django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty
提问by Ashish Patil
I created a new project in django and pasted some files from another project. Whenever I try to run the server, I get the following error message:
我在 django 中创建了一个新项目并粘贴了另一个项目中的一些文件。每当我尝试运行服务器时，都会收到以下错误消息：
Traceback (most recent call last):
File "manage.py", line 10, in <module>
execute_from_command_line(sys.argv)
File "/Library/Python/2.7/site-packages/django/core/management/__init__.py", line 385, in execute_from_command_line
utility.execute()

Here's my settings.py

Just like the error says, you have no SECRET_KEYdefined. You need to add one to your settings.py.
就像错误所说，你没有SECRET_KEY定义。您需要在settings.py 中添加一个。
Django will refuse to start if
SECRET_KEYis not set.
如果
SECRET_KEY未设置，Django 将拒绝启动。
You can read more about this setting in the docs.
您可以在文档中阅读有关此设置的更多信息。
The SECRET_KEYcan be just about anything...but if you want to use Django to generate one, you can do the following from the python shell:
该SECRET_KEY可以做出点事来......但如果你想使用Django生成一个，你可以从Python壳以下：
>>> from django.utils.crypto import get_random_string
>>> chars = 'abcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*(-_=+)'
>>> SECRET_KEY = get_random_string(50, chars)
>>> print SECRET_KEY
Copy the SECRET_KEYto your settings file.
将其复制SECRET_KEY到您的设置文件。

SECRET_KEYvariable in settings.py should be kept secret
SECRET_KEYsettings.py 中的变量应该保密
You can place the string secret key generated with the get_random_stringfunction above (as said @rnevius ) in settings.py but use a function that get the variable.
您可以将使用上述get_random_string函数生成的字符串密钥（如@rnevius 所述）放在 settings.py 中，但使用获取变量的函数。
This means, that for security reasons, it is better to hide the content of SECRET_KEY variable.
这意味着，出于安全原因，最好隐藏 SECRET_KEY 变量的内容。
You can define an environment variable as follow:
您可以按如下方式定义环境变量：
In your $HOME/.bashrcor $HOME/.zshrcor /etc/bashrcor /etc/bash.bashrcaccording to your unix operating system and terminal manager that you use:
在您$HOME/.bashrc或$HOME/.zshrc或/etc/bashrc或/etc/bash.bashrc根据您使用的 unix 操作系统和终端管理器中：
export SECRET_KEY='value_of_the_secret_key_generated_by_get_random_string_function'
you can look something like this:
你可以看起来像这样：
export SECRET_KEY='lmrffsgfhrilklg-za7#57vi!zr)ps8)2anyona25###dl)s-#s=7=vn_'
And in the settings.py you can add this:
在 settings.py 中，您可以添加以下内容：
import os
from django.core.exceptions import ImproperlyConfigured
def get_env_variable(var_name):
try:
return os.environ[var_name]
except KeyError:
error_msg = "Set the %s environment variable" % var_name
raise ImproperlyConfigured(error_msg)
SECRET_KEY = get_env_variable('SECRET_KEY')
The function get_env_variable tries to get the variable var_name from the environment, and if it doesn't find it, it raises an ImproperlyConfigured error. Using it in this way, when you try to run your app and the SECRET_KEY variable is not found, you will be able to see a message indicating why our project fails.
函数 get_env_variable 尝试从环境中获取变量 var_name，如果找不到，则会引发 ImproperlyConfigured 错误。以这种方式使用它，当您尝试运行您的应用程序并且未找到 SECRET_KEY 变量时，您将能够看到一条消息，表明我们的项目失败的原因。
Also you can protect the secret content variables of the project in this way.
您也可以通过这种方式保护项目的秘密内容变量。
