ActiveRecord + self.site dynamic url value

Hello Everyone,

I am using rails 4 version and i am using ActiveRecord to GET and POST
data
to other rails application.

Below is my product model code

// product.rb
require ‘active_resource’
class Product < ActiveResource::Base
self.site = “http://localhost:5000/
def other_method
true
end
end

My problem is how can i change site url which is in the product model
dynamically based on users selection. I have Site model, in that i have
list of sites. User should select one site when they try to create a
product…

Regards
