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>

这是我的settings.py

有任何帮助吗?谢谢!
答案 0 :(得分:19)
就像错误一样,您没有定义SECRET_KEY
。您需要在 settings.py 中添加一个。
如果未设置
SECRET_KEY
,Django将拒绝启动。
您可以详细了解此设置in the docs。
SECRET_KEY
可以是任何东西......但是如果你想使用Django生成一个,你可以从python shell中执行以下操作:
>>> from django.utils.crypto import get_random_string
>>> chars = 'abcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*(-_=+)'
>>> SECRET_KEY = get_random_string(50, chars)
>>> print SECRET_KEY
将SECRET_KEY
复制到您的设置文件中。
答案 1 :(得分:3)
SECRET_KEY
变量应保密:
您可以在settings.py中放置使用get_random_string
函数生成的字符串密钥(如所述@rnevius),但使用获取变量的函数。
这意味着,出于安全原因,最好隐藏SECRET_KEY变量的内容。
您可以按如下方式定义环境变量:
根据您使用的unix操作系统和终端管理器,在$HOME/.bashrc
或$HOME/.zshrc
或/etc/bashrc
或/etc/bash.bashrc
中:
export SECRET_KEY='value_of_the_secret_key_generated_by_get_random_string_function'
你可以看起来像这样:
export SECRET_KEY='lmrffsgfhrilklg-za7#57vi!zr)ps8)2anyona25###dl)s-#s=7=vn_'
在settings.py中你可以添加:
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')
函数get_env_variable尝试从环境中获取变量var_name,如果找不到它,则会引发一个ImproperlyConfigured错误。以这种方式使用它,当您尝试运行应用程序并且找不到SECRET_KEY变量时,您将能够看到一条消息,指出我们的项目失败的原因。
此外,您可以通过这种方式保护项目的秘密内容变量。
