This tiny template filter saves you the tedious test "if this variable is set, print this text based on this variable".
'verbose' filter takes one parameter : a string containing '%s' which is a placeholder for the value to test. Check those examples :
-
Replace this :
{% if name %} Hello {{ name }}, this is a dummy text {% endif %}
-
By this :
{{ name|verbose:"Hello %s this is a dummy text" }}
This is also usefull for HTML :
{{ image|verbose:"<img src=\"%s\" />" }}

register = template.Library()
@register.filter
def verbose(value, arg):
try:
if not value:
return ''
return arg % value
except Exception:
return str(value)

Good stuff, very handy. If used for HTML as in the last example, don't forget to tag on the |safe filter, too.
