djano is not a registered tag 中间件注册问题

Django自定义simple_tag时出错如下：

解决办法：

在settings里的加上红色的部分，my_tag为自定义的标签函数后面的为其地址

TEMPLATES = [

{

'BACKEND': 'django.template.backends.django.DjangoTemplates',

'DIRS': [os.path.join(BASE_DIR, 'templates')]

'APP_DIRS': True,

'OPTIONS': {

'context_processors': [

'django.template.context_processors.debug',

'django.template.context_processors.request',

'django.contrib.auth.context_processors.auth',

'django.contrib.messages.context_processors.messages',

'libraries':{

"my_tag":"app02.templates.my_tag",

]

# tid = self.request.POST.get['tempid'] [错误导不玫

tid = self.request.POST.get('tempid')

tid = self.request.POST.get['tempid']

问题如下：

解决方法：

我的python是3.7版本，所以在命令行安装支持python3以上的驱动（如果django配置的虚拟环境，请先进入虚拟环境）

pip install pyMySQL

接着在django的__init__.py输入并保存

import pymysql

pymysql.install_as_MySQLdb()

最后验证下，没有再报错。

各类模块要安装在python 目录下，可能是我设的没在虚拟环境下进行
