This deals with the Rails book, but ActionWebService in general.
I''m having trouble getting the Rails book''s example in the Web
Service
chapter working. Everything else works (all the ''depot'' site
features up
to that point have been built and work). I don''t think it''s an
issue
with the book code being wrong, because the ActionWebService API docs
show almost the same example.
Since ActionWebService is not heavily documented and not widely used
(outside of Typo) I can''t quite figure it out.
When calling:
http://depot/backend/invoke
My error is:
<code>
Errno::ENOENT in Backend#invoke
No such file or directory -
/D:/Projects/Ruby/depot/public/D:/apps/ruby/lib/ruby/gems/1.8/gems/actionwebservice-0.7.1.1337/lib/action_web_service/templates/scaffolds/methods.rhtml
</code>
This is because of the "web_service_scaffold :invoke" line, as seen
below. I''ve also tried this by using an earlier gem version of rails
(0.12.1, instead of the current 0.12.1.1337 beta gem)
<code>
# app/api/product_api.rb
class ProductApi < ActionWebService::API::Base
api_method :find_all_products,
:returns => [[:int]]
api_method :find_product_by_id,
:expects => [:int],
:returns => [Product]
end
# app/controllers/backend_controller.rb
class BackendController < ApplicationController
wsdl_service_name ''Backend''
web_service_api ProductApi
web_service_scaffold :invoke
def find_all_products
Product.find(:all).map {|product| product.id}
end
def find_product_by_id(id)
Product.find(id)
end
end
</code>
Am I missing something (besides ''missing'' something)?
Curiously this
section of the book is the one part that has escaped an avalanche of
corrections/suggestions in the errata page.
Thanks in advance.

In a gem built locally, I have that file in the gems directory. Perhaps something on the system the beta gems are being built on excludes those files from the beta gem, I''ll need to investigate.

Fortunately it''s a moot point for the moment, as I managed to find the AWS manual (http://manuals.rubyonrails.com/read/chapter/68), and stumbled across the Rails trunk''s AWS examples (GoogleSearch), the combination of which has helped pull me out of the muck. I still cannot call the invoke action, but at least I can call /controllername/wsdl and get a response. Phew! For my next trick, I''ll be building out my rails app to interact directly with my .NET backend via web services. Initially I''ll have my .NET app call Rails AWS, but after that I''d like Rails to consume my .NET-generated WS (should I even hold my breath?). I''ll see how it goes... --Matt> >>Am I missing something (besides ''missing'' something)?
