In Post_blog you have return get_details(request,blog_id=post.id) . This calls get_details with POST request and create new comment. You should change it to return redirect('blog_get_detail') but dont forget to import redirect first:

from django.shortcuts import redirect
return redirect('blog_get_detail', post.id)
