Django template tag to show null date as "still open" -

i have following code in django template:

{{date_from|date:"y-m"}} - {{date_to|default_if_none:"still open"|date:"y-m"}} 

i get:

1. "2012-08 - "
2. "2012-11 - 2012-08"
3. .. rest of values correctly displayed.

i this:

1. "2012-08 - still open"
2. "2012-11 - 2012-08"
3. .. rest of values correctly displayed.

do have suggestions? think not displayed because date object.

change order of filters. use default instead of default_if_none (date filter return empty string non-date/datetime object)

>>> t = template('{{date_to|date:"y-m"|default:"still open"}}') >>> t.render(context({'date_to': none})) u'still open' >>> t.render(context({'date_to': datetime.datetime.now()})) u'2014-04'
