錯誤信息，詢問密鑰，但密鑰已經插入

Question

運行我的後端Django的時，我不斷收到一個錯誤。

這裏是回溯：

django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty. 

這裏是我的網址：

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}), 
] 

還有什麼，我可以試試。我知道最近的Django的版本有網址的問題，但我不是如何解決這些問題正是熟悉。

這裏是我的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) 

而且，這裏是我的setting.py文件（未插入密鑰）：

Answer 1

您的問題是，您要導入的settings而不是在你的urls.pyhttps://docs.djangoproject.com/en/1.10/topics/settings/#using-settings-in-python-code

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

使用

應該是

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