我正在尝试设置包括某些基本设置的多个设置文件(开发,生产等)。虽然无法成功。当我尝试运行./manage.py runserver时,出现以下错误:
./manage.py runserver
(cb)clime@den /srv/www/cb $ ./manage.py runserver ImproperlyConfigured: The SECRET_KEY setting must not be empty.
这是我的设置模块:
(cb)clime@den /srv/www/cb/cb/settings $ ll total 24 -rw-rw-r--. 1 clime clime 8230 Oct 2 02:56 base.py -rw-rw-r--. 1 clime clime 489 Oct 2 03:09 development.py -rw-rw-r--. 1 clime clime 24 Oct 2 02:34 __init__.py -rw-rw-r--. 1 clime clime 471 Oct 2 02:51 production.py
基本设置(包含SECRET_KEY):

设置文件之一:
(cb)clime@den /srv/www/cb/cb/settings $ cat development.py from base import * DEBUG = True TEMPLATE_DEBUG = True ALLOWED_HOSTS = ['127.0.0.1', '31.31.78.149'] DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'cwu', 'USER': 'clime', 'PASSWORD': '', 'HOST': '', 'PORT': '', } } MEDIA_ROOT = '/srv/www/cb/media/' STATIC_ROOT = '/srv/www/cb/static/' TEMPLATE_DIRS = ( '/srv/www/cb/web/templates', '/srv/www/cb/templates', )
代码在manage.py:
manage.py
(cb)clime@den /srv/www/cb $ cat manage.py #!/usr/bin/env python import os import sys if __name__ == "__main__": os.environ.setdefault("DJANGO_SETTINGS_MODULE", "cb.settings.development") from django.core.management import execute_from_command_line execute_from_command_line(sys.argv)
如果添加from base import *到/srv/www/cb/cb/settings/__init__.py(否则为空),它会神奇地开始工作,但我不明白为什么。任何人都可以向我解释这是怎么回事?它一定是一些python模块魔术。
from base import *
/srv/www/cb/cb/settings/__init__.py
编辑: 如果我从base.py中删除此行,一切也将开始工作
django.template.loader.add_to_builtins('web.templatetags.cb_tags')
如果我从web.templatetags.cb_tags中删除此行,它也将开始工作:
from endless_pagination.templatetags import endless
我想这是因为最终导致
from django.conf import settings PER_PAGE = getattr(settings, 'ENDLESS_PAGINATION_PER_PAGE', 10)
因此,它会产生一些怪异的循环内容并结束游戏。
我有同样的错误,结果是设置加载的模块或类与设置模块本身之间存在循环依赖关系。在我的情况下,这是一个中间件类,该类在设置中被命名,该类本身试图加载设置。
