Re: Python 2.3 and booleans

        Hi Yannick,

  Not sure I fully understand what effect you want here, just in case
this can help: you can transform any attribute's value stored as an int
in the db into py2.3 boolean automaticall=y by using a KeyValueCoding
private setter, like that:


    def _setMyAttribute(self, value):
        self.value=bool(value)

(this is in fact the very same technique exposed here:
 http://modeling.sourceforge.net/UserGuide/attribute-custom-type.html)


    If it's not what you need, could you also give a little example?

(admittedly I've read your msg quickly and answering the same way...)

  and I'll have a look at Arch when I find time ;)  Any idea on whether
  it wirks on sf?
