os.environ.setdefault('DJANGO_SETTINGS_MODULE') 不起作用

Question

我正在尝试运行一个使用 Django 模型访问数据库的独立脚本。

该脚本非常简单，请参见下文：

import sys
from manager.models import Playlist
from manager.utils import clean_up_playlist, add_record_to_playlist

def main(playlist_id, username):
    playlist = Playlist.objects.get(playlists=playlist_id)
    # the script does other stuff


if __name__ == "__main__":
    playlist_id = sys.argv[1]
    username = sys.argv[2]
    import os
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'SpotifyPlaylistManager.settings')
    import django
    django.setup()
    main(playlist_id, username)

该脚本位于 Django 文件夹的顶部文件夹中

SpotifyPlaylistManager/
|-SpotifyPlaylistManager/
  |-settings.py
|-venv
|-manage.py
|-my_script.py

出于某种原因，如果我尝试使用下面的命令运行它，则会收到错误我

raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

需要启动的实际命令

source /home/nicola/PycharmProjects/SpotifyPlaylistManager/venv/bin/activate && python /home/nicola/PycharmProjects/SpotifyPlaylistManager/scheduler.py 6tIMeXF1Q9bB7KDywBhG2P nicoc && deactivate

我找不到问题

将 Django include 移动到主要工作中

if __name__ == "__main__":
    playlist_id = sys.argv[1]
    username = sys.argv[2]
    import os
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'SpotifyPlaylistManager.settings')
    import django
    django.setup()
    from manager.models import Playlist
    from manager.utils import clean_up_playlist, add_record_to_playlist

    main(playlist_id, username)
