delete all with has_many

Im not sure using :dependent => delete_all is correct here but I want to delete all the ApptEdits when an Appointment is updated in a certain situation. so i have:

@appt_to_edit.update_attributes(appointment_info)

and then i want to do something like:

@appt_to_edit.appt_edits.destroy

but this does not work. i was thinking about something like using :dependent => :delete_all, but i only want to do this after a specific update_attributes call and not every one so i dont think this is appropriate. what is the best way to write the equivalent to the pseudocode: @appt_to_edit.appt_edits.destroy?

@appt_to_edit.appt_edits.destroy_all
