I am Malek I am working on a blog using django
but I am facing this problem with the url and pk
Reverse for 'detail' with arguments '('',)' not found. 1 pattern(s) tried: ['post/(?P<post_id>[0-9]+)/\Z']
I hope someone can help me solve this problem

def index(request):
if request.method == "POST":
contact = Contact()
user_name = request.POST.get('name')
email = request.POST.get('email')
subject = request.POST.get('subject')
contact.name = user_name
contact.email = email
contact.message = subject
contact.save()
return render(request, 'sent.html', context={'link': Navlink.objects.first()})
return render(request, 'index.html', context= {
'about_us': AboutUs.objects.first(),

I tried many ways but no one of them worked with me
You use b for the Blog object (I would advise using blog but anyway), that means you access the post id with b.pk, so:
<a href="{% url 'detail' b.pk %}">…</a>
