Which is the best way to create a login in Rails for a starter?
authentication, database, ruby, ruby-on-rails
Solution
Other answers are recommending Devise. Devise's own documentation says:
If you are building your first Rails application, we recommend you to not use Devise. Devise requires a good understanding of the Rails Framework. In such cases, we advise you to start a simple authentication system from scratch.
I'm inclined to agree. Devise is a great engine that can create a powerful login system for you in minimal time, but if you're building an app for the purpose of learning Rails, I'd recommend following a tutorial to build your own login system so you get a deeper understanding of what's actually going on beneath the hood. You can always come back and use Devise later.
For a tutorial, I'd recommend the same book that Devise recommend, Michael Hartl's Ruby on Rails Tutorial - specifically chapters 6, 7, 8. (Well, I'd recommend the whole book, but those are the chapters that pertain to building a login system.)
If screencasts are more your thing, Ryan Bates's Railscast on the subject is supposed to be good although I haven't watched it myself.
Problem
I've seen there're several engines and tutorials about it, but I couldn't figure out which one could help me out in short terms. I'm just learning Rails and Ruby and my aim is to understand how it works while it can be useful in a real life event. Any link or explanation about this will be kindly appreciated!
