I cannot go to the page I want - html

Question

Hello I have a post blog where I have a homepage with posts and if you click on it you are redirected to the post_detail page. Now I want the users to allow to delete their comments which I achieved but I want them to stay on the same post_detail page. I could not come over it and hope that someone can help me. Thanks in advance.
post_detail.html
<div class="container">
<br>
<h1 style="text-align:center;">{{post.post}} </h1>
<p style="font-size:small;text-align:center;">{{post.created_on}}</p>
<button type="button" class="btn btn-secondary float-right" data-toggle="modal" data-target="#exampleModal" data-whatever="#mdo">Yorum At</button>
<br>
<br>
<br>
{% for i in commentmodel_list%}
<h4 >{{i.comment}}</h4>
{% if i.author_security == user%}
<a style="float:right;color:red;"href="{% url 'forum:delete' slug=post.slug comment_id=i.id %}"><i class="fas fa-minus-circle"></i></a>
{% endif %}
{% if i.author is none %}
<p style="font-size:small;">Anonim | {{i.created_on}}</p>
{% else%}
<p style="font-size:small;"><a style="text-decoration:none;" href="#">#{{i.author}}</a> | {{i.created_on}}</p>
{% endif %}
<hr>
<br>
{% endfor %}
</div>

I would highly recommend to delete the comments via submitting a POST request with CSRF token, otherwise it's prone to CSRF attack. When you'll be submitting the form, you can add there an input with a value representing the current page which you'll redirect to afterwards. Pseudocode:
<form action="{% url 'forum:delete' slug=post.slug comment_id=i.id %}"
method="POST">
{% csrf_token %}
<input type="hidden" name="current_post" value="{{ post.slug }}">
<input type="submit>
</form>
view:
def delete_post(request, comment_id=None):
Comment.objects.filter(id=comment_id).delete()
return redirect('forum:post_detail', slug= request.POST['current_post'])
It's not obvious if by "I want them to stay on the same post_detail page" you mean that you dont want to perform the redirect in browser and you'd rather delete it via ajax. If that's the case, please check the Django documentation about AJAX request with CSRF, as there's an example how to do exactly that.
