Most Pelican themes pass article URL to Disqus as the Disqus identifier.
This puts you at a disadvantage. If you are forced to change URL of an article you will lose Disqus discussion for that article because Disqus identifier for the article will change too.
Elegant offers you comment_id property that you can set in your
article metadata. Set it to any unique string you want. It won’t be effected by
the article URL.
If you choose not to use comment_id, Elegant passes article URL to Disqus.
Legacy Variable
In previous versions, we had disqus_identifier. Though Elegant is backward compatible but we recommend you to change it to comment_id.
