I'm still only a short way through this fairly hefty tome of knowledge, but I'm already impressed at what "made the cut". Just the recipe covering how to use multiple databases (Recipe 3, 'Connect to Multiple Databases') is worth its weight in gold and I've learned a bunch from many other snippets. Overall the coverage is wide-ranging, the full gamut from Controller through UI, and the whole of Part VI ('Big-Picture Recipes') seems awesomely useful.
I would strongly recommend any learner or serious practitioner of Ruby on Rails purchase this book. You won't be disappointed!
