分类表 Category
9.文章内容表 ArticleDetail   
10.评论表 Comment
11.文章点赞表 ArticleUp
12.评论点赞表 CommentUp

通过admin插入数据：

在admin.py中导入models，admin.site.register(表名)

from blog.models import *

admin.site.register(UserInfo)
admin.site.register(Article)
admin.site.register(Blog)
admin.site.register(ArticleDetail)
admin.site.register(Category)
admin.site.register(Tag)
admin.site.register(Comment)
admin.site.register(CommentUp)
admin.site.register(ArticleUp)
admin.site.register(SiteArticleCategory)
admin.site.register(SiteCategory)
admin.site.register(Article2Tag)

设计表代码：

from django.db import models
# Create your models here.
from django.contrib.auth.models import AbstractUser
