Facebooker talk - Oct 2008 - why does ensure_authenticated_to_facebook request app install?

When I get redirected by ensure_authenticated_to_facebook it asks me
to install the application..  is this by design?  I just want to make
sure the user is actually logged in to facebook.

Nope, you just need to check for:

params[:fb_sig] && params[:fb_sig_added].to_i == 0

If the user clicked a link from Facebook to get to your app, there
will also be a "fromhash" parameter present too, which means
you''ll
have access to the users'' Facebook ID through
params[:fb_sig_canvas_user]

You''ll find that params[:fb_sig_canvas_user] isn''t as useful
as you''d
like since as I mentioned, it only comes up if you click a link from
inside Facebook. Unfortunately, clicking a bookmark does not seem to
work. The conclusion being that most of the time you won''t be able to
access a user''s Facebook ID unless they actually install the
application.
