[Zope-CMF] updatePredicate arguments?

[marc lindahl]

After blowing a day on this, I answered my own question.  Here it is so
noone else has to blow a day.  Bottom line?  'Record' is an obscure class in
HTTPRequest.py, of questionable value (why didn't they use a dictionary??)

To use it with updatePredicate, first you need to import it:

from ZPublisher.HTTPRequest import record

Then instantiate it and fill it with the appropriate values.  That varies
given the type of predicate.  This example is for the major/minor type:

    predicate = record()
    predicate.id = 'audio'
    predicate.major = 'audio'
    predicate.minor = ''
    registry.updatePredicate('audio', predicate, 'Audio')

...obviously, from an install script for CMFAudio...
