# Deploying a Sinatra app to Heroku

## Database
The location of the database Heroku provides can be found in the environment
variable DATABASE_URL. Check the configure-block of toodeloo.rb for an example
on how to use this.

## Server
Heroku is serving your apps with thin, with means you have all your thin goodness available,
such as EventMachine.

If only one of the text fields are filled in the params will look like this:

  {"foo" => "bar"}

While it looks like this if both are filled in:

  {"foo" => ["bar", "baz"]}

And really, in the first case it *should* be:

1. I copy http://github.com/ichverstehe/foo/commit/17a5a5d55cb28ea1440be1f704497a588694aab3
2. In jello.rb L17 pasteboard.gets sets @current = http://github.com/ichverstehe/foo/commit/17a5a5d55cb28ea1440be1f704497a588694aab3
3. I have  shortener  enabled, so after all moulds have been ran, the pasteboard now contains http://tr.im/f7v7?github
4. The loop is repeated, and at jello.rb L17 pasteboard.gets sets @last to @current, which is still the original github-url, and thus pasteboard.gets (which is http://tr.im/..) != @last and the moulds are walked through once more.

On the other hand, if Pasteboard#puts updates @current (which is logically correct, as the current pasteboard *is* whatever #puts sets it to) each copy will only get one time through the moulds.

Doesn't matter much, except, for my Growl mould, where I really prefer only getting one notification :)
