锂的独特选择 [英] distinct selects in lithium

问题描述

使用锂模型，如何实现从MongoDB的集合中获得特定字段的不同结果集?

Using Lithiums Model, how do you achieve getting a distinct result set of specific fields from a collection in MongoDB?

mongo查询:

db.blogs.distinct('url');

推荐答案

据我所知，目前还没有一种优雅的方法.您可以直接使用 Pecl MongoDB 对象来获得结果. command功能允许您拨打所需的任何电话.

There currently isn't a way to do this elegantly to my knowledge. You can get results by working with the Pecl MongoDB object directly. The command function allows you to make any call you want.

$db = Connections::get('default');
$blogs = $db->connection->command(array('distinct'=>'blogs', 'key'=>'url'));
