你能帮我解读这个相当深奥的错误吗？当我启动应用程序时,一切都很好,但在我尝试登录的那一刻崩溃了.
DatabaseError at /login/

我知道inet data type接受IPv4和IPv6主机和网络(但不是域名)这一事实.
回溯如下：

urls.py中的/ login / url是url(r’^ login / $’,’django.contrib.auth.views.login’,{‘template_name’：’login.html’},name =“login”) ,
环境是：
Django 1.5.1带有postgresql后端并驻留在Ubuntu 14.04机器上.特别要注意的是,在我将nginx设置为gunicorn后面的反向代理(使用端口80进行此设置)后,此错误开始出现.当我在端口8080上使用gunicorn(和女服务员,另一个纯python web服务器)时,事情很有效.
在/ etc / nginx的/网站可用/ myproject的：
server {
listen 80;
server_name example.cloudapp.net;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {

这是怎么回事？
注意：如果您需要,请向我询问更多信息,例如：我的gunicorn.conf和nginx.conf看起来如何,安装包或者你需要db相关的东西.请问！
解决方法:
您没有转发代理IP.这是我在nginx配置中设置的转发标头集：
location / {
proxy_set_header Host $http_host;
proxy_set_header User-Agent $http_user_agent;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass ......;
}
nginx docs中的更多选项 – http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_set_header
然后在Django你可以这样做：
user_ip = request.META['HTTP_X_REAL_IP`] or request.META['REMOTE_ADDR']
请注意,当使用带有SSL的Django时,X-Forwarded-Proto是必需的,在这种情况下,您还需要稍微配置Django：
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
