[0.91] Model, subclassing, accessing superclass ?
hello hello I must be a bit dumb, but I find myself a bit stucked with model subclassing. Here's the problem: how does one call on the superclass method when extending this method in the subclass ? ie: class Parent(meta.Model): def my_method(self): do_something_here class Derived(Parent): def _pre_save(self): do_some_other_things_here Parent.my_method(self) # raises NameError, "Parent" is not defined parents.Parent.my_method(self) # idem, "parents" is not defined Is this a known issue, or I'm I missing something ? FWIW, the method I'm trying to extend is actually _pre_save() - but I don't think it has much to do with this problem.. NB : I've solved the problem at hand using a template method pattern as a workaround, but if the bug is - as often - between the chair and the keyboard, please let me know...
