Troubleshooting my Heroku launch

So I am having trouble launching my Heroku Rails app giving me this. I don't have a procfile and I think that may be part of it. Here is my repository: https://github.com/cody-mum1228/toy_app

This is local.

Thanks in advance dudes!

You're going through Hartl's Rails tutorial, yes? Did you deploy the "Hello World!" app ok, or did it give you the same issues?

You don't necessarily need a Procfile for Rails deployment. Heroku will use the default Rails server if it's missing. From the logs it looked like it failed to find ruby2.3 (the brand new version), which you specified in the Gemfile. Heroku defaults to 2.2, iirc, I'd suggest removing the ruby line from the Gemfile (Or, better yet use the Gemfile Hartl provides if you're using his tutorial), re running bundle install/update, and trying it again.

I went through hell to change my Ruby to version 2.2, but it fixed it. Thanks for the bit advice dude.

Hi Cody,

I only know a very small amount about Ruby or Rails. However, I've deployed to Heroku before with node. It's almost seemless, except for the enviornment variables, so I checked out the quickstart for Rails, and found that procfile you were talking about in the quickstart repo. It only had one line:

web: bundle exec puma -C config/puma.rb

So I went to the config/puma.rb file it was pointing to and found this:

workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['MAX_THREADS'] || 5)
threads threads_count, threads_count

preload_app!

rackup      DefaultRackup
port        ENV['PORT']     || 3000
environment ENV['RACK_ENV'] || 'development'

on_worker_boot do
  # Worker specific setup for Rails 4.1+
  # See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
  ActiveRecord::Base.establish_connection
end

There are those enviornment variables I was talking about. So I don't know how you want to implement it or how, because I'm not a Ruby on Rails guy, but you have to point the server to those PORT, RACK_ENV, etc. variables. I hope that helps. Happy coding!

Nicolas
