django2.0新增功能流程

1先在 models.py中，建立字段相關的內容，我這裏添加一個博客分類的表 定義數據結構的地方

class PostType(models.Model):
    title = models.CharField(max_length = 60) #分類標題
    order = models.IntegerField() #排序
    timestamp = models.DateTimeField() #建立時間

 

2 執行數據庫同步

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 經過Admin 管理

經過Admin後臺來管理blog表數據。打開 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 #這個是新添加的

# 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'] #這個是新添加的

admin.site.register(BlogsPost, BlogsPostAdmin)
admin.site.register(Member, MemberAdmin)
admin.site.register(Link, LinkAdmin)
admin.site.register(PostType, PostTypeAdmin) #這個是新添加的

4 重啓服務，打開後臺進行訪問

5 若是想放到線上，那麼把文件都上傳到服務器，而後執行數據恢復

[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 重啓uwsgi,而後登錄後臺看下

殺掉端口進程，從新加載

fuser -k 8000/tcp

 uwsgi --ini newblog.ini

 

7 登錄線上後臺看看

添加測試，能夠成功，有數據

 

OK，今天到這裏，下一步，看看怎麼把分類ID 弄到博客表裏面
