New to Rails and using Agile book second version?

With Ruby on Rails 2.1 version already here, I have seen a lot of new comers to Rails using second version Agile book asking this question again and again:

Why doesn’t my depot application work?

Well because it is based on version 1.2.3.

Here is a simple way to get it working.

• Delete your old Depot app.

• Install rails gem version 1.2.3 to support old apps

  sudo gem install -v=1.2.3 rails

• Recreate the depot app using the following command

  rails \_1.2.3\_ depot  

Using the above command will create app using version 1.2.3, otherwise rails will use latest version. - Enjoy!
