Assign Value of Named URL to a Variable in Django Templates

Question

In my Django template I need to assign the value of a names url into a variable within a with block so I can use it in multiple places.

I need to achieve something like this:

{% for tag in post.tags.all %}
    {% with tagabs={%url showtag tag%} %}
          <li><a href="{{tagabs}}">#{{tag}}</a></li>
    {% endwith %}
{% endfor %}

But obviously that doesn't work and would end up with a parsing error. The above example is a simple scenario where I could just have {%url showtag tag%} instead of {{tagabs}} and remove the with block. But in my scenario the tagabs value I need to use it in several places and within an if statement for comparison.

Thanks for the help.

Why create a new template tag/filter if the feature is in core?

Look the samples at: https://docs.djangoproject.com/en/dev/ref/templates/builtins/#url

{% url 'path.to.view' arg arg2 as the_url %}

<a href="{{ the_url }}">I'm linking to {{ the_url }}</a>

and

{% url 'path.to.view' as the_url %}
{% if the_url %}
  <a href="{{ the_url }}">Link to optional stuff</a>
{% endif %}
