I'm trying to write a filter that will highlight substrings in text
that matched a search pattern. I was hoping to do something like this:
{{ obj.field|highlight:search }}
where 'search' is a template-context variable that is the string the
user was searching for and the highlight filter would look something
like:
@register.filter()
def highlight(value, arg):
s = template.resolve_variable(arg, c) # WHERE DO I GET THE CONTEXT
FROM?
return re.sub('(%s)' % (s,),
r'<span class="hightlight">\1</span>', value)
But I don't see a way to reference the template context ('c') in my
filter, nor a way to pass the value of a variable from the template.
Any ideas?
