Hi, I needed to create a fault message in a XML-RPC ws. The only tip I've found says to raise a FaultException giving the faultCode and the faultString. But testing with the scaffold I get: NoMethodError in UserController#invoke_submit
You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.collect
Here's the api implementation:
class UserController < ApplicationController wsdl_service_name 'User' web_service_scaffold :invoke def create(email, password, first_name, last_name, phone)
if first_name == "admin" raise XMLRPC::FaultException.new(3, "admin is not allowed...") else return 0 end end end
In the development log looks like the raised exeption correctly builds the answer: Web Service Response: => #<XMLRPC::FaultException: XMLRPC::FaultException> <?xml version="1.0" ?><methodResponse><fault><value><struct><member><name>faultCode</name><value><i4>3</i4></value></member><member><name>faultString</name><value><string>admin is not allowed...</string></value></member></struct></value></fault></methodResponse> Sending data
but then something happens and I have no clue. Thanks, Enrico
ps this is the complete development log file:
