I'm using rails admin with the following model types
When I'm editing a course instance I would like to see a button to create a new schedule. All I can see are the list of existing schedules but this is not really a correct view. Schedules are owned by a Course and the course_id field on Schedule should be immutable.
What I should be able to do is delete schedules from a course and add new ones but not reassign schedules. Has anybody got this kind of association working with rails admin in a nice way.
