[ckan-dev] what is the Missing class used for?

[Dave Caraway]

Hi everyone,

Can anyone explain where instances of the Missing class (an exception) in
ckan.lib.navl.dictization_functions.py should be propagated to? Right now
they are going uncaught, resulting in a server error for me. Wondering if I
should just catch them and add a message to the error object.

code snippet from ckan.lib.navl.dictization_functions.py:

class Missing(object):
    def __unicode__(self):
        raise Invalid(_('Missing value'))
    def __str__(self):
        raise Invalid(_('Missing value'))
    def __int__(self):
        raise Invalid(_('Missing value'))
    def __complex__(self):
        raise Invalid(_('Missing value'))
    def __long__(self):
        raise Invalid(_('Missing value'))
    def __float__(self):
        raise Invalid(_('Missing value'))
    def __oct__(self):
        raise Invalid(_('Missing value'))
    def __hex__(self):
        raise Invalid(_('Missing value'))
    def __nonzero__(self):
        return False


Thanks!
-Dave
