- Only use JS for the drag&drop functionality and to the set/alter the time and rooms of the EventSchedule object.
- Introduce has_many :events, through: :event_schedules association to get unscheduled event easily
program.selected_schedule.event_schedules.order(start_time: :asc) was repeated several times and it has been moved to conference#selected_event_schedules
For the schedule versioning in the admin interface (having multiple possible shcedules) we need to change some models and associations. It has also been create a rake:move_events_attributes task to migrate the data.
User Interface addapted to make use of the introduced associations and models
The events are ordered by date and time in the all events section of the schedule. The event schdule definition in program has been changed to order the events.
