A couple things: - Railsspace isn't the best tutorial to start with - the ideas are good, but trying to update a 1.2.3-era tutorial to present isn't the most helpful. It also re-implements a lot of things that have mostly been rolled into popular plugins (authentication for one; also this whole image upload bit).
- In general, always post as much backtrace from an error as you can. The final error is sometimes really just where the code fell down after wandering in the woods for a while. - Similarly, if you're troubleshooting a controller action, posting the log output for the action is handy as well; I've chased more than one bug in my own code that came down to a missing method= on a form, which shows up immediately in the log. - You are almost certainly missing something from the earlier chapters of Railsspace - I found the relevant discussion of routing (re: hub_url) in Chapter 9, Listing 9.39.
