Hi Can anybody give links to(ebooks,tutorials) understand relations,callbacks and validations of Active Record more deeply
Sijo
There's the start of a set of related links here: http://www.buildingwebapps.com/topic/73-active-record
There's some useful screencasts at Railscasts.com.
If you're willing to buy a printed book, you'll find lots of useful material in The Rails Way (the best current book for anyone who wants to dive deeper into Rails), There's also an entire book devoted to Active Record (Pro Active Record), which has lots of detail but also some inaccuracies (see has_many :through - Book Review: Pro Active Record). I suspect it will be a much better book in its second edition. You can purchase that book as an ebook from the book's web site (http:// apress.com/book/view/1590598474).
