Question

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

mongo query:

db.blogs.distinct('url');

Answer 1

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'));
