问题描述
我正在尝试设置包含一些基本设置的多个设置文件(开发、生产、..).虽然不能成功.当我尝试运行 ./manage.py runserver
时,出现以下错误:
(cb)clime@den/srv/www/cb $ ./manage.py runserverImproperlyConfigured:SECRET_KEY 设置不能为空.
这是我的设置模块:
(cb)clime@den/srv/www/cb/cb/settings $ ll共 24 个-rw-rw-r--.1 气候气候 8230 Oct 2 02:56 base.py-rw-rw-r--.1 气候气候 489 Oct 2 03:09 development.py-rw-rw-r--.1 气候气候 24 Oct 2 02:34 __init__.py-rw-rw-r--.1 气候气候 471 Oct 2 02:51 production.py

如果我将 from base import *
添加到 /srv/www/cb/cb/settings/__init__.py
(否则为空),它神奇地开始工作,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?这一定是一些python模块魔术.
如果我从 base.py 中删除这一行,一切都会开始工作
django.template.loader.add_to_builtins('web.templatetags.cb_tags')
如果我从 web.templatetags.cb_tags 中删除这一行,它也会开始工作:
from 无尽分页.templatetags 导入无尽
我猜是因为,最终导致了
from django.conf 导入设置PER_PAGE = getattr(设置,'ENDLESS_PAGINATION_PER_PAGE',10)
因此它创建了一些奇怪的循环内容并结束游戏.
解决方案
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 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:

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.
EDIT: Everything also starts to work if I remove this line from base.py
django.template.loader.add_to_builtins('web.templatetags.cb_tags')
If I remove this line from web.templatetags.cb_tags, it also starts to work:
from endless_pagination.templatetags import endless
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)
So it creates some weird circular stuff and game over.
解决方案
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.
