ModuleNotFoundError：没有名为Foo的模块-如何将模型导入Django应用程序的脚本中？

我的Django技能水平：noob。

我很想DJANGO_SETTINGS_MODULE正确设置最终将模型导入脚本中。我将avirtualenv用于我的项目。

这是我目前的错误：

ModuleNotFoundError: No module named 'dashex'

和相应的feeder.py脚本：

import os
import sys
os.environ['DJANGO_SETTINGS_MODULE'] = 'dashex.settings'
sys.path.append('os.path.dirname(os.path.dirname(os.path.abspath(__file__)))')
import django
django.setup()
import zmq
import time
from time import sleep
import uuid
from Dashboard_app.models import AccountInformation
[...]

背景：

我首先使用这里settings.configure()发布的解决方案。但是，此解决方案引发了此错误...因此，我希望可以做到这一点。DJANGO_SETTINGS_MODULE

根据文档（docu），我必须使用Django-adminset DJANGO_SETTINGS_MODULE。

我尝试过的

• 
  $ set DJANGO_SETTINGS_MODULE=dashex.settings在Windows上的命令提示符下执行，什么都没有发生。
  

• 执行
  $ py manage.py set DJANGO_SETTINGS_MODULE=dashex.settings将引发错误unknown command set

• 
  $ django-admin set DJANGO_SETTINGS_MODULE=dashex.settings在manage.py我的项目的根目录中执行会引发错误no module named dashex。

• 这从@Casper答案建议做上面提到的，但如何处理这个问题：
  C:\temp\testproject> set DJANGO_SETTINGS_MODULE=testproject.settings？

• @Max的此解决方案建议将其附加export DJANGO_SETTINGS_MODULE=<django_project>.settings到我的虚拟环境中。这是什么意思，该怎么做？

• 执行
  $ django-admin runserver --settings=dashex.settings也会引发错误no module named dashex。

• 执行后
  $ py manage.py runserver --settings=dashex.settings，将以正确的设置启动服务器。但是最初提到的错误仍然存​​在。

我的项目：

Settings.py：

import os.path
import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))


# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/2.2/howto/static-files/


STATIC_ROOT = ''
STATIC_URL = '/static/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')]

import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'Dashex.settings'
import django
django.setup()
