Instance Method Details

#new ⇒ Object

A major REST faux pas, our #new action actually creates something - an instance of a HomeDelivery::Event. We use this to render a modal form where the user can choose which drug types they want to print a PDF for, and what some parameters are for the PDF e.g. the prescription duration. See also Drugs::HomecareForm. The overall idea is that when you bring up the modal dialog to print a home delivery PDF there is always an Event object created behind it, and when you change the params (drug type, prescription duration) it updates the stored event, ready for printing. Although this means we might create rows that are never printed if the user cancels out of the dialog, this is OK as the #printed flag will not be set on those rows so they can be housekept away
