Question

在为Django运行后端时，我一直收到错误。

这是追溯：

    raise ImproperlyConfigured("The SECRET_KEY setting must not be empty.")
django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.

以下是我的网址：

from django.conf.urls import include, url
from django.contrib import admin
from django.views.static import serve
import settings

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^recipes/', include('apps.recipes.urls')),
    url(r'^media/(?P<path>.*)$', serve, {'document_root': settings.MEDIA_ROOT}),
]

还有什么我可以尝试的吗？我知道Django的最新版本存在网址问题，但我并不完全熟悉如何修复它们。

这是我的manage.py文件：

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "recipe_organizer.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

此外，这是我的setting.py文件（未插入密钥）：

您的问题是您导入settings而不是django.conf.settings https://docs.djangoproject.com/en/1.10/topics/settings/#using-settings-in-python-code

中使用urls.py

from django.conf.urls import include, url
from django.contrib import admin
from django.views.static import serve
import settings  # <- here

应该是

from django.conf.urls import include, url
from django.contrib import admin
from django.views.static import serve
from django.conf import settings

请求密钥但是已插入密钥时出错
