无法在Python / Django中导入变量

我的django项目中的相关文件夹就在这里。

-config(文件夹)
- 设置(文件夹)
---common.py
--- production.py

-core(文件夹)
- 管理(文件夹)
---命令(文件夹)
--- my_command.py

我有一个名为MYVAR的变量。如果我将它放在common.py中并将其导入到my_command.py中,就可以了。它可以正常工作。

from django.conf import settings

class Command(BaseCommand):
    def handle(self, *args, **options):
      test = settings.MYVAR

但是如果我将MYVAR放在production.py并运行相同的代码片段,它就无法找到变量。

这里发生了什么? common.py和production.py位于同一文件夹(设置)中。为什么不从production.py导入?

import os, sys, inspect
 # realpath() will make your script run, even if you symlink it :)
 cmd_folder = os.path.realpath(os.path.abspath(os.path.split(inspect.getfile( inspect.currentframe() ))[0]))
 if cmd_folder not in sys.path:
     sys.path.insert(0, cmd_folder)

 # use this if you want to include modules from a subfolder
 cmd_subfolder = os.path.realpath(os.path.abspath(os.path.join(os.path.split(inspect.getfile( inspect.currentframe() ))[0],"subfolder")))
 if cmd_subfolder not in sys.path:
     sys.path.insert(0, cmd_subfolder)

 # Info:
 # cmd_folder = os.path.dirname(os.path.abspath(__file__)) # DO NOT USE __file__ !!!
 # __file__ fails if script is called in different ways on Windows
 # __file__ fails if someone does os.chdir() before
 # sys.argv[0] also fails because it doesn't not always contains the path
