Hello,
Is it possible to store and load an ordered list of items with SQLObject?
In my specific case, I have a recursive data structure:
class Knowledge(SQLObject):
parent = ForeignKey('Knowledge')
children = MultipleJoin('Knowledge', joinColumn='parent_id',
orderBy='pos')
pos = IntCol(default=0)
How do I make sure "pos" is assigned the correct value when I add
children to a node? Should I override _set_parent() or addChildren()?
Or should I manage the list of children myself using a "hidden" field
which implements the DB access to load all children?
Regards,
