[Zope] Persistence Module Confustion

[Jean-Francois.Doyon at CCRS.NRCan.gc.ca]

Your problem could be related to the allow_class ... allow_module take a
string parameter which is the parameter NAME.

To use allow_class however you need to first import it and pass the class
itself to the call.  Again: NOT a string, but the class itself.

For instance here's how I do it with a third-party module I have:

    from Projection import Projection
    allow_module('Projection')
    allow_class(Projection)

Hope this helps!

Actually I sorted this out. I didn't realize there was a MailHost option
in the pull down menu ;| As far as loading modules go I have been able to
solve this problem by creating my own custom Product and setting the
security declarations in __init__.py.

I am still having a problem importing a Python module I created containing
some class objects. I placed the module in the Products directory
and modified the __init__.py module accordingly. I've tried adding both
allow_module(<module_name>) and allow_class(<class_name>) to the __init__
file. Both don't seem to work even after restarting zope.

Any ideas?

Thanks
