Re: [Zope-dev] Folderish objects and multiple inheritance
Well if anybody is interested I did solve this but instead of trying to
inherit A, Folder and then fix the folderish methods broken I did Folder, A
and then overrode class A methods I wanted.

[Zope-dev] Folderish objects and multiple inheritance
Hi there,
Ok so I have a class that has multiple inheritance. My main class (A) works
fine, but I wanted to add in folderish properties. The problem is the order
of multiple inheritance and viewing folder objects. When you view a folder
from you call index_html and this gives a content list.
By inheriting this way:
class B(A, Folder):
I have kept all my A methods. However viewing it does not produce the
content list since its overwritten by A. Of course inheriting:
class B(Folder, A):
Does work for that, but breaks all my other methods.
Solutions:
Well I tried defining a tab - view_folder which was something along the line
of:
def view_folder(self, client=None, REQUEST={}):
''' doc string '''
return Folder(self, client, REQUEST)
But get an attribute error on manage_tabs.
Any ideas?
Thanks.
