Got an unexpected keyword argument 'pzn'-CodePudding

I'm struggling with following problem:

fachbereich_detailview() got an unexpected keyword argument 'pzn'

The error tells me that there is something wrong with my urls. If I change the last part of the url to int:test, it tells me that the unexpected keyword argument is test.

The query 'product = Products.objects.get(pzn="existingpzn")' is working fine (Tested with shell).

view.py:
[...]
def fachbereich_detailview(request, pzn):

    context = {}

    try:
        product = Products.objects.get(pzn=pzn)
    except:
        return redirect('fachbereich')

    context['product'] = product

    return render(request, 'app/LoginArea/fachbereich_detailview.html', context)
[...]

urls.py:
[...]
path('Produkt/<int:pzn>/', views.fachbereich_detailview, name='fachbereich_detailview'),
[...]

html:
<a href="{% url 'fachbereich_detailview' product.pzn %}" >Mehr erfahren</a>

I just can't figure out what the problem is.

I hope that someone is able to help me!

Thank you in advance Nader

It is because you are setting integer in your url, but you are passing string to your view. Change your url to that:

path('Produkt/<str:pzn>/', ...),
