I should have spent the extra 10 minutes trying out the 'property'
solution (rather than the several hours I've spent on the generic view/
pagination code).
Adding this code to the model works perfectly well.
def _link(self):
from settings import ACCESS_PATH
if self.mimetype == 'url':
return '%sredirect?location=%s' % (ACCESS_PATH, self.uuid)
else:
return '%sdownload/%s/%s' % (ACCESS_PATH, self.uuid,
self.filename)
link = property(_link)
I wouldn't mind, except I've used properties extensively before and it
never occurred to me to use them this time .... sigh.
Cheers,
Tone
