Highest-Post Excerpts in Topic List

Customization Plugin

AI-generated summary

The Highest-Post Excerpts in Topic List plugin adds the most recent post excerpt to the topic list. dsims explains that it modifies the TopicListItemSerializer and requires the Latest Reply Excerpt theme-component for visibility. Dev_Singh encountered an installation error, mistaking the plugin for a theme. Moin clarified the correct installation process, and putty noted that plugin availability depends on the hosting plan. Dev_Singh confirmed that their Pro plan does not support custom plugins, preventing the installation of the theme component.

Features

Adds the excerpt from the topic’s most recent post (aka the post with the highest_post_number) to the TopicListItemSerializer.

Configuration

None for the plugin, but all the frontend UI related changes to actually see the excerpts are in a separate theme-component: Latest Reply Excerpt theme-component.

TODO

Limit to certain categories & tags?

I am getting an installation error:

An error occurred: Import Error: about.json does not exist, or is invalid. Are you sure this is a Discourse Theme?

You tried to install the Customization > Plugin as a Customization > Theme or Customization > Theme component. That doesn’t work. You need to follow Install plugins on a self-hosted site

Oh, I didn’t notice it was a plugin. However I am not on a self-hosted site. My site is hosted by Discourse. Is it possible to install this plugin on a Discourse hosted site? I am trying to get the theme component Latest-Post Excerpt installed which depends on this plugin.

It depends on your hosting plan. Most hosting tiers only allow a limited set of plugins, which are installed by default.

Like Moin said, you’ll have to check your plan. My community’s hosting plan is limited to official plugins, which this is not.

I am on the pro plan. There is no checkmark in the add-ons section for custom plugins on the plan detail page. I assume that means they are not allowed so I wont be able to install the Latest-Post Excerpt theme component. Thanks for pointing me in the right direction to find out how this works.
