我正在尝试设置多个包含一些基本设置的设置文件(开发、生产……).虽然不能成功.当我尝试运行 ./manage.py runserver 我收到以下错误:
I am trying to set up multiple setting files (development, production, ..) that include some base settings. Cannot succeed though. When I try to run ./manage.py runserver I am getting the following error:
(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

如果我将 from base import * 添加到 /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里发生了什么?这一定是某种 python 模块的魔法.
If I add from base import * into /srv/www/cb/cb/settings/__init__.py (which is otherwise empty), it magically starts to work but I don't understand why. Anyone could explain to me what's going on here? It must be some python module magic.
如果我从 base.py 中删除这一行，一切都会开始工作
Everything also starts to work if I remove this line from base.py
django.template.loader.add_to_builtins('web.templatetags.cb_tags')
如果我从 web.templatetags.cb_tags 中删除这一行，它也会开始工作:
If I remove this line from web.templatetags.cb_tags, it also starts to work:
from endless_pagination.templatetags import endless
我猜是因为，最终，它导致了
I guess it is because, in the end, it leads to
from django.conf import settings
PER_PAGE = getattr(settings, 'ENDLESS_PAGINATION_PER_PAGE', 10)
所以它创造了一些奇怪的圆形东西，游戏结束了.
So it creates some weird circular stuff and game over.
我遇到了同样的错误，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.在我的例子中，它是一个在设置中命名的中间件类，它本身试图加载设置.
I had the same error and it turned out to be a circular dependency between a module or class loaded by the settings and the settings module itself. In my case it was a middleware class which was named in the settings which itself tried to load the settings.
