Where (what function name must I insert in my controller, I assume)
can I obtain the selected value from a field in a form, to process and
change it before it gets written to the model’s table in the db?
Thanks, Janna B.
Well, you could choose the ugly path and just place that code in the
controller create and/or update methods, after your model is
reconstituted from the params.
Or choose a better path and place that code in a method in the model,
and define a before_save in the model that invokes the method
(before_save is called for either create or update).
