Django:配置不正确:SECRET_KEY设置不得为空

问题:Django:配置不正确:SECRET_KEY设置不得为空

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:

(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

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 */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。

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。

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.

我有同样的错误,结果是设置或设置模块本身加载的模块或类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。

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.

在按照Daniel Greenfield的《Django两个独家报道》一书中的说明重组设置后,我遇到了同样的问题。

我通过设置解决了该问题

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project_name.settings.local")

manage.pywsgi.py

更新:

在上述解决方案中,local是我的settings文件夹中的文件名(settings / local.py),其中包含我的本地环境的设置。

解决此问题的另一种方法是将所有常用设置保留在settings / base.py中,然后为生产,登台和开发环境创建3个单独的设置文件。

您的设置文件夹如下所示:

settings/
    __init__.py
    base.py
    local.py
    prod.py
    stage.py

并将以下代码保存在 settings/__init__.py

from .base import *

env_name = os.getenv('ENV_NAME', 'local')

if env_name == 'prod':
    from .prod import *
elif env_name == 'stage':
    from .stage import *
else:
    from .local import *

I ran into the same problem after restructuring the settings as per the instructions from Daniel Greenfield’s book Two scoops of Django.

I resolved the issue by setting

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project_name.settings.local")

in manage.py and wsgi.py.

Update:

In the above solution, local is the file name (settings/local.py) inside my settings folder, which holds the settings for my local environment.

Another way to resolve this issue is to keep all your common settings inside settings/base.py and then create 3 separate settings files for your production, staging and dev environments.

Your settings folder will look like:

settings/
    __init__.py
    base.py
    local.py
    prod.py
    stage.py

and keep the following code in your settings/__init__.py

from .base import *

env_name = os.getenv('ENV_NAME', 'local')

if env_name == 'prod':
    from .prod import *
elif env_name == 'stage':
    from .stage import *
else:
    from .local import *

我有同样的错误 python manage.py runserver

对我来说,这是由于过时的已编译二进制(.pyc)文件所致。删除项目中的所有此类文件后,服​​务器再次开始运行。:)

因此,如果您无所事事地收到此错误,即不进行与Django设置有关的任何更改,那么这可能是个不错的选择。

I had the same error with python manage.py runserver.

For me, it turned out that it was because of a stale compiled binary (.pyc) file. After deleting all such files in my project, server started running again. :)

So if you get this error, out of nowhere, i.e without making any change seemingly-related to django-settings, this could be a good first measure.

删除.pyc文件

Ubuntu终端命令用于删除.pyc: find . -name "*.pyc" -exec rm -rf {} \;

我在执行python manage.py runserver时遇到了相同的错误。这是因为.pyc文件。我从项目目录中删除了.pyc文件,然后它开始工作了。

Remove .pyc files

Ubuntu terminal command for deleting .pyc : find . -name "*.pyc" -exec rm -rf {} \;

I have got same error when I did python manage.py runserver. It was because .pyc file. I deleted .pyc file from project directory then it was working.

我没有指定设置文件:

I hadn’t specified the settings file:

回答 5

它开始工作是因为在base.py上,您具有基本设置文件中所需的所有信息。您需要以下行:

SECRET_KEY = '8lu*6g0lg)9z!ba+a$ehk)xt)x%rxgb$i1&amp;022shmi1jcgihb*'

因此它可以正常工作,并且在您执行操作时from base import *,会将SECRET_KEY导入到您的development.py

在执行任何自定义设置之前,您应该始终导入基本设置。


编辑:另外,当django从程序包中导入开发时,由于您from base import *在内部定义,因此它将初始化base 内部的所有变量__init__.py

It starts working because on the base.py you have all information needed in a basic settings file. You need the line:

SECRET_KEY = '8lu*6g0lg)9z!ba+a$ehk)xt)x%rxgb$i1&amp;022shmi1jcgihb*'

So it works and when you do from base import *, it imports SECRET_KEY into your development.py.

You should always import basic settings before doing any custom settings.


EDIT: Also, when django imports development from your package, it initializes all variables inside base since you defined from base import * inside __init__.py

我认为这是环境错误,您应该尝试设置:DJANGO_SETTINGS_MODULE='correctly_settings'

如果未定义环境变量,则:SECRET_KEY = 您的开发密钥

I had the same problem with Celery. My setting.py before:

SECRET_KEY = os.environ.get('DJANGO_SECRET_KEY')

after:

SECRET_KEY = os.environ.get('DJANGO_SECRET_KEY', <YOUR developing key>)

If the environment variables are not defined then: SECRET_KEY = YOUR developing key

为了将另一个潜在的解决方案添加到组合中,我有一个settings文件夹以及一个settings.py在项目目录中。(我正在从基于环境的设置文件切换回一个文件。此后我一直在考虑。)

Python对我要导入project/settings.py还是感到困惑project/settings/__init__.py。我删除了settings目录,现在一切正常。

To throw another potential solution into the mix, I had a settings folder as well as a settings.py in my project dir. (I was switching back from environment-based settings files to one file. I have since reconsidered.)

Python was getting confused about whether I wanted to import project/settings.py or project/settings/__init__.py. I removed the settings dir and everything now works fine.

