Django loaddata设置错误

Question

尝试在我的本地计算机上使用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.

我正在使用djangoconfig应用程序,如果这有助于:

"""
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)

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

django-admin.py除了设置初始项目之外,不要使用任何其他内容.有了项目后,请manage.py改用 - 它会设置对您的设置文件的引用.
