NoMethodError: undefined method `request='

Hello, I'm following along on the Railsspace Tutorial and I keep getting this one error. Any help would be appreciated. Sorry if this isn't enough information. What else would help?

Thanks a million.

Unless it's been updated, my understanding is that RailsSpace was written for an old version of Rails. The current version is 2.3.4; you might want to find a more recent tutorial.

Best,
