Django blog post_update function not working as intended - django

Question

I am following a youtube channel to create a blog. I am stuck at post_update function. when i try to update the post the comment is getting updated, which should not happen in this scenario. where am I going wrong?
def post_update(request, id):
title = 'Update'
post = get_object_or_404(Post, id=id)
form = PostForm(
request.POST or None,
request.FILES or None,
instance=post)
author = get_author(request.user)
if request.method == "POST":
if form.is_valid():
form.instance.author = author
form.save()
return redirect(reverse("post-detail", kwargs={
'id': form.instance.id
}))
context = {
'title': title,
'form': form
}
return render(request, "post_create.html", context)

Whatever is present in content is getting updated as comment which should not happen I am not able to understand the flow. And also <P> tag is visible which I have not used in html.
