I'm building an adapter for Ruby's DataMapper for Salesforce. I've been able to use the WSDL with SOAP to make #query calls to Salesforce. However, I can't figure out how to use Ruby code to update an object (because Ruby's SOAP connector is not quite as snap-in as Java or C#'s connector).

The code I've been using to set up the connection is at: http://pastie.caboo.se/private/wcqjqv1icvshqpucsxupq

It's a little bit frustrating that Salesforce hung its Ruby hat on ActiveSalesforce, which is more a Rails/ActiveRecord solution than a general-purpose Ruby solution. Ideally, Salesforce would have built a low-level library to connect to its webservices, and then built ActiveSalesforce on top of it (the code for ASF is a mess, and includes a partial solution that someone was building prior to the release of ASF).

Anyhow, I'd appreciate any help someone could provide about making reliable #update calls back to the server for objects returned as a result of a #query call.
