Custom Wizard Plugin šŸ§™

Customization Plugin
958

I created a Custom Wizard and made several submissions as tests, and I canā€™t delete them manually. According to what I read in another thread, the only way is via Rails, but I canā€™t figure out which commands to use, ChatGPT fails a lot here.

Hi :slight_smile:
It looks like a very recent update to Discourse Core (over the June 6ā€“7 weekend) has introduced a breaking architectural change that causes the discourse-custom-wizard plugin to crash the entire application boot cycle.

Even attempting to visit /safe-mode fails with a global 500 error because the crash occurs during initialization middleware registration.

Here is the exact fatal error trace pulled from Logster:

ActionView::Template::Error (undefined method 'admin_stylesheets' for class DiscoursePluginRegistry)
lib/stylesheet/manager/builder.rb:199:in `Stylesheets::Manager::Builder#plugins_digest'

It appears that during the asset/stylesheet compilation phase (plugins_digest), core Discourse is invoking an admin_stylesheets method on the DiscoursePluginRegistry which is throwing an undefined method exception, likely due to a mismatch with how the custom wizard registers or extends administrative styles.

Disabling the plugin in app.yml and running a complete container rebuild allows the forum to boot normally, confirming the crash is isolated to the wizardā€™s integration hooks.

Could you please look into updating the registry/stylesheet hooks for compatibility with current core changes?

Thanks!

I can confirm the same error as well. Unfortunately, I had to suspend the plugin for the time being.

Thanks for the support.

Iā€™ve encountered an issue since updating to the latest version of Discourse and the plugin.

I have a field set up for users to select tags. Iā€™ve restricted the tags to a tag group, and selected the group in the Tag Groups section.

This used to work fine - users could only select from tags within that tag group.

Now, though, itā€™s as if the tag group doesnā€™t exist, and users are able to select any tag.

I tried to remove the tag group, save, and add it back, and that didnā€™t work. I also tried not using a tag group at all, and selecting the tags in the Content section, but thatā€™s limited to 5 tags and I have more than that.

Not sure what to do - this is completely breaking a workflow with my form. Iā€™m only using this option as a workaround since multi-select in a dropdown is not an option. Users can only select up to 3 options, so a group of checkboxes doesnā€™t really work either.

Any thoughts on a different workaround or whether I might be messing up somehow?
