#web_service(name, object = nil, &block) ⇒ Object

Declares a web service that will provide access to the API of the given object. object must be an ActionWebService::Base derivative.

Web service object creation can either be immediate, where the object instance is given at class definition time, or deferred, where object instantiation is delayed until request time.

Immediate web service object example

class ApiController < ApplicationController
  web_service_dispatching_mode :delegated

  web_service :person, PersonService.new
end

For deferred instantiation, a block should be given instead of an object instance. This block will be executed in controller instance context, so it can rely on controller instance variables being present.

Deferred web service object example

class ApiController < ApplicationController
  web_service_dispatching_mode :delegated

  web_service(:person) { PersonService.new(request.env) }
end
