Django loaddata 设置错误

Question

尝试在我的本地机器上使用 loaddata 时(win/sqlite):

python django-admin.py loaddata dumpdata.json

我收到以下错误:

raise ImportError("Settings cannot be imported, because environment variable %s is undefined." % ENVIRONMENT_VARIABLE) ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.

如果有帮助，我正在使用 djangoconfig 应用程序:

"""
Django-config settings loader.
"""

import os

CONFIG_IDENTIFIER = os.getenv("CONFIG_IDENTIFIER")
if CONFIG_IDENTIFIER is None:
    CONFIG_IDENTIFIER = 'local'

# Import defaults
from config.base import *

# Import overrides
overrides = __import__(
    "config." + CONFIG_IDENTIFIER,
    globals(),
    locals(),
    ["config"]
)

for attribute in dir(overrides):
    if attribute.isupper():
        globals()[attribute] = getattr(overrides, attribute)

项目>python manage.py loaddata dumpdata.json --settings=config.base

WARNING: Forced to run environment with LOCAL configuration.

请勿使用 django-admin.py除了设置初始项目之外的任何事情。有了项目后，请使用 manage.py相反 - 它设置对您的设置文件的引用。
