Just pass actually ordered collection to collection_select helper:
只需将实际有序的集合传递给collection_select帮助器:
collection_select(:post, :author_id, Author.order('created_at DESC'), :id, :name_with_initial, :prompt => true)
So, in your source example it will look like this:
因此,在您的源示例中,它将如下所示:
<%= f.collection_select :player1, Player.order('plays DESC'), :id, :name %>
