Follow up: Assign Plugin Conflict

Support
1

Previously we ran into issues with upgrading to the latest version of Discourse, this turned out to be related to the Assign Plugin/ Production Data issue that @angus helped us identity and resolve by removing the plugin.

Moving forward we would like to reinstate the plugin but need to eliminate the chance of encountering the game breaking error we experienced previously. Below is details related to the log excerpts when everything was going on.

Sorry, I am not following? Conflict with what?

Are you sure “group id 3 admins” is correct?

https://github.com/discourse/discourse/blob/master/app/models/group.rb#L66-L76

@Mittineague I confirmed this morning that the group id for admins is indeed the default group ID.

05%20AM

The log information I included was during our down time and we have temporarily removed the Assign plugin which immediately resolved the issue and allowed us to successfully leverage discourse again.

6

The value of the assign_allowed_on_groups site setting is in a bad state. We migrated from using group names to group IDs.

(groups.id in (‘3’,‘admins’,’…

admins should be replaced with the group ID to fix the issue.

How do I go about modifying that?

From your Discourse folder, you should:

  • Enter the container running ./launcher enter app
  • Open a Rails console running rails c

Once inside the console, you can run this script to fix the issue:

allowed_groups = SiteSetting.assign_allowed_on_groups.split('|')
allowed_groups.map! do |ag| 
  ag.to_i.to_s == ag ? ag : Group.select(:id).find_by(name: ag).id
end

SiteSetting.assign_allowed_on_groups = allowed_groups.join('|')

After doing the above suggested, I was not able to successfully run the script. Below is the output of the attempt. Any direction is highly appreciated :pray:

app:/var/www/discourse# rails c

Looks to me like you have an old version of Discourse assign installed … are you on tests-passed with latest discourse assign?

Let me look into this @sam and I will let you know what I find :+1:

12

With the Assign Plugin currently removed @sam, you feel reinstalling the plugin with the latest version might be the best course of action?

13

@sam @angus I went to reinstall the Assign plugin again tonight and experience complete failure again after sign in. I captured logs of the failure but wouldn’t prefer not to post them publicly but willing to do so via DM.

Any suggestion on how to move forward?

14

Are you on the stable branch? Are there other plugins you have installed that might be causing a conflict?

15

I believe so as I pulled from Master.

Just the following, nothing that would stick out to me.

You’d need to have done some work to be on the (less desirable) stable branch. Do you see something like

version: stable

in your app.yml? If you’re on stable then things might be more complicated.

You might try ./discourse-doctor. And/or make sure that you do a git pull before rebuilding.

Any additional ideas here to help us move forward with the Assign plugin? @angus?

Hey @Jim.Morrison ,

Can you run this inside a console and show me the output:

DB.query_single(<<~SQL SELECT site_settings.value FROM site_settings WHERE site_settings.name = 'assign_allowed_on_groups' SQL ).first.to_s.split('|')

I believe that my script didn’t work because the plugin was disabled.

Direct messaged you the details from the console. Thanks @Roman_Rizzi!

After going back and forth with @Roman_Rizzi on this, we were able to finally get this resolved!

After running the query that Roman wrote to eliminate a data conflict, adding the Assign plugin and then rebuilding the app, I was met with success!

Roman has been a huge asset through this whole ordeal and I couldn’t give him enough praise for this! Thank you so much for working with me on this @Roman_Rizzi!
