Add a custom admin bulk action
Problem
Editors need a one-click "Publish selected" button in the admin list view.
Register a bulk action; it receives the selected primary keys and runs your closure inside a transaction.
register_admin_action!(Article, "publish", "Publish selected", |pool, ids| async move {
Article::objects()
.filter(Article::id.is_in(ids))
.update_pool(&pool, &[("status", "published")])
.await?;
Ok(())
});Permissions
Actions respect the same per-model permission codenames the admin uses — only users with article.change see the button.
