Nov 22, Paul rated it really liked it. I recently got my hands on a review copy and was quite interested to see if it was worth a recommendation. A book like this has to be current.
Happily this edition covers Rails 4 and Devise 3, and code examples worked fine for me with the latest point releases. The book is structured primarily as a primer and tutorial, perfect for those who are new to devise, and requires only basic familiarity with Rails. Tutorials are best when they go beyond the standard trivial examples, and the book does wel I recently got my hands on a review copy and was quite interested to see if it was worth a recommendation.
Tutorials are best when they go beyond the standard trivial examples, and the book does well on this score. It covers a range of topics that will quickly become relevant for anyone actually trying to use devise in real life. Beyond the basic steps required to add devise to a Rails project, it delves into: Unit and RSpec I particularly appreciate the fact that the chapter on testing is even there in the first place!
These days, "how do I test it? The topics are clearly demarcated so after the first run-through the book can also be used quite well as a cookbook. It does suffer from a few cryptic back-references in the narrative however, so to dive into a chapter cookbook-style you may find yourself having to flip back to previous sections to fill in the dots. I think some extra effort on the editing front could have improved this along with some of the phraseology, which is a bit stilted in parts.
1. Devise – Authentication Solution for Ruby on Rails - Learning Devise for Rails [Book]
Authentication has always been a critical part of Rails development, but since Rails 3 in particular I think it is fair to say that devise has emerged as the mature, conventional solution for now! So I can see this book being the ideal resource for developers just starting to get serious about building Rails applications. It will give enough foundation for moving to more advanced topics not covered in the book such as developing custom strategies, understanding devise and warden internals.
Dec 02, George Tinix added it. Imagine that you create a cool Rails web application that does different things for different users. To do so, your application needs to be able to identify users at least users who are logged in versus anonymous visitors to restrict its many functionalities. Before building your core Rails application logic, you will need a few authentication-related features working, that is, sign-up, sign-in, sign-out, remember me, and password reset features.

In future, you will want to integrate the login with Imagine that you create a cool Rails web application that does different things for different users. In future, you will want to integrate the login with social networking sites such as Facebook or Twitter, so that your users will not need to retype all their details when signing up for, or signing in, to your web application. Jan 27, Arief Hidayatulloh rated it it was amazing. Devise is a flexible authentication solution for Rails based on Warden. It is amazing, we can create authentication module very fast.
We can learn our application authentication from this book. It can create sign up, sign in, update, and delete user. Devise has build-in function for email confirmation module too. Do you want to connect your web with Twitter or Facebook? This book explain how to authenticate to Facebook and Twitter. As others have said, unless you have a pressing need, just follow the tutorial. You will learn a lot of good things from it, and using Devise will cause you to miss a lot of great information. The idea is that, as a noob, learning the basics of how authentication works is really useful.
Even if in future projects you end up using Devise all the time, having the experience of developing your own authentication so you know what's going on behind the scenes in Devise is really helpful. You need to make your own decision on this. If you're in a hurry to get an app out the door, learning how to use Devise first might be the right way to go. If you have the time though, trying to figure out how to roll your own is a good idea. At the very least, it's worth your time to check out Ryan Bates video on rolling your own: Also, this from the Devise documentation discouraging new rails devs from using Devise: Why shouldn't rails noobs use Gem Devise?
Why shouldn't a noob use devise for his own project?
Thanks for any tips at all but I would much prefer a verbose answer. Alain Goldman 1, 4 31 Do you always listen to people who tell you you can't do things? If you manage it, good, if you don't, ask for help. Your current question, however, is off-topic. If anything it's badly phrased, but it's a legitimate question in my opinion.
I agree in principle. But there are many other things that could put your users at risk. Building applications without having any real knowledge of how the framework or the language work could pose the same risks.

I would argue that you should not be building a serious app before you know the fundamentals of security. Using Devise will not teach you this. So your argument is that because you can make mistakes elsewhere, you shouldn't care if you make mistakes with auth? If you don't make mistakes you'll never learn.
Using a gem may help you avoid mistakes, but it neither makes your app safer nor you a better programmer. It doesn't take a genius to write auth. Auth is built on abstraction libraries; you're not reinventing the wheel or writing cryptography. You're utilising an API.
