If there's one thing I do a lot of is building Rails applications for deployment to Heroku. It's also something that my colleagues at Kyan do. Keeping up to date with the best practices and Heroku's own recommended best practices is tough - not to mention configuring your application for a seamless asset pipeline deploy.
So I set about to change that with a Rails template that when applied to a vanilla Rails application means that given a few edge cases it's almost 100% guaranteed (I'll give you your money back!) to deploy and run successfully.
My template is both Rails 3 and Rails 4 compatible and determines which version you have installed when it is invoked by simply doing
rails new -m https://github.com/johnbeynon/heroku-rails-template
You can see here the full details of what the template does. Remembering a URL like that isn't particular easy and if it's not easy to remember you'll forget to use it, so I also whipped up a quick plugin for the Heroku CLI which you can install via
heroku plugins:install https://github.com/johnbeynon/heroku-rails-new.git
Once installed you will be able to do:
heroku new:rails <appname>
and voila, you will have a Rails 3/4 application that's good for deployment to Heroku.
