[SQLObject] Joins

[Michel T. <mic...@ya...>]

Hi people!

See this:

>>> class Barrel(SQLObject):
...   monkeys=MultipleJoin('Monkey')
...
>>> class Monkey(SQLObject):
...   barrel=ForeignKey('Barrel')
...
>>> barrel=Barrel()
>>> monkey=Monkey(barrel=barrel)
>>> isinstance(barrel.monkeys, (list, tuple))
True

Why this is true? Why can't the join return a select object, this way,
if I need to count the monkeys of a barrel, I can use
barrel.monkeys.count(), I can use sum() and other aggregate function I
want... The actual way I need to rewrite the join to be able to apply
these aggregate functions, or I use python to calculate what I need...

Is there a disvantage on using python to make the calculation? Does my
worry has foundation? Thanks for all help!
