Databasedotcom gem：根据会话ID检索用户信息

Question

I am using databasedotcom gem for interacting with salesforce. I am able to get sObject(Account,Contact,Lead) info. Can any one tell me how to get the user info by passing salesforce session id.

Below code is used to get Account detail from salesforce, but i need to retrieve User info based on session id

client = Databasedotcom::Client.new("config/databasedotcom.yml")
client.authenticate :username => 'xxxxxx', :password => 'xxxxx'
client.sobject_module =SFDC_Models
client.materialize("Account")    
@acc = SFDC_Models::Account.all

After days of working on this, it turns out the :token parameter is the same as the Session ID. Nothing about this is documented, but hopefully it can help someone else in the future.

class HomeController < ApplicationController
        def create
                @session_id = salesforce_params[ :sid ]
                location_split = salesforce_params[ :url ].split("/")
                @location = "http://" + location_split[2]     

                client = Databasedotcom::Client.new                    
                client.authenticate :token => @session_id, :instance_url => @location
                render :text => client.list_sobjects
        end

        private def salesforce_params
                params.permit( :sid, :url )
        end
end
