Rails viewing nested attributes with xml Print E-mail
I've run into this problem many times with rails. I need to list out something and inside of this list may be other nested lists of properties.  I'm using two models for this example

CustomTask has_many StateChanges
StateChange belongs_to CustomTask


You would think a simple CustomTask.all.to_xml(:methods => ['state_changes']) would give you a nice list with nested state_changes, but unfortunately to_xml seems to not want to serialize this array properly. Also, forcing the :include in the find does nothing to help the to_xml either.

I've done this on multiple nested models and it always converts to xml much better. 

  def list
        custom_tasks = CustomTask.find(:all).collect do |ct|
                h = ct.attributes
                h['state_changes'] = ct.state_changes
                h
        end

        render :xml => custom_tasks.to_xml(:dasherize => false)

  end

If there is a simpler way, by all means, let us know and we'll post it here!
