Using slug only as url without id

caiiiycuk · December 25, 2020, 6:01pm

Hi. I use slug only urls, like:
https://talks.dos.zone/t/007-james-bond-the-stealth-affair-1990-fr/
But if I open it directly in browser it redirects to welcome topic. When I click same url into another topic it works normally.
Example (click on French link):

Is it intended behavior?

This is working as intended.

Discourse support the 3 types:

Full: https://meta.discourse.org/t/using-slug-only-as-url-without-id/174258
Only ID: https://meta.discourse.org/t/174258
Only Slug: https://meta.discourse.org/t/using-slug-only-as-url-without-id

But if the slug starts with a number we special case and look for the first number as an ID:

github.com

discourse/discourse/blob/master/app/controllers/topics_controller.rb#L65-L70


# Special case: a slug with a number in front should look by slug first before looking
# up that particular number
if params[:id] && params[:id] =~ /^\d+[^\d\\]+$/
  topic = Topic.find_by_slug(params[:id])
  return redirect_to_correct_topic(topic, opts[:post_number]) if topic
end

Ahh ok. So it will affect little amount of urls. Thank you!

That’s more work than using the url in your browser (that has the ID) and will break if you rename the topic. (plus when the title starts with a number)
