Rails Savon gem keys in upper and lower case -

i'm using savon gem access soap api. thing is, api requires keys in uppercase , other keys in lowercase, can't use option convert_request_keys_to parameter.

this format of api need comply to:

<soapenv:envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xs="xmlservices">    <soapenv:header/>    <soapenv:body>      <xs:getrooms>          <xs:request>              <xs:credentials>                   <xs:credential1>"example1"</xs:credential1>                  <xs:credential2>"example2"</xs:credential2>                  <xs:credential3>"example3"</xs:credential3>          </xs:credentials>      </xs:request>  </xs:getrooms> 

as can see request lowercase, , rest uppercase.

this how use gem:

def call(method, attributes = nil)   attributes = { 'request': { 'credentials': attributes } }   response = client.call(method, message: attributes)   #do response end 

am calling right? there option i'm missing? need fork repository , modify gem myself?

okay, pretty simple:

just needed use option convert_request_keys_to :none
