Hello Guys,

Why the template tag call {% get_percentage question.pk choice.pk %} works inside the span tag, but doesn't work in style (width) attribute?

What is wrong?

 {% for choice in question.choice_set.all %}
        <strong>{{ choice.choice_text }}</strong>
        <span class="pull-right">{% get_percentage question.pk choice.pk %}%</span>
        <div class="progress progress-danger active">
            <div class="bar" style="width:{% get_percentage question.pk choice.pk %}%"></div>
        </div>
 {% endfor %}

I am using Python 3.5.2 and Django 1.10.2

PS: I did the same question on StackOverflow: http://stackoverflow.com/q/40065604/5498125, but I have no answers yet.

No idea. You haven't provided what your template tag does, or what the rendered template looks like.

What does the final HTML look like?

Hi Aline,

It is not direct answer for what you are asking,

but why do you calculate the percentage 2 times?

Why just use `with` tag?

With it nor problem at all.

Hope that helps.

Regards,

Constantine C.

Thank you both, Constantine and James. Thanks to your comments I could realize where the error was, and I could improvve performance assigning the returned value to a variable.

The error was in html, and not django. When I looked at the rendered html, I could see the error.
