I'm pushing changes to Heroku and I get ... rake aborted! could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?

Putting aside Coffescript for the moment, one thing that I've been wondering is how to properly use the model-specific .js files in the asset pipeline. For example, when working with my User model, I may have some code that I want to have run when the document is ready. Let's say I put that in $(document).ready(function() {...}); in the users.js file generated by Rails 3.1. The next day, I'm
