Pry on the production server - how can I make it work there?

I can debug an app locally with binding.pry just fine. But I need to that on the remote server (webiste) as well, because locally I don't have any error but on production I do. So put binding.pry in the source file on the server and when I made a post request to the website, I didn't return any response and even when I ran rails console on the server didn't change anything and there was no output in rails console.

It's a dev server, so it's visible in the internet but it's a developer server, although for rails it's production because RAIL_ENV is equal to production. I really need to debug it the way I can do locally using pry. How can I do it?

update:

# bundle exec pry-remote

I assume your production app is run by some kind of daemonized application server, such as Puma or Unicorn.

In this setup, pry-remote can help.

  1. add it to your Gemfile
  2. use binding.remote_pry instead of binding.pry
  3. execute bundle exec pry-remote on your server

You'll get a pry shell as soon as the breakpoint has been hit.
