https redirect for rails app behind proxy?

Question

server declaration in my nginx.conf:

    listen       1.2.3.4:443 ssl;
    root /var/www/myapp/current/public;
    ssl on;
    ssl_certificate /etc/nginx-cer         


        

Answer 1

You can pass :protocol => "https", to redirect_to.

You can set this as a default by adding the following to application.rb

Rails.application.routes.default_url_options[:protocol]= 'https'

Answer 2

You need to add the following line:

proxy_set_header X-Forwarded-Proto https;

as in

location / {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_set_header X-Forwarded-Proto https;
      proxy_redirect off;

      if (!-f $request_filename) {
        proxy_pass http://upstreamy;
        break;
      }
 }
