Discourse Upgrade Breaks Categories.json

Support

AI-generated summary

Magnetidog encountered an issue with Discourse’s categories.json after upgrading to the latest build. The error message ActiveRecord::StatementInvalid (PG::UndefinedColumn: ERROR: column categories.suppress_from_latest does not exist was reported. codinghorror suggested rebuilding, but this did not resolve the issue. supermathie pointed out that the suppress_from_latest column was recently dropped and suggested checking plugin code for the error.

After further investigation, Magnetidog discovered that the official Discourse sidebar plugin was causing the issue. However, it was later revealed that the plugin was not developed by Discourse and had not been updated in 2 years. Magnetidog forked the plugin and fixed the issue, but suggested that the problematic code could be removed altogether.

Gulshan_Kumar attempted to install the Dynamic Sidebar plugin, but encountered an error. codinghorror advised scrolling up to look for earlier error messages to diagnose the problem.

Hello,

we just upgraded to the latest build from a recent version (around 1 week ago), and our website is currently down. Categories.json is not loading, and this is the error we see in the logs:

ActiveRecord::StatementInvalid (PG::UndefinedColumn: ERROR: column categories.suppress_from_latest does not exist

What can we do?

Thanks.

2

Try rebuilding again and see if that helps.

3

This column was dropped recently, so check to see if this error was raised in plugin code.

A more complete backtrace should show this information.

Rebuild apparently did not help!

This is the full error.

From the backtrace it looks like it might be the sidebar plugin - checking it-.

Hello!

It is the official discourse sidebar plugin causing this, disabling it fixes the issue. Here is the backtrace again

Can you link me to the plugin, are you sure it has the official tag?

Hello Sam,

I thought it was the official one because it was under the discourse/ repository, but it looks like it was not developed by you guys (and not updated in 2 years). You just ported it to Ember 2.

https://github.com/discourse/plugin_discourse_dynamic_sidebar

The issue is in plugin.rb, where I think they use that field for some feature(generation of a cached html block, latest_solved_answers) that is actually not implemented in the sidebar functionality itself. I forked and fixed the issue, but I think you can just remove all that code to do what the script is supposed to do (adding a simple sidebar space on the side).

And this is my fork, but use with caution as it fixed the issue for me but I have not yet tried if that generated html block works.
