Very disappointed with the quality of this book and in particular its source.
Even basic precautions like locking the gems to particular versions and including them in vendor cache haven’t been followed, so doing a bundle install on the code results in
- Devise wanting to rewrite all its configuration as its moved on so much
- Formtastic forms blowing up as the buttons api is now obsolete.
So trying to use the source to make some sense of the confused narrative of the book is a really frustrating experience
