I have an events listing site that includes the models Event and DateAndTime, so an event that happens more than once (like a high school play) can have more than one date\_and\_time. The Event model has\_many date\_and\_times, and the DateAndTime model belongs\_to event. The Event model validates\_presence\_of two submission form variables, the\_date and the\_time, and those variable values then get used to create a new date\_and\_time object once the form is submitted. My ActiveScaffold problem is that when the update form for the Event model displays, it shows all the correct dates and times in drop-down lists (with the ability to either edit or delete them) PLUS an _extra_ date and time field that’s set by default to the current date and time, with no way to delete that field. The update form is created with this new additional date field required, even though the event object already has other date\_and\_time objects associated with it. Any ideas how I can make my Event update form display without the new date and time non-deletable field in ActiveScaffold, while still requiring date and time submissions on the public site’s Event creation form? Thank you.
