Codeigniter Datamapper 按关系排序
下午好，
我正在使用 Datamapper Overzealous Edition for Codeigniter 构建一个足球联赛网站。我的所有赛程表都存储在具有以下格式的数据库表中：
ID Competition_id Home_team_id Away_team_id Etc...
正如您所猜测的，我的比赛表具有以下格式：
ID Name
当我从数据库中获取赛程表时，我想按相关比赛名称对它们进行排序，例如，我会使用以下内容：
$fixtures = new fixtures();
$fixtures->order_by('competition/name','asc')->get();
不幸的是，order_by 函数似乎不支持这种形式的语法。有人能想出一个干净的方法来完成这个任务吗？我能想到的就是手动将每个灯具放入数组中并以这种方式排序，但这似乎有很多冗余代码！
非常感谢。

Good afternoon,
I am using Datamapper Overzealous Edition for Codeigniter to build a football league website. All of my fixtures are stored within a database table with the following format:
ID Competition_id Home_team_id Away_team_id Etc...
As you guessed, my competitions table has the following format:
ID Name
When I get my fixtures from the database, I would like to order them by the related competitions name so for example, I would use the following:
$fixtures = new fixtures();
$fixtures->order_by('competition/name','asc')->get();
Unfortunately, it seems that the order_by function does not support this form of syntax. Can anybody come up with a clean way to accomplish this? All I can think of is manually placing every fixture into an array and ordering that way but that would seem like alot of redundant code!
Many thanks in advance.
Dan

我相信您必须加入表格并按所需字段进行排序。
I believe you have to join the table and sort on the field needed.
