模块导入应用settings的字符串

Posted 2020-10-30 Stay-J

看django源码，感觉他的settings好高大上然后自己试试

以上是文件目录

email.py中代码

class Email:
    def send(self):
        print(\'发送email\')

　　

Msg.py有类似的代码

class Msg:
    def send(self):
        print(\'msg\')

　　

Phone.py

class Phone:
    def send(self):
        print(\'phone\')

　　

settings.py

NOTIFY_LIST = [
    \'s123.email.Email\',
    \'s123.Msg.Msg\',
    \'s123.Phone.Phone\',
]

　　

from setting import *
import importlib


def send_xxx():
    for i in NOTIFY_LIST:
        model_name, class_name = i.rsplit(\'.\', maxsplit=1)
        model = importlib.import_module(model_name)
        class_name = getattr(model, class_name)
        obj = class_name()
        obj.send()

__init__.py

 

import s123

if __name__ == \'__main__\':
    s123.send_xxx()

app01.py
