Django: comment_create() got an unexpected keyword argument 'pk' error - django

Question

I am now implementing a comment function on the post_detail page.
but occurred comment_create() got an unexpected keyword argument 'pk' error.
I also tried to change the def comment_creat(request, post_pk): part to def comment_creat(request, pk): on views.py.
and I try {% url 'comment_create' pk=post.pk %} --> post_pk=post.pk
views.py
#login_required
def comment_create(request, post_pk):
if request.method == 'POST':
post = get_object_or_404(Post, pk=post_pk)
content = request.POST.get('content')
com_user = request.user
if not content:
messages.info(request, 'Write please')
return redirect('post_detail', post_pk)
Comment.objects.create(post=post, comment_user=com_user, comment_content=content)
return redirect('post_detatil', post_pk)
urls.py
path('post_detail/<int:pk>/comment_create/',views.comment_create, name='comment_create')
post_detail.html
<form action="{% url 'comment_create' pk=post.pk %}" method="POST">
{% csrf_token %}
<input type="text", name="content", placeholder="comment...">
<input type="submit", value="Go">
</form>
Please help me.

Answer 1

In your view, the name of the argument is post_pk:
#login_required
def comment_create(request, post_pk):
# ...
but in your URL patterns, you use just pk:
path('post_detail/<int:pk>/comment_create/',views.comment_create, name='comment_create')
You can rename any of the two, but renaming the parameter in the urls.py, will result in updating all {% url ... %}s for that view as well, so it is likely that renaming the parameter in the view, will result in less editing:
#login_required
def comment_create(request, pk):
if request.method == 'POST':
post = get_object_or_404(Post, pk=pk)
content = request.POST.get('content')
com_user = request.user
if not content:
messages.info(request, 'Write please')
return redirect('post_detail', pk)
Comment.objects.create(post=post, comment_user=com_user, comment_content=content)
return redirect('post_detatil', pk)
Note that typically retrieving and validating data is done through a Form, not by the view itself.
