In setting up a new Rails app recently I was told that it needed to be served under the sub-URI of ‘/info’. I hadn’t done this before with a Rails app, and I expected that it could be tricky. I checked online to see how this is done and found references to the ‘relative_url_root’ setting,…

Troubleshooting ActiveResource Requests
I’m currently working on an app which integrates with the HighRise API using the Highrise Ruby wrapper gem.
