Provide admin View so that columns like "last modified" can be added

Maybe using by default a view instead of a custom list builder would be more convenient, allowing users to fully customize the listing.

Agree with this idea.

I'll work on a view that provides the same functionality as the custom list builder.

This adds a view that provides the same functionality as the custom list builder. It also removes the list builder.

This broke a number of tests appears, also doesn't have coverage for the change itself.

I fixed the issue that caused the tests to fail.

My proposed change converts the custom list builder to a view with the same functionality (and it also removes the list builder).

So I actually did not create a Last Modified column as initially proposed in this issue. This column can be added now that the list is a view.

I added a test for the list (view) mainly focusing on the custom views fields.

Pinged the main Mainer but some feedback

This will need to target 3.1.x
Annotations should be replaced with attributes
Don’t think we need text claiming AI generated but good to announce it here
I’m not 100% we should delete the view builder. Pretty sure node for example if views isn’t installed falls back to a view builder.

Pushed up some changes I mentioned in #12

@batigolix thoughts?

I think this indeed the best approach. It allows users to customize the list (as requested in this issue) if they have Views enabled. I will edit the issue description so that it reflects the latest changes.

I rephrased the documentation a bit so that it is clear that the view is optional.

I tested this manually: without views /admin/content/sitewide_alert shows the custom list. After enabling views, /admin/content/sitewide_alert shows a view. I can also add a column "Changed"

This can be reviewed by others.

All feedback for this one has been addressed.

Goofed and merged to 3.0.x vs 3.1.x, reverted that and pushing to 3.1.x will merge once green.

This adds a view in config storage with no UUID

Steps:

Updated the project to 3.1.0.
Ran drush updb -y
Exported the config. I can see views.view.sitewide_alert_admin.yml has been created but lacks uuid

When I install the site from config, I'm getting:

> [2026-03-23T12:41:40.393803+01:00] php.WARNING: Warning: Undefined array key "uuid" in Drupal\Core\Config\StorageComparer->addChangelistUpdate() (line 303 of /var/www/html/web/core/lib/Drupal/Core/Config/StorageComparer.php)

...

I've tried to add a fix but it seems the function in only in 3.1.0 but not in 3.1.x. Weird EDIT: It was an outdated branch

Opened https://git.drupalcode.org/project/sitewide_alert/-/merge_requests/103 which fixes the issue. I cannot set to "Needs review" could you check and do a new release? Thank you
