> ℹ Discourse now features a `/hot` topic list in core that can be added to your `top menu`
Repository: [GitHub - danskdynamit/discourse-hot-topics · GitHub](https://github.com/danskdynamit/discourse-hot-topics)
This plugin creates a “Hot” sorting criteria and builds a custom topic list based on the result of the following formula:
`likes / ((hours since creation + 2) ^ gravity)`
Things to note:
- The default gravity multiplier is 1.5 but you can adjust this in the settings for the plugin.
- You can add “hot” to the list of menu items to make it easier to access.
- There is also the option to add `?order=hot` to a URL to create your own links.
- Once enabled, the hot rating is recalculated every 30 minutes so it will take a bit of time to take effect at first. If you want to accelerate this, you can log in to Sidekiq and manually trigger the `HotRating` job.
This work was graciously sponsored by @commonpawn and @Oskar. Kudos to them for making this happen.
The following topics lend more background to why this exists:

[We would like](https://meta.discourse.org/t/dansk-dynamit-website-running-on-discourse/43430) to use a sorting criteria as [Hacker News](https://news.ycombinator.com/) to make sure we’re always serving the most popular content to our users. We’re imagining using a similar algorithm to the one used on Hacker News. Basically it should sort all topics on our forum on the front-page after this criteria - so you can keep scrolling forever.

So we’ve put that on ice for now. So the plan for our site is to use plugin, [Topic Previews](https://meta.discourse.org/t/topic-list-previews/41630), to display a like button on the front-page and we’re currently working with @joebuhlig on building a ‘[hot topics page](https://meta.discourse.org/t/wanted-hot-sorting-criteria-for-front-page/47136)’ which is using a similar algorithm as Hackernews to sort topics. It should be done very soon and released on Github when ready. Below how we plan to imp…

Yes.
Go to the category page you want and then select Hot from the menu. The URL will look similar to this: `yourdomain.com/c/CATEGORY/l/hot`.

Hello @joebuhlig,
Is it possible to change the frequence of the HotRating job in sidekiq ?

Give this a try:
[https://github.com/danskdynamit/discourse-hot-topics/commit/c13c1a6857146d532be4c124c0841791243b424c](https://github.com/danskdynamit/discourse-hot-topics/commit/c13c1a6857146d532be4c124c0841791243b424c)
It adds a setting `hot_topics_calc_period` that lets you set the period (in minutes). Note that you’ll need to do a rebuild every time this setting is changed before it will take effect.

Hello Joe,
Is the “staff like weight” parameter is taken into account in the hot topic plugin ?
This option is in the parameters “other” tab.

Currently, it is not.

Hello @joebuhlig,
After some tests, i’m pretty sure that replies likes, are taken into account in the formula. I think it’ll be better and more logical, to only takes likes of the first post.
Don’t you think ?

Yes. It does count likes on all posts. It’s beyond me on whether or not that’s a good way to do it. The formula is a copy from other models. @commonpawn and @Oskar, do either of you have a strong leaning here?

@joebuhlig if you have a bit time and if @commonpawn and @Oskar are ok, i can sponsorize this job, to add an option to take or not in account replies likes.

Sometimes things work out really quick. Thanks to @kam44 for making this happen.
You can now choose to use only the likes on the original post in the calculation as opposed to likes across all replies.

The plugin works well, but does it do the “x new posts. Click to refresh” live updating that is done on the core lists? It would be nice if it could (not so much to change the order of the posts, but to notify the users as to which posts have replies…)

I’m getting a 500 (`/hot` route) error after installing it and I’ve run the HotRating job, I’m missing something?

Regarding this:

> As it stands, the Top view doesn’t actually work, since it’s still based on Likes and other metrics. To avoid confusion, it’d probably be best if a voting-category excluded Top entirely, and instead showed “Most voted”, simply showing the most voted ideas in descending order, like on UserVoice.
Do you think Hot Topics could be made to support Feature Voting as well? Or would it be easier if Feature Voting just comes with its own concept of “Hot” sorting?

I see no reason for a cascade of dependency, feature voting can take care of itself

使用此插件时遇到了错误。
我将插件添加到 Discourse 的 plugins 文件夹，然后使用 `bundle exec rails server` 启动 Rails 服务器，结果遇到了这个错误。只有这个插件出现了此类错误。

我是 Discourse 的新手，也许我犯了一些致命错误？还是其他人也遇到了同样的问题？
我使用的是 Ruby 2.6.1 和 Rails 6.0.0，以及来自 GitHub 的最新版本的 Discourse。

更改
> class HotRating \< Jobs::Scheduled
为
> class HotRating \< Scheduled
这对我有效。我认为问题出现的原因是该类已经封装在模块 `::Jobs` 中，因此我们无需再次指定该模块。
