I need a one-to-many to behave like a one-to-one.
The parent instance of my model can only ever have one current child
instance of another model. Multiple child instances have to exist and be
kept for the historical record.
The main benefit of one-to-one relationships is that they can be mapped
together (in the Admin) as an extension of the parent.
In a view I suppose I can use a manager to filter the children into a
pseudo-one-to-one thingy but how do I do this in the Admin?
Maybe sort them into date order and only show one? Is there a better way?
Thanks for any help
Mike
