#9177: list_filter cannot filter nullable fields ----------------------------------+----------------------------------------- Reporter: bthomas | Owner: nobody Status: new | Milestone: Component: django.contrib.admin | Version: 1.0 Keywords: | Stage: Unreviewed Has_patch: 0 | ----------------------------------+----------------------------------------- I have a model with a FloatField that is nullable. I would like to filter models that have that field set to null, so I added it to list_filter in my ModelAdmin class. When I select the "None" option, I get an exception from get_db_prep_value because it's calling float(None). I tried modifying get_db_prep_value for FloatField to return None if value is None or "None", which got rid of the exception, but did not return any results.
Will attach a patch if I figure out how to fix this to return correct results. ForeignKey fields that are nullable do not even display a None option in the filter, but I get a similar error trying to modify the query string to use None instead of an id. -- Ticket URL: <http://code.djangoproject.com/ticket/9177> Django <http://code.djangoproject.com/> The Web framework for perfectionists with deadlines. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django updates" group.
