How to fix the same comments in Disqus?

Question

Django

On the backend:

this.page.url = '{{request.build_absolute_uri}}';
this.page.identifier = '{{post.id}}';

js output:

this.page.url = 'http://188.120.239.27:2228/news/post/1/';
this.page.identifier = '1'; // каждый раз меняется в зависимости от страницы

But it shows the same comments.
