Hi,

I found it difficult to work according to this book with the latest  
RoR release.

Please guide as to which RoR release to use.

Thanks…

Best Wishes,

No. Use the latest release (2.3.5). Find a book or tutorial that’s  
written for it. There is no reason not to start with the latest  
version.
