How to get into Rails Console

Support
1

I recently updated Discourse after being out of date for 6-7 months. I noticed ./launcher ssh app doesn’t work anymore and if I use enter app then rails c, I get an error.

root@rdu-forums-01-app:/var/www/discourse/plugins/categorywatcher# rails c

^C/var/www/discourse/vendor/bundle/ruby/2.4.0/gems/activesupport-5.1.4/lib/active_support/dependencies.rb:292:in `require': Interrupt
        from /var/www/discourse/vendor/bundle/ruby/2.4.0/gems/activesupport-5.1.4/lib/active_support/dependencies.rb:292:in `block in require'

        from /var/www/discourse/vendor/bundle/ruby/2.4.0/gems/activesupport-5.1.4/lib/active_support/dependencies.rb:292:in `require'

Has anyone seen this?

First of all, could you please wrap your console output in a code block instead of a quote block? There’s Markdown syntax being interpreted in there.

Secondly, no, I’m not seeing it.

It did take me like a minute after hitting enter at “rails c” before the pry prompt came up. Maybe wait longer?

Opening the rails console can take a while, depending on the work load of your application and server. This isn’t really app specific, you can see that with Gitlab too.

The exception you are seeing originates from Crtl+C (^C before the stacktrace), interpreted as interrupt signal by the current running process.

Just wait a little longer as @notriddle suggested :slight_smile:

Kind regards,
Michael

Working fine here, but does take a number of seconds (counted around 10 seconds) for the prompt:

root@discourse1-app:/shared/neo/bin# rails c

[1] pry(main)>
