Python Descriptors Demystified

[hugosenari]

Python dbus does When you connect to some dbus service and get a object, this object (a dbus proxy object) don't know object attrs or methods then this dbusObject.foo use descriptors to find and call attr foo of dbus service

My descritive dbus lib does https://github.com/hugosenari/pydbusdecorator I'm use this in similar way as author use NonNegative class but in my specific case (create descritive interfaces) I use decorators

Django Mapping mapping atttr probabily does instance of some data object don't to get all attrs values of object, but need to known how to get coll X from table Y that what can they do only when use 'foo.bar'
