I think the ActiveRecord Associations Guide I wrote may actually be finished.

  • Dynamic Rails Error Help - Making the default validation messages more useful with a bit of javascript.

  • Exceptional - This online error-tracker for Rails apps is now in open beta.

  • Is Your Rails Application Safe? - If you're inadvertently allowing mass assignment, probably not.

  • MysqlTableSyncer - Command-line tool to synch up two MySQL tables.

  • turl - My contribution to a little scripting fest on Twitter yesterday. If you have FF3 + Ubiquity, you can use "turl <userid>" to go straight to a Twitter user's web site.
