How to apply django lazy loading to load my comments? - django

Question

I am tried but i am not getting the desired output for lazy loading
views.py
def post_detail(request, pk):
post = get_object_or_404(Post, pk=pk)
content_type = ContentType.objects.get_for_model(Post)
obj_id = post.id
comments = Comment.objects.filter(
content_type=content_type, object_id=obj_id)
parent_id = request.POST.get("parent_id")
csubmit = False
if parent_id:
content_type = ContentType.objects.get_for_model(Comment)
Comment.objects.create(content_type=content_type,
object_id=parent_id,
parent_id=parent_id,
user=request.user,
text=request.POST.get("text"))
if request.method == 'POST':
form = CommentForm(data=request.POST)
if form.is_valid():
new_comment = form.save(commit=False)
new_comment.content_type = content_type
new_comment.user = request.user
new_comment.save()
csubmit = True
else:
form = CommentForm()
paginator = Paginator(comments, 10)
try:
comments = paginator.page(page)
except PageNotAnInteger:
comments = paginator.page(1)
except EmptyPage:
comments = paginator.page(paginator.num_pages)
return render(request, 'post_detail.html', {'post': post,
'comments': comments, 'csubmit': csubmit, 'form': form})
I want to apply lazy loading in the above view and want to apply on template.Above i added pagination and rendered in template
post_details.html
{%for comment in comments %}
<br>
{{comment.text}}<br/>
by {{comment.user}}<br>
<a href='#' class="rep_cmt" data-parentid="
{{comment.id}}">Reply</a><br>
{% for comment in comment.children.all %}
{{comment}}
{% endfor %}
{%endfor%}
{% if comments.has_next %}
<a class="infinite-more-link" href="?page={{ comments.next_page_number
}}">More</a>
{% endif %}
<div class="loading" style="display: none;">
Loading...
</div>
<script>
var infinite = new Waypoint.Infinite({
element: $('.rep_cmt')[0],
onBeforePageLoad: function () {
$('.loading').show();
},
onAfterPageLoad: function ($items) {
$('.loading').hide();
}
});
</script>
In above i added script to render data in lazy loading process but it is not rendering
