Why not ask for username and password and verify the account by logging them in? If they can authenticate, then link the accounts?

Mike

Hi all,

I also have existing application with internal authentication, and we need to be able to import/install user’s widget ( combination of various choices that user selected during regestration) via Facebook app. I have a facebook application that does that without problems. But my question is what would be the bast way of linking facebook id to my local user account?

Currently i do the following

upon app instalation I ask user to put in his application’s login
I link his login ( if found ) with facebook_id

Though it works fine for me, there is a big security concern in it. Anyone can come in and just choose somebody else’s link thus overriding facebook id of the other user.

Any ideas, suggestions would be greatly appriciated on that topic.

BTW, really awesome book in couple of hours I was up and running.
Thanks a lot Mike

You could create a FacebookController class that includes the “ensure_application…” and then make all of your Facebook controllers descend from that.

The routing also isn’t that bad. You can do


map.with_options :conditions=>{:canvas=>false} do |non_fb|

  non_fb.resources :users
  # all other routes here
end

The Facebooker mailing list is a good place for these discussions. There are people on the list that have more experience integrating Facebook with an existing app than I do.

Hi all,

Mike I just finished reading your latest chapter and it’s pretty good. I’m wondering tho, What if I have an existing website that’s already in production and I’m creating a Facebook application to go with it? At first blush it seems to me that should I follow the guidance offered in your chapter and integrate my site with the facebook application that in reality what will happen is that my main site becomes subsumed by the facebook application. What I mean is that it feels like I would have to attach to all my routes the :canvas => false option, and all my non facebook controllers will need to have the before_filter to skip the application check. Is this observation true?

what I am thinking is that I would like to be able to segment the facebook stuff from my website stuff via something like separate routes, or checking the request in application.rb and setting things up to either render as html or render as fbml in the controller actions (just like you can render as :xml) (although I’m not confident that is a way to go).

I’m starting to develop a facebook application where factors influencing design/implementation point me to wanting to be able to separate out the facebook stuff from the main website to the point that they may have to be two separate applications in the future.

Do you (or anyone) know of other information/discussion forums on integrating FB into an existing app?
