Hmm.. I know this is a python question, but DejaNews nor the Python website
give me the answers I am looking for:
I define a baseclass derived from CatalogAware and DTMLMethod:
class Base(CatalogAware, DTMLMethod):
def index_object(self):
# check a few things I want to know about
# before indexing, maybe even not allowing
# the indexing
CatalogAware.index_object(self)
Then I define a bunch of classes based on this base class:
class A(Base):
pass
class B(Base):
pass
etc.
Now, if I do the following:
a=A()
a.index_object()
I get a TypeError:
unbound method must be called with class instance 1st argument
Now, I have seen all sorts of messages relating this error, but none of
them seem to relate to my problem...
self in Vase.index_object _is_ a class instance, a step-by-step debug
proves this. The python interpreter just won't accept it =(.
