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.

No need to reinvent the wheel with file uploads, I've used PaperClip to handle uploaded images and files with little trouble. It's very easy to configure as to where the information gets stored - in the database or out. On Oct 31, 8:47 am, RubyonRails_newbie craigwest...@googlemail.com wrote: Hi Everyone!

Any ideas why this issue is appearing then?? NoMethodError in AvatarController#upload You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base.

Fred's right.

[Rails] Re: *** PLEASE HELP!! *** NoMethodError in AvatarController#upload
You probably could have included that error in your post. I don't see .delete in your method, so I'm guessing it's somewhere deeper. Typically, error messages have line number, so that's something to check.
