How can the user view the post, i.e. the value of last\_read\_post\_number is changed through which interface

You may need to elaborate a little more as I’m not sure your issue is properly explained.
(If you could also give your topic a more descriptive title that would be great 👍)

When the post is displayed in their browser it’s updated and, I think, posted back to Rails.
Is there a problem that you are trying to solve with the `last_read_post_number`?
