Reverse for with no arguments not found for URL - django

Question

I am attempting to create a view that allows users to delete a build log. On the view that shows the delete button with a link to the delete page I am getting the error
Reverse for 'build-log-delete' with no arguments not found. 1 pattern(s) tried: ['post/(?P<pk>[0-9]+)/build\\-log/(?P<pkz>[0-9]+)/delete$']
If I understand this error correctly its because I am not passing paramaters in the url.
<a class="delete-btn" href="{% url 'build-log-delete' %}">Delete</a>
However I do not understand why I need to pass parameters in the URL as I am not passing any new values into the URL and if so what parameters I would pass. Do I have to re pass the previous two?
urls
path('post/<int:pk>/build-log/<int:pkz>/', views.BuildLogDisplay, name='build-log-view'),
path('post/<int:pk>/build-log/<int:pkz>/delete', views.BuildLogDelete, name='build-log-delete') #error
views
def BuildLogDisplay(request, pk, pkz ):
post = BuildLog.objects.filter(post_id=pk)
log = BuildLog.objects.get(pk=pkz)
context = {
'post':post, 'log':log
}
return render(request, 'blog/buildlog.html', context)
def BuildLogDelete(request):
context = { }
return render(request, 'blog/BuildLogDelete.html', context)
full template
<div class="row">
<article class="cars-article">
<div class="flex">
<img class="rounded-circle article-img" src="{{ log.author.profile.image.url }}" />
<div>
<a class="article-title">{{ log.title }}</a>
</div>
</div>
<br>
<div>
{% if log.author == user %}
<a class="update-btn" href=""> Update</a>
<a class="delete-btn" href="{% url 'build-log-delete' %}">Delete</a>
{% endif %}
</div>
<hr class="solid">
<p class="article-content">{{ log.content | safe}}</p>
</article>
</div>

There are multiple errors in you code. You are not passing args in BuildLogDelete view but in url you are using those arguments. So the correct view should look like this.
def BuildLogDelete(request,pk,pkz):
# delete code
# write here
Next mistake which i can see is you are assigning queryset rather than object for the post key in BuildLogDisplay view. You should assign object.
post = BuildLog.objects.get(post_id=pk)
Lastly your original error mentioned in the question is because your build-log-delete url expects two arguments i.e pk and pkz but you haven't passed them in template. So it should be like this.
<a class="delete-btn" href='{% url "build-log-delete" pk=post.post_id pkz=log.pk %}'>Delete</a>
I would highly suggest you to look for already given generic views like ListView, TemplateView, CreateView, UpdateView and DeleteView. This will prevent you from reinventing the wheel
