本文介绍了Django:不正确配置:SECRET_KEY设置不能为空的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

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,..)。不能成功。当我尝试运行 ./ manage.py runserver 我收到以下错误:

 (cb)clime @ den / srv / www / cb $ ./manage.py runserver 
不正确的配置: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 
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):

 (cb)clime @ den / srv / www / cb / cb / settings $ cat base.py

如果我从基地添加导入* / srv / www / cb / cb / settings / __ init __。py (否则为空),它神奇地开始工作,我不明白为什么任何人都可以向我解释这里发生了什么?它必须是一些python模块魔术。



编辑:如果我从base.py

中删除这一行,所有内容都会开始工作

  django.template.loader.add_to_builtins('web.templatetags.cb_tags')

如果我从web.templatetags.cb_tags中删除这一行,它也开始工作:

  from endless_pagination.templatetags import endless 

我猜是因为在结束,它导致从django.conf导入设置
PER_PAGE = getattr(设置,'ENDLESS_PAGINATION_PER_PAGE',10)中的

 

所以它创建了一些奇怪的循环内容和游戏。

解决方案

我有同样的错误,原来是由设置加载的设置和设置模块本身之间的循环依赖。在我的情况下,这是一个中间件类,它在本身尝试加载设置的设置中命名。


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:

    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "cb.settings.development")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

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 something 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.
