[Zope] ZClass Question

[Kevin Dangoor]

Hi,

    I had originally been thinking that ZClasses would allow you to override
ZClass-level methods, etc. with methods at the instance level. But, this is
not the case... and you're also not able to edit the methods for each
instance, as you have found.

    I have a solution to this, and I should probably write it up in a HOWTO
because this has come up a couple of times. If you download KM|Net News, you
can see my solution pretty easily.

    In the KMArticleStore ZClass, there are methods labelled
"default_article_header" and "default_article_footer", etc. The
KMArticleStore_add method will automatically take the contents of those
methods and copy them to the new instance. I have also added a view called
"Defaults" which allows the user to easily restore the defaults. One side
note: make sure you map the Access Contents Information property on your
"default" methods.

    I'll try to write a complete howto about this in my copious free time.
Hopefully, the paragraph above will point you where you want to go...

Kevin
