Well, I do have a db in there but it's just one users table, which i
really need only to pair the facebook id to the oauth tokens to make
the api calls. Unfortunately it's a 3-legged oauth so i'm kinda stuck
with having my own db. I'm testing now something like this:
map("/3rd_party/friends") do
use Rack::Facebook #checking the fb signature
run lambda { |env|
request = Rack::Request.new(env)
return Rack::Response.new(["Invalid Facebook signature"],
400).finish unless request.POST['fb_sig']
user = User.find_by_fb_id(request.POST['fb_sig_user']) #db query
...
oauth_stuff_i_am_still_working_on
....
}
end
Will rails connection pool mess things up if used in an actor? Right
now I'm really much more worried about the app being blocked in the
http call as the third party is acting wonky lately. Db load is not a
worry for now.
Let me know your thoughts while I get the oauth - revactor http going.
Giovanni
