Can anybody help me how should I create Server Application Programming Interface (SAPI) using Rails?

Answer 1

It depends on operation you want your API allows to do.

For example there is gem inherited_resources for RoR that generate resource methods for models.

You just need to create such controller:

class ProjectsController < InheritedResources::Base
    respond_to :xml, :json
end

and now you have API methods that can create, read, update and destroy records in your Projects table, and support two formats xml and json!

I think it is very convenient, but it depends on your purposes.
