How to pass template variable to tag in Django?

I try to pass a template variable to a tag as parameter, not sure how it works.

For instance

in template html

{{ question.author_id }}

{% monetize_slot question.author_id "questioner" %}

Here I can see the webpage show question.author_id as "2", but when I try to pass it via the tag monetize_slot, it treat it as a sta开发者_StackOverflowtic string "question.author_id", not a dynamic value 2. Does anyone find a solution for this here?

Thanks,

def monetize_slot(author_id, str):
  return '%s: %d' % (str, author_id,)
register.simple_tag(monetize_slot)

Works for me..

Try to define the template variable with {% with %}

{% with question.author_id as author %}
{% monetize_slot author "questioner" %} {% endwith %}
