Django Template: Use translation in default_if_none

Question

How can I use a translated string inside a template for default_if_none ?
Usually you would use something like this: {% trans 'TRANSLATED STRING' %}

Example

{{ value|default_if_none:'TRANSLATED STRING' }}

Answer 1

You can store the translated string in a variable, like:

{% trans 'TRANSLATED STRING'  %}
{{ value|default_if_none: }}

It however might make sense to define a custom template filter [Django-doc] here.
