nginx - Make rails url_helpers use https in production -

i use rails url_helpers build resources urls in app. example of url in development http://localhost:3000/resource/1, generated resource_url(resource) url_helper.

i use nginx in production proxy_pass requests rails app. nginx listens on port 433 https , redirects rails app on port 5000 http:

server {   listen 443 ssl;   server_name     api.staging.zup.me;    ssl_certificate /etc/ssl/certs/cert.crt;   ssl_certificate_key /etc/ssl/certs/cert.key;    location / {     proxy_redirect off;     proxy_set_header x-real-ip $remote_addr;     proxy_set_header host $host:$server_port;     proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;     proxy_pass      http://localhost:5000;   } } 

because request rails app receives nginx proxy http, generating urls like, http://example.com/resource/1, in production want urls use https, example, https://example.com/resource/1.

what best way make rails generate urls https protocol in production?

you can use redirect in nginx , never touch rails app enable https:

server {   listen 80 default_server deferred;   server_name myserver.domain;    return 301 https://$server_name$request_uri;  # enforce https }  # https server server {   listen 443;   server_name myserver.domain;   ssl on;   ssl_certificate /etc/nginx/ssl/myserver.domain.crt;   ssl_certificate_key /etc/nginx/ssl/myserver.domain.key;    root /srv/www/myserver;   ... } 

not sure if it's best way, becuase don't have rails app, nginx.
