django NoReverseMatch at /account/dashboard/1/ - django

Question

I have a problem when I want to visit the user dashboard. On each article there is a link to the user profile, however, when I click on the link I'm getting NoReverseMatch. I was doing troubleshoots for days but I'm not able to fix the problem. Any help on how to fix this error is more than welcome, thank you!

return render(request, 'account/dashboard-guest.html', context = {'user_other' : user_other, 'already_followed' : already_followed})

Answer 1

In the template, you have <a href = "{% url 'article_detail' pk=article.pk %}", but the variable article is not created anywhere. Where should it come from?
There is a loop {% for user_other in user.article_author.all %}, and it seems like it should somehow lead to an article, but that's unclear without the models and business logic knowledge. Should it be {% for article in user.article_author.all %} ?
