Using Django template tag "with" with the result of another template tag

I have a comment_form.html template, which is used in multiple places in my app, and I'd like to be able to pass the endpoint's url into that template from a parent template. Normally I would do this using the with tag:

{% with endpoint='/comments' %}
    {% include 'comment_form.html' %}
{% endwith %}

The problem is that I can't use a string literal '/comments' here, but instead I need a url tag, like so: {% url 'blog:comments:comments' username=post.user.username object_id=post.id %}. The with template tag seems to expects a literal or a context variable and doesn't seem to be able to comprehend "use the result of another template tag".

One solution would be to pass the strings 'blog:comments:comments', post.user.username, post.id all separately. But this is a problem because different uses of the comment form may require different arguments to uniquely define the endpoint.

How can I use with with the result of another template tag?

You can't, but you don't need to. The url tag has an alternative syntax that injects is result into the context:

{% url 'blog:comments:comments' username=post.user.username object_id=post.id as endpoint %}
