Soft-delete and restore rows
Problem
Deleting a record should be reversible and keep audit history.
Mark the model #[rustango(soft_delete)]. Deletes set a timestamp instead of removing the row; the default manager hides trashed rows automatically.
post.soft_delete(&pool).await?; // hidden from Post::objects()
post.restore(&pool).await?; // back in the active set
let trashed = Post::objects().trashed().fetch(&pool).await?;
Post::objects().purge_older_than(days(30), &pool).await?; // hard-delete old
