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。

脚本非常简单，请参阅以下内容：

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)

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，如果我尝试用下面的命令运行它，我会得到错误

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.

我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移动到主要工作的中

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)
