Django 2.2之集成SimpleUI 3.8及KeyErrors: "simpletags"异常解决

#1. 环境

• Windows 10
• Python 3.6.1
• VirtualENV
• Django 2.2
• SimpleUI 3.8
• Eclipse 4.6.3 + PyDev 5.7
• 内网环境
• 官方上手指南

#2. Eclipse新建Pydev Django Project

F:\ECLIPSE463\SIMPLEUIOFFICETEST
│  .project
│  .pydevproject
│  db.sqlite3
│  manage.py
│
└─SimpleUIOfficeTest
    │  settings.py
    │  urls.py
    │  wsgi.py
    │  __init__.py
    │
    └─__pycache__
            settings.cpython-36.pyc
            urls.cpython-36.pyc
            wsgi.cpython-36.pyc
            __init__.cpython-36.pyc

#3. 设置项目的settings.py文件加入以下2句:

INSTALLED_APPS = [
    'simpleui',
	..........
]
SIMPLEUI_STATIC_OFFLINE = True  #能联网的可忽略

#4. 创建默认数据库文件

#5. 创建超级管理员

(django22) F:\eclipse463\SimpleUIOfficeTest>python manage.py createsuperuser
Username (leave blank to use 'admin'): admin
Email address: [email protected]
Password:
Password (again):
Superuser created successfully.

#6. 启动项目并查看

python manage.py runserver
#浏览器打开
http://127.0.0.1:8000/admin/

#7. 异常提示

KeyErrors: "simpletags"

#8. 原因及解决

报错来源： 是simpleui安装路径下\site-packages\simpleui\templates\admin的login.html引入{% load i18n static simpletags %}, 但是找不到simpletags所致。
原因：是安装simpleui时, 不知何故源码包里明明存在templatetags文件夹, 但是安装完成后不见了。
解决：直接把源码包里的templatetags文件夹拷贝到\site-packages\simpleui\下面即可。
