I have recently taken the habit of checking on Rails forum from time to time whether there are unanswered questions I can help with. The best way to see a problem in its context is to recreate it and I was amazed by how easy it is to set up a rails site and debug e.g a routing problem.
> rails railsforum_help_routing > createdb railsforum_help_routing_development (edit database.yml to set user and possibly database type) > script/generate model Trip > script/generate controller Trip (edit routes.rb, in this case)
Naturally the fact that all this takes about 5 minutes greatly leverages lending a hand to a fellow developer. Now that’s what I call agile!
