Django AJAX delete object in deleteView - django

Question

Good day.
I'm trying to understand how to use ajax by deleting a object.
Main problem, i don't understand how to pass slug argument to url in AJAX call.
path('posts/<slug:slug>/delete/', DeletePost.as_view(), name='delete_post')
class DeletePost(CsrfExemptMixin, DeleteView):
queryset = Post.objects.all()
def get_object(self, queryset=None):
obj = super(DeletePost, self).get_object()
profile = Profile.objects.get(user_id__exact=self.request.user.id)
if obj.profile_id != profile.id:
raise Http404
return obj
def delete(self, request, *args, **kwargs):
self.get_object().delete()
payload = {'delete': 'ok'}
return JsonResponse(payload)
What i also want to understand, is the functionality correct? I've tested without json and get_object returns the correct object.
{% for post in user_posts %}
<tr id="post_table">
<th scope="row">
<input type="checkbox" aria-label="Checkbox" style="display: none">
</th>
<td class="tm-product-name">{{ post.title }}</td>
<td class="text-center">145</td>
<td class="text-center">{{ post.total_likes }}</td>
<td>{{ post.created_at }}</td>
<td><button class="delete-icon" onclick='deletePost({{ post.slug }})'>btn</button></td>
{#<td><i class="fas fa-trash-alt tm-trash-icon delete-icon" id="{{ post.id }}"></i></td>#}
<td>
{#<form method="post" action="{% url 'post:delete_post' post.slug %}" id="delete">#}
{#{% csrf_token %}#}
{#<i class="fas fa-trash-alt tm-trash-icon"></i>#}
{#</form>#}
</td>
</tr>
{% endfor %}
<script>
function deletePost(slug) {
let action = confirm('Are you sure you want to delete this post?');
if (action !== false) {
$.ajax({
method: 'POST',
url: '{% url 'post:delete_post'%}',
success: function (data) {
if (data.delete()) {
$('#post_table').remove()
}
}
});
}
}
</script>
Obviously this is the error that i currently have.
Reverse for 'delete_post' with no arguments not found. 1 pattern(s) tried: ['posts/(?P<slug>[-a-zA-Z0-9_]+)/delete/$']
Technically i just need a ping to the correct DeleteView url with a correct slug, is there a need to parse json in the DeleteView ?

Anyway found a solution.
Changed my view to
class DeletePost(CsrfExemptMixin, SingleObjectMixin, View):
model = Post
def post(self, *args, **kwargs):
self.object = self.get_object()
self.object.delete()
data = {'success': 'OK'}
return JsonResponse(data)
and modified the ajax request
var slug = document.getElementById('delete-icon').getAttribute('data-id');
function deletePost() {
let action = confirm('Are you sure you want to delete this post?');
let url = '/posts/' + slug + '/delete/';
if (action != false) {
$.ajax({
method: 'POST',
url: url,
dataType: 'json',
success: function (data) {
$('#post_table').remove()
}
});
}
}
