Hi,

I am having problems with REST web-service support.

I have a simple controller:

class DocumentsController \< ApplicationController  
wsdl\_service\_name ‘Documents’  
web\_service\_api DocumentsApi  
web\_service\_scaffold :invoke

def list  
@docs = Document.find(:all)  
respond\_to do |wants|  
wants.html  
wants.xml { return @docs .to\_xml }  
end  
end  
end

Then, my api is defined as follow:  
class DocumentsApi \< ActionWebService::API::Base  
api\_method :list, :returns =\> [:string]  
end

But when running invoke web interface (same if real client), I got the  
following:  
Template is missing  
Missing template  
./script/…/config/…/app/views/contents/invoke\_submit.rhtml

What do I miss here?

Thanks you  
Jean-Etienne

I forgot this: if I modify the controller code to:  
def list  
@docs = Document.find(:all)  
return @docs.to\_xml  
end

It works fine like that (but of course this is not suitable)

You are trying to mix AWS with REST API. If you really need them to  
coexists, you shouldn’t use direct dispatching mode. See

In fact, I was just following  
[http://jamis.jamisbuck.org/articles/2006/03/27/web-services-rails-style](http://jamis.jamisbuck.org/articles/2006/03/27/web-services-rails-style)

But, I do not see how to call a controller from an AWS controller. Or  
did I miss something?

Kent,

Thank you. But changing the dispatching mode won’t help that much on  
keeping things DRY. Could you explain me? Or point to some resources?

Thank you
