Running Heroku Console does not start - ruby

Question

I am trying to run Heroku console, but in the console, I get the message "Running console attached to terminal" but the console doesn't start.
In the Heroku logs, I get the error:
Error: no child processes attached.
Any help?

Answer 1

I just had a thread with Heroku support about my similar issue, here was their response, which worked for me.
So this is a bamboo app. You can either do
$ heroku console
which will tap into a running web dyno, or you can run a new console
as a one-off process with:
$ heroku run bundle exec rails console
On cedar apps you'd also be able to do
$ heroku run console
which also starts a one-off process, because the console process type
would be implied by the rails buildpack or declared in your Procfile.
It amounts to the same as the previous line.

Answer 2

I was experiencing same issues.
Try
heroku run rails console
in Rails >=3
Happy coding :)

Answer 3

Try
$ telnet rendezvous.heroku.com 5000
to test the net enabled access to that port. They mention that filtered-port issue on their guide

Answer 4

I think this is the same problem you're describing and it has an accepted answer which seemed to fix the issue for the guy that posted the question :-)
heroku run console returns 'Error connecting to process'

Answer 5

I had this problem before I'd actually pushed my code to heroku.
Once I successfully pushed and started everything (bundle, rake etc.) the console actually worked.

Answer 6

Do this and then try
In Procfile
web: bundle exec unicorn_rails -p $PORT -c config/unicorn.rb
In unicorn.rb
worker_processes 2
preload_app true
timeout 30
#resque_pid = nil
before_fork do |server, worker|
#resque_pid ||= spawn("bundle exec rake environment resque:work QUEUE=*")
end
after_fork do |server, worker|
ActiveRecord::Base.establish_connection
end
