django2.0新增功能流程
1先在 models.py中，创建字段相关的内容，我这里添加一个博客分类的表 定义数据结构的地方
class PostType(models.Model): title = models.CharField(max_length = 60) #分类标题 order = models.IntegerField() #排序 timestamp = models.DateTimeField() #创建时间
2 执行数据库同步
E:\python\mysite>python manage.py makemigrations blog Migrations for 'blog': blog\migrations\0004_posttype.py - Create model PostType
E:\python\mysite>python manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, blog, contenttypes, sessions
Running migrations:
Applying blog.0004_posttype... OK
3 通过Admin 管理
通过Admin后台来管理blog表数据。打开 admin.py 文件
from django.contrib import admin from blog.models import BlogsPost from blog.models import Member from blog.models import Link from blog.models import PostType #这个是新添加的 # Register your models here. class BlogsPostAdmin(admin.ModelAdmin): list_display = ['title', 'body', 'timestamp'] class MemberAdmin(admin.ModelAdmin): list_display = ['username', 'password', 'timestamp'] class LinkAdmin(admin.ModelAdmin): list_display = ['title', 'link', 'order', 'timestamp'] class PostTypeAdmin(admin.ModelAdmin): list_display = ['title', 'order', 'timestamp'] #这个是新添加的 admin.site.register(BlogsPost, BlogsPostAdmin) admin.site.register(Member, MemberAdmin) admin.site.register(Link, LinkAdmin) admin.site.register(PostType, PostTypeAdmin) #这个是新添加的
4 重启服务，打开后台进行访问
5 如果想放到线上，那么把文件都上传到服务器，然后执行数据恢复
[root@izwz90bp6do7s3cr45cw6az newblog]# python manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, blog, contenttypes, sessions
Running migrations:
Applying blog.0004_posttype... OK
6 重启uwsgi,然后登陆后台看下
杀掉端口进程，重新加载
fuser -k 8000/tcp
uwsgi --ini newblog.ini
7 登陆线上后台看看
添加测试，可以成功，有数据
OK，今天到这里，下一步，看看怎么把分类ID 弄到博客表里面
