hi all
i have a model with a modifed field
modified = models.DateTimeField(auto_now=True)
and a parent field
parent = models.ForeignKey('self', related_name='children', null=True,
blank=True)
in order to allow for creating a tree of items.
what is the best way to propagate a modification in a child to set all its
parents to the same modification time?
or is it possible to sort a query set that retrieves only the top-most items
(parent=None) on the latest modification time of its children? maybe using a
method that calculates and returns that date on the fly?
thanks a lot for your help
André