对于使用PyCharm的任何人:绿色的“运行选定的配置”按钮将产生此错误,但运行以下工作:

py manage.py runserver 127.0.0.1:8000 --settings=app_name.settings.development

要解决此问题,您需要编辑配置的环境变量。为此,请单击绿色运行按钮左侧的“选择运行/调试配置”下拉菜单,然后单击“编辑配置”。在“环境”标签下,将环境变量更改DJANGO_SETTINGS_MODULEapp_name.settings.development

For anyone using PyCharm: the green “Run selected configuration” button would produce this error, yet running the following works:

py manage.py runserver 127.0.0.1:8000 --settings=app_name.settings.development

To fix this you need to edit the configuration’s environment variables. To do this click the “Select run/debug configuration” drop-down menu to the left of the green run button and then click on “edit configuration”. Under the “environment” tab change the environment variable DJANGO_SETTINGS_MODULE to app_name.settings.development.

我的Mac OS不喜欢它没有在设置文件中找到env变量集:

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = os.environ.get('MY_SERVER_ENV_VAR_NAME')

但是将env var添加到本地Mac OS开发环境后,该错误消失了:

export MY_SERVER_ENV_VAR_NAME ='fake dev security key that is longer than 50 characters.'

就我而言,我还需要添加--settings参数:

python3 manage.py check --deploy --settings myappname.settings.production

其中production.py是一个包含设置文件夹中特定于生产的设置的文件。

My Mac OS didn’t like that it didn’t find the env variable set in the settings file:

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = os.environ.get('MY_SERVER_ENV_VAR_NAME')

but after adding the env var to my local Mac OS dev environment, the error disappeared:

export MY_SERVER_ENV_VAR_NAME ='fake dev security key that is longer than 50 characters.'

In my case, I also needed to add the --settings param:

python3 manage.py check --deploy --settings myappname.settings.production

where production.py is a file containing production specific settings inside a settings folder.

对我来说,问题是要get_text_noop反复使用LANGUAGES。

改变中

LANGUAGES = (
    ('en-gb', get_text_noop('British English')),
    ('fr', get_text_noop('French')),
)

from django.utils.translation import gettext_lazy as _

LANGUAGES = (
    ('en-gb', _('British English')),
    ('fr', _('French')),
)

在基本设置文件中解决了ImproperlyConfigured: The SECRET_KEY setting must not be empty异常。

The issue for me was calling get_text_noop in the LANGUAGES iterable.

Changing

LANGUAGES = (
    ('en-gb', get_text_noop('British English')),
    ('fr', get_text_noop('French')),
)

to

from django.utils.translation import gettext_lazy as _

LANGUAGES = (
    ('en-gb', _('British English')),
    ('fr', _('French')),
)

in the base settings file resolved the ImproperlyConfigured: The SECRET_KEY setting must not be empty exception.

答案如此之多的原因是,该异常可能与SECRET_KEY没有任何关系。可能是一个较早的exceptions正在被吞噬。使用DEBUG = True打开调试以查看真正的异常。

The reason why there are so many different answers is because the exception probably doesn’t have anything to do with the SECRET_KEY. It is probably an earlier exception that is being swallowed. Turn on debugging using DEBUG=True to see the real exception.

就我而言,经过长时间的搜索,我发现您的Django设置(设置>语言和框架> Django)中的PyCharm具有未定义的配置文件字段。您应该使该字段指向项目的设置文件。然后,您必须打开“运行/调试”设置并删除环境变量DJANGO_SETTINGS_MODULE =现有路径。

发生这种情况是因为PyCharm中的Django插件会强制配置框架。因此,没有必要配置任何os.environ.setdefault(’DJANGO_SETTINGS_MODULE’,’myapp.settings’)

In my case, after a long search I found that PyCharm in your Django settings (Settings > Languages & Frameworks > Django) had the configuration file field undefined. You should make this field point to your project’s settings file. Then, you must open the Run / Debug settings and remove the environment variable DJANGO_SETTINGS_MODULE = existing path.

This happens because the Django plugin in PyCharm forces the configuration of the framework. So there is no point in configuring any os.environ.setdefault(‘DJANGO_SETTINGS_MODULE’, ‘myapp.settings’)

导入base.py __init__.py 单独确保您不会再次重复相同的配置!。

设置环境变量 SET DJANGO_DEVELOPMENT =dev

settings/
  __init__.py
  base.py
  local.py
  production.py

__init__.py

from .base import *
if os.environ.get('DJANGO_DEVELOPMENT')=='prod':
   from .production import *
else:
   from .local import *

在已base.py配置的全局配置中。除了数据库。喜欢

SECRET_KEY, ALLOWED_HOSTS,INSTALLED_APPS,MIDDLEWARE .. etc....

local.py

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.postgresql_psycopg2',
    'NAME': 'database',
    'USER': 'postgres',
    'PASSWORD': 'password',
    'HOST': 'localhost',
    'PORT': '5432',
}
}

Import base.py in __init__.py alone. make sure you won’t repeat the same configuration again!.

set environment variable SET DJANGO_DEVELOPMENT =dev

settings/
  __init__.py
  base.py
  local.py
  production.py

In __init__.py

from .base import *
if os.environ.get('DJANGO_DEVELOPMENT')=='prod':
   from .production import *
else:
   from .local import *

In base.py configured the global configurations. except for Database. like

SECRET_KEY, ALLOWED_HOSTS,INSTALLED_APPS,MIDDLEWARE .. etc....

In local.py

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.postgresql_psycopg2',
    'NAME': 'database',
    'USER': 'postgres',
    'PASSWORD': 'password',
