Set appid, appsecret of omniauth-facebook gem dynamically based on subdomain

Each customer in our ror app is served based on subdomain and they have their fbappid, fbsecretid (whichi powers the customers fb app). We use omniauth, omniauth-facebook for authenticating users. so customer1.ourapp.com serves an fb app with appid fbapp_1 and customer2.ourapp.com server with appid fbapp_2

normal way of initialization of facebook strategy is putting the following line in a initializer

config.omniauth :facebook, APP_ID, SECRET, {:scope => 'publish_stream}

We need to set APP_ID, SECRET based on the subdomain, but it looks like request object is not avaiable at the initializer time I looked into the dynamic setting of options using setup=> but omniauth-facebook doesnt seem to support setting of appid, appsecret dynamically.

How do we set the app_id and app_secret of omniauth-facebook dynamically based on subdomain of the request? thanks in advance

Since you are using devise, try

config.omniauth  :facebook, :setup => lambda{
      current_domain = // Get current domain
      config = // Get config
      env['omniauth.strategy'].options[:client_id] = config[current_domain][Rails.env]["app_id"]
      env['omniauth.strategy'].options[:client_secret] = config[current_domain][Rails.env]["app_secret"]
    }

http://webcache.googleusercontent.com/search?q=cache:zmBqDAomJ84J:blog.cedricbousmanne.com/+&cd=2&hl=en&ct=clnk provides the solution without devise, with just omniauth

[edited] Excerpt from working code

config.omniauth :facebook, {:setup => lambda{|env|
   env['omniauth.strategy'].options[:client_id] = $institute_tenant.fbappid
   env['omniauth.strategy'].options[:client_secret] = $institute_tenant.fbappsecret
}, :auth_type => 'https', :scope => 'email'}
