How to link directly to the newest course from the homepage?

Hi everyone,

I am trying to make an anchor tag for the newest course on the homepage, however when I try to make the url I get an error. It seems like you cannot have nested tags. I was trying the following:

<a href="{% url 'courses:detail' pk={% newest_course %}.pk %}">{% newest_course %}</a>

Would anyone else be able to provide a solution to this?

Thanks!

Have you tried:

<a href="{% url 'courses:detail' pk=newest_course.pk %}">{% newest_course %}</a>

divide_by_zero.rb:2:in `/': divided by 0 (ZeroDivisionError) . Doesn't work.

newest_course.pk doesn't give the pk instead returns an empty string based on the error observed (see below)

NoReverseMatch at /courses/

Reverse for 'detail' with arguments '()' and keyword arguments '{u'pk': ''}' not found. 1 pattern(s) tried: [u'courses/(?P<pk>\\d+)/$']
