We came across a use case today for wrapping variables in styles If they
are not None/Empty/False...[[BR]]
E.g. If a variable exists add a break tag after it or if a value exists
then wrap it in a <p></p> tag.
So we wrote a simple template tag that might be of interest to the
community.
Template tag:
{{{
from django import template
from django.template.defaultfilters import stringfilter
from django.utils.safestring import mark_safe
register = template.Library()
@register.filter
@stringfilter
def wrap(value, arg):
if value and value != '':
return mark_safe(arg % value) # decision needed with |safe
return value
}}}
Usage:
{{{
{{ var|wrap:"%s<br />" }} or
{{ var|wrap:"<p>%s</p>" }}
}}}
