Question

Using the current rails 2

I want users to be able to create an account from:

• traditional signup
• twitter
• facebook

and then allow them to link facebook and/or twitter and/or traditional signup later.

I read this http://www.themomorohoax.com/2009/02/21/rails-2-3-authentication-comparison
and decided to check out:

• Authlogic
• Restful Authentication
• Devise/Warden

It seems for at least some of the plugins you can use with them that making OAuth work with them will make them incompatible with any other login system.

Will I need to roll my own from the ground up, or can I glue together some existing pieces?

Answer 1

You can glue together existing pieces.
I wouldn’t advise for Restful Authentication. It’s getting old and isn’t maintained anymore.

If you plan on using Authlogic, you can take a look at those two gems :

• authlogic oauth for any oauth service (including twitter)
• authlogic facebook connect

If you plan on using Devise, you can take a look at those two gems :

• warden oauth for any oauth service (including twitter)
• device facebook connectable
