Rails Scaffolding

Rails Scaffolding was created to make things easier for you. So rather than using a tutorial that isn't correct and losing your mind for hours (like myself) do yourself a favor and check to see what version of rails you are running first.

Open a terminal and type "rails -v" to check which version of rails you have installed:

Mine says "Rails 2.3.4" so I will make sure i'm using a Rails 2.0 Scaffolding tutorial like the following:

- or -

If you get anything lower than Rails 2.0 you should be using the Rails 1.0 examples like the following:

Ruby on Rails Setup

Since I'm running Mac OS X 10.6.1 (Snow Leopard) I found a lot of useful information on Apple's Developer Connection page: Using Ruby on Rails for Web Development on Mac OS X.

I must warn you that the information for Rails Scaffolding wasn't correct for the current version (Rails 2.3.4) I was running. If you have no idea what that is, don't worry you can still proceed. I would however stop at that part of the tutorial and check out my post for Rails Scaffolding.
