As I’m still experimenting with this maybe someone here could answer that one:
I have PythonScripts or PageTemplates inside a folderish container in the tree:
root
- folder1
— object1
— folder2
—— script1
—— script2
—— template1
I’d like object1 to acquire script1, script2 and template1 from folder2 as if
they were attributes/methods of object1, though they’re not.
I’ve played around with modifying __of__ and tried some stuff with __getattr__
and __getattribute__, but no success so far.
A simple
def __of__(self, parent):
""" ... """
return self.__of__(self.folder2)
in the class of object1 is not working as it always returns "The object at
root.folder2 has an empty or missing docstring. Objects must have a docstring
to be published.“
the object1 class definitely has a docstring.
Any hints how to achieve what I’m trying? Wrong approach?
Best, Sebastian
