Tested on: Datatable 1.8.2, Rails 3.1.3
This example uses Coffeescript and Haml (you should too :-) )

The following is an example of Datatables server-side processing of a table 
which displays a user's song list including the songs' artist names.  In 
Rails, Song and Artist are ActiveRecord models in a one artist-many song relat.

Migrating a Rails project from MySQL to PostgreSQL

This brief guide is written from my own experience with migrating a large (~5GB) MySQL database to PostgreSQL for a Rails project.

No warranties, guarantees, support etc. Use at your own risk and, as always, ENSURE YOU MAKE BACKUPS FIRST!

I chose [pgloader][1] because it's extremely fast. YMMV.

1. Replace mysql2 gem with pg in Gemfile.
2. Update config/database.yml for PostgreSQL. I used [Rails' template][2] as a starting point.
