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()
      .
      .
      .
            File "/Library/Python/2.7/site-packages/django/conf/__init__.py", line 115, in __init__
        raise ImproperlyConfigured("The SECRET_KEY setting must not be empty.")
    django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.

这是我的settings.py

""" Django settings for dbe project.  """

    execute_from_command_line(sys.argv)

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

SECRET_KEY复制到您的设置文件中。

答案 1 :(得分:3)

settings.py中的

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$HOME/.bashrc$HOME/.zshrc/etc/bashrc/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。
