CodePudding user response：

You are not passing in the second argument in:

def programmingLanguageTutorial(request, prg_slug):

CodePudding user response：

You can use like keyword arguments and its accepted the same way, and its more explicit which argument is which.

Do like this:

<a href="{% url 'base:tutorial-page' prg_slug=p.slug prglangcat_slug=p.slug2 %}"  </a>
