Python学习日志9：Django建立Blog Python3

由于大部分资料（比如《Django Web开发指南》）都是python2.x的
踩了很多坑，特此更新macOS环境下学习Django 建立Blog方法
1、安装Django
[>>>pip3 install django
Successfully installed django-2.0.7 pytz-2018.5
2、在目标文件夹终端创建自己的blog项目
[>>>django-admin.py startproject <projectname>
比如：
[>>>django-admin.py startproject abcBlog
3、校验本地服务器环境
[>>>python3 manage.py runserver

July 02, 2018 - 09:48:51
Django version 2.0.7, using settings 'abcBlog.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
[02/Jul/2018 09:49:02] "GET / HTTP/1.1" 200 16348
[02/Jul/2018 09:49:02] "GET /static/admin/css/fonts.css HTTP/1.1" 200 423
[02/Jul/2018 09:49:02] "GET /static/admin/fonts/Roboto-Bold-webfont.woff HTTP/1.1" 200 82564
[02/Jul/2018 09:49:02] "GET /static/admin/fonts/Roboto-Regular-webfont.woff HTTP/1.1" 200 80304
[02/Jul/2018 09:49:02] "GET /static/admin/fonts/Roboto-Light-webfont.woff HTTP/1.1" 200 81348
Not Found: /favicon.ico
[02/Jul/2018 09:49:02] "GET /favicon.ico HTTP/1.1" 404 1979

浏览器打开http://127.0.0.1:8000/ 查看debug环境 ctrl+C退出开始安装blogAPP

4、安装blog APP
[>>>python3 manage.py startapp blog
5、Setting文件配置

很多材料写<projectname>.blog，这种写法在django-2.0.7以上会报错
AttributeError: module <projectname> has no attribute 'blog'
数据库缺省

6、创建库表配置
models.py文件添加配置

from django.db import models
# Create your models here.
# 博客类由标题、主体、时间组成，分别使用char、Text、DateTime三种不同控件
class BlogsPost(models.Model):
    title = models.CharField(max_length=150)
    body = models.TextField()
    timestamp = models.DateTimeField()

admin.py文件添加管理界面配置

from django.contrib import admin
from blog.models import BlogsPost

# Register your models here.
class BlogsPostAdmin(admin.ModelAdmin):
    list_display = ('title', 'body', 'timestamp')

admin.site.register(BlogsPost, BlogsPostAdmin)

7、执行数据库同步创建表

[>>>python3 manage.py makemigrations blog

Migrations for 'blog':
  blog/migrations/0001_initial.py
    - Create model BlogsPost

[>>>python3 manage.py migrate

Operations to perform:
  Apply all migrations: admin, auth,  blog, contenttypes, sessions
Running migrations:
  Applying contenttypes.0001_initial... OK
  Applying auth.0001_initial... OK
  Applying admin.0001_initial... OK
  Applying admin.0002_logentry_remove_auto_add... OK
  Applying contenttypes.0002_remove_content_type_name... OK
  Applying auth.0002_alter_permission_name_max_length... OK
  Applying auth.0003_alter_user_email_max_length... OK
  Applying auth.0004_alter_user_username_opts... OK
  Applying auth.0005_alter_user_last_login_null... OK
  Applying auth.0006_require_contenttypes_0002... OK
  Applying auth.0007_alter_validators_add_error_messages... OK
  Applying auth.0008_alter_user_username_max_length... OK
  Applying auth.0009_alter_user_last_name_max_length... OK
  Applying sessions.0001_initial... OK
  Applying blog.0001_initial... OK

8、创建超级用户
[>>>python3 manage.py createsuperuser

Username (leave blank to use 'xxx'):
Email address: 
Password: 
Password (again): 
Superuser created successfully.

[>>>python3 manage.py runserver
浏览器打开http://127.0.0.1:8000/admin/

登录（刚才创建的账户密码）
登录界面
尝试发帖，这里用到的就是models.py里配置的BlogsPost
查看管理界面，这里用到的就是admin.py里配置的BlogsPostAdmin
