plugins with assets are not installed properly

[Jay Kuri]

Summary: When the plugins config option is used, the charm fetches the plugin onto the server(s) but if the plugin has assets, they will not become available.

What I did:

juju config discourse plugins="https://github.com/canonical-webteam/discourse-markdown-note.git"

What I expected:

The discourse-markdown-note plugin would become usable once the config action finished running.

What happened instead:

The plugin was installed on the discourse unit, but the resources (js and css) were not available to users.

Workaround:

After the config hooks finished, I ran the following commands on the discourse unit (in the /srv/discourse/current/ directory)

RAILS_ENV=production bundle install
RAILS_ENV=production bundle exec rake db:migrate
RAILS_ENV=production bundle exec rake assets:precompile

And then restarted the discourse unicorn server via systemctl.

Everything Jay ran by hand is part of the prepare_codebase reaction in the charm, we may just want to add a reaction to call that when plugins change.

[Jay Kuri (jk0ne)]

David is correct. The issue is that the plugin are loaded after these steps are run. To fix this bug, the code needs to be adjusted to download the plugins first, then do rhe bundle steps.
