Accessing the request body of a SOAP request with Savon (Ruby on Rails)

Question

I'm using Savon gem in Ruby on Rails to communicate with a wsdl WS. Everything is working fine, but I want to log the request XML using a custom log, i.e. not Rails or Savon logger. My code looks something like this:

    response = self.client.request :add_order do
      soap.body = { 
        :indata => {
          "CustomerNo" => config[:kundnr],
          "Pwd" => config[:password],
          "OrderDate" => order["purchase_order_date"].strftime('%Y%m%d')
        }
      }
    end

Accessing the response is no problem, but what about the request? I need to be able to see what has been sent in my production environment by logging the XML to a DB-field.

Right now there's no easy way to get the request XML. But as you noticed, Savon logs each request and response to a specified logger. So if you're not changing the log level, you could use a custom Logger-like object that responds to :debug and store what gets logged.

module DBLogger
  def self.debug(message)
    p message  # replace with custom impl.
  end
end

Savon.configure do |config|
  config.logger = DBLogger
end

Hope that helps!
