Solved Problem configuring plugin

[dude]

Hi all

Hi all, new cloudron user here (self hosted)

I went to Discourse forum to get help regarding their RSS Polling Plugin at https://meta.discourse.org/t/configure-the-discourse-rss-polling-plugin/156387/42?u=dude

But they say they do not give support to Cloudron hosted Discourse forums, so seems I have no other option than to try to get help from fellow cloudron users.

I am on latest cloudron, and Discours 2.6.2, running on DO droplet

Installing and activating the RSS Polling plugin seems to work well, but when I try to add a feed by clicking on the + icon, nothing happens (inputfields to edit do not open/do not show up) and I get this error message.

In Chromium it look like this:

Anyone have any idea what might be the problem, and how to solve it? I have tried three different browsers, disabled adblock, tracking protection, everything I can think of…refreshed, cleaned cache, still not working.

Plugin author says all work as intended when plugin is installed on a Discourse instance that is installed the supported way (not cloudron): https://meta.discourse.org/t/configure-the-discourse-rss-polling-plugin/156387/52?u=dude

So, anyone here able to help?

@dude if it works outside cloudron, it should work in cloudron as well. Let me test and get back.

@dude I could reproduce your problem, I will take a closer look tomorrow.

@girish Thank you

I am a bit amazed at the folks over at Discourse. They have actually deleted my above linked requests for support. Just hope some of you managed to read them before they got deleted, so no one thinks I am making things up.

I got swamped by other support tickets today, so this bug lives another day.

@dude Just starting taking a look now and I think the issue is that the latest master branch of the plugin is supporting Discourse 2.7 whereas Cloudron is on 2.6.2. Indeed, the error message you have on the console matches the latest commit - https://github.com/discourse/discourse-rss-polling/commit/fe176b4c1a8ccc7c8cc9fd3c9c56305e8dbb0d48 . The plugin author probably knew that but most likely got distracted by Cloudron installation

So, git reset to the previous commit - git reset --hard 45b174a3e5fb3bea07fa613412da4d3c9c2858bf and then rm -rf /run/discourse/public/assets/* and restart the app. It seems to work after that:

@girish thank you.

But I am not sure how to use that git command, where to use it, and in what order, any help?

@dude (btw this username confuses me hella lot )
From following the docs for Discourse:

https://docs.cloudron.io/apps/discourse/

cd /app/code/plugins
git clone <plugin-repo>
cd /app/code
bundle exec rake plugin:install_gems['REPLACE_WITH_PLUGINS_NAME'] 

# the line below will force assets to be rebuilt on next application restart
rm -rf /run/discourse/public/assets/*

This tells me I have to go into /app/code/plugins and clone my plugin.
In your case its:

https://github.com/discourse/discourse-rss-polling

so the command would be

cd /app/code/plugins
git clone https://github.com/discourse/discourse-rss-polling.git

This way the newest version is installed.

@girish figured out you need to downgrade to a specific commit

This would look like:

cd /app/code/plugins/discourse-rss-polling
git reset --hard 45b174a3e5fb3bea07fa613412da4d3c9c2858bf

This way git resets the current state master (freshly cloned) to the state of the commit ID 45b174a3e5fb3bea07fa613412da4d3c9c2858bf

After that rm -rf /run/discourse/public/assets/* and restart the app.

@brutalbirdie thanks a lot. I was not aware I had to navigate inside the discourse-rss-polling directory to issue the git reset
command. Tanks for helping

[dude]

I guess this thread can be marked as "solved".

Thanks for help, @girish and @BrutalBirdie
