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

问题描述

我的 Django 技能水平：noob。

我在设置DJANGO_SETTINGS_MODULE正确以最终在脚本中导入我的模型时发疯了。我将 avirtualenv用于我的项目。

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：

我首先使用了此处settings.configure()发布的解决方案。但是，这个解决方案引发了这个错误......所以我希望能做到这一点。DJANGO_SETTINGS_MODULE

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

我试过的：

我的项目：

设置.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')]


# Quick-start development settings - unsuitable for production

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = ''

DEBUG = True

ALLOWED_HOSTS = ["127.0.0.1", "locahost"]

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
[...]

解决方案

django-admin 和 manage.py 不用于设置环境变量，因此您问题中的命令django-admin set DJANGO_SETTINGS_MODULE=dashex.settings没有意义。

在 Windows 上，您可以set DJANGO_SETTINGS_MODULE=dashex.settings在运行脚本之前在命令提示符下运行。您说您不想使用 shell，因此在脚本中设置环境变量可能更容易。

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
