由于大部分資料（比如《Django Web開(kāi)發(fā)指南》）都是python2.x的
踩了很多坑换途，特此更新macOS環(huán)境下學(xué)習(xí)Django 建立Blog方法
1娱据、安裝Django
[>>>pip3 install django
Successfully installed django-2.0.7 pytz-2018.5
2胶果、在目標(biāo)文件夾終端創(chuàng)建自己的blog項(xiàng)目
[>>>django-admin.py startproject <projectname>
比如：
[>>>django-admin.py startproject abcBlog
3荒适、校驗(yàn)本地服務(wù)器環(huán)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.

瀏覽器打開(kāi)http://127.0.0.1:8000/ 查看debug環(huán)境 ctrl+C退出開(kāi)始安裝blogAPP

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

很多材料寫(xiě)<projectname>.blog页滚，這種寫(xiě)法在django-2.0.7以上會(huì)報(bào)錯(cuò)
AttributeError: module <projectname> has no attribute 'blog'
數(shù)據(jù)庫(kù)缺省

6崔步、創(chuàng)建庫(kù)表配置
models.py文件添加配置

from django.db import models
# Create your models here.
# 博客類(lèi)由標(biāo)題穿肄、主體年局、時(shí)間組成，分別使用char咸产、Text矢否、DateTime三種不同控件
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、執(zhí)行數(shù)據(jù)庫(kù)同步創(chuàng)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.0009_alter_user_last_name_max_length... OK
  Applying sessions.0001_initial... OK
  Applying blog.0001_initial... OK

8脑溢、創(chuàng)建超級(jí)用戶(hù)
[>>>python3 manage.py createsuperuser

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

[>>>python3 manage.py runserver
瀏覽器打開(kāi)http://127.0.0.1:8000/admin/

登錄界面

嘗試發(fā)帖僵朗，這里用到的就是models.py里配置的BlogsPost

查看管理界面赖欣，這里用到的就是admin.py里配置的BlogsPostAdmin
