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:菜鸟

我很想正确设置DJANGO_SETTINGS_MODULE,以便最终将我的模型导入脚本中。我在项目中使用virtualenv

这是我当前的错误:

ModuleNotFoundError: No module named 'dashex'

以及相应的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

我首先使用了here发布的settings.configure()解决方案。但是,此解决方案引发了this错误...因此,我希望DJANGO_SETTINGS_MODULE能够解决问题。

根据文档(docu),我必须使用Django-admin来设置DJANGO_SETTINGS_MODULE

我尝试过的事情:

  • 在Windows的命令提示符中执行
    $ set DJANGO_SETTINGS_MODULE=dashex.settings,什么也没发生。

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

  • 在我项目的$ django-admin set DJANGO_SETTINGS_MODULE=dashex.settings根目录中执行
    manage.py会引发错误no module named dashex

  • @Casper的
  • This答案建议执行上述操作,但是如何处理:
    C:\temp\testproject> set DJANGO_SETTINGS_MODULE=testproject.settings吗?

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

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

  • 已执行
    $ py manage.py runserver --settings=dashex.settings,它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。

工作解决方案:

import sys
sys.path.insert(0, r"C:\Users\Jonas\Desktop\Dashex")
import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'Dashex.settings'
import django
django.setup()
from Dashboard.models import AccountInformation
[...]

答案 0 :(得分:2)

django-admin和manage.py不用于设置环境变量,因此问题中的命令,例如django-admin set DJANGO_SETTINGS_MODULE=dashex.settings毫无意义。

在Windows上,可以在运行脚本之前在命令提示符下运行set DJANGO_SETTINGS_MODULE=dashex.settings。您说不想使用外壳程序,因此在脚本中设置环境变量可能会更容易。

import os
import sys
os.environ['DJANGO_SETTINGS_MODULE'] = 'dashex.settings'

# Since feeder.py is in Dashboard_app, you need to add the parent directory
# to the python path so that dashex can be imported
# (without this you'll get the 'no module named dashex' error)
sys.path.append('..')

import django
django.setup()

# Now you can import models
