Yea I noticed this and now I'm leery about buying more books.

I want to add a very simple blog type application that lets a user enter text and create a blog (I know there are plenty of free blogging programs, but I want to build something simple for myself). I would also like visitors to leave simple comments. I figure this is a great project to learn and practice the fundamentals. I also figure this is a good project to practice using a database. Will these guides help me in this regard? >> My current problem is this: >> >> Following Chapter 9 in "Ruby on Rails for Dummies" we are trying to >> build a website for Photos.

I'll try going back to my editor. The thing I liked about the IDE was that it's more visual and it's easier, but the easiness becomes a handicap and when something doesn't work, you have more trouble figuring out why. >> Ruby 1.8.6 >> and I believe Rails 2.2 >> > > Why start off on an old version of Rails? 2.3.2 is current.
