How to convert records including 'include' associations to JSON

Question

If I do something like:

result =  Appointment.find( :all, :include => :staff )
logger.debug { result.inspect }

then it only prints out t

Answer 1

:include is an argument for to_json, not find. What you need to do in your controller is this:

def return_json
  @appointment = Appointment.find(:all)
  respond_to { |format|
    format.json { render :json => @appointment.to_json(:include => :staff) }
  }
end

You need to setup an association between Appointment and Staff for this to work.
