[Facebooker-talk] Facebooker and existing website?

[Christopher Bailey]

One thing you may want to consider is using a combined user model.  This way
you can associate your regular (non-Facebook) users and their Facebook
account.  What's cool about that, is that if they take some action on your
regular web site, you can say update their Facebook profile box for your
app.  This is what we do, as do many sites.
To do so, one approach at least is to add columns to your regular user model
to store their Facebook persistent session and id, etc.  The caveat is that
you then need to add conditional logic to differentiate things at times.
 You also need to deal with synchronizing/associating their regular user
with their Facebook user, but honestly this is pretty easy.  In the app I'm
working on, when they add the Facebook app, it tells the user they need to
associate with their regular site account (we require this), and it sends
them over to our site, they login, and in that process, we store off their
Facebook infinite session key, and then redirect back to Facebook.  Again,
this is straight forward to do.

With that setup, then you can just have a before filter on your Facebook
controller(s) that check that the person has installed the app, by doing the
equivalent of User.find_by_facebook_session_id (or whatever you called the
column) or similar, etc.
