title: Rails - User Input for Multiple models on a single form - How
body: <p>This is basically a nested form question, albeit with only one field that belongs to a parent model. My data entry form collects data for a model - however I also need to collect one other a data element/value (UserID) that actually goes into a parent record that will be created with the detail record. </p>
  
  <p>AFAIK Rails expects each form field to map to a model and I need to create an unbound data input field that I will use separately.  </p>
  
  <p>How can I override this default behaviour and create a'free form/unbound field'? </p>
  
  <p>TIA,
  BC</p>
