Reflection

Finding information on web
Most tutorails available on web are dealing with earlier versions of rubyonrails, instant rails.
Finding correct information is quite time consuming.

Scaffolding in rails
InstantRails 2.0 does not provide scaffolding option and this limits the effectiveness in a educational or training environment. However due to limitations with scaffolding in production environments has been a major reason for this.

Making progress
There are number of different varieties of software tools available, and versions of them available. This makes things difficult to achieve if you don't have the correct combination. I started following a tutorial that was showing how to use MySQL that comes with the instant rails. However it was displaying an error sometimes and I found SQLite3 much easier.
