Yii 框架中的模型？
我使用 Yii 框架构建一个网站应用程序。
我想将模型与查询一起使用，如下所示：
SELECT u.id, u.username, u.score, (SELECT COUNT(ownerId) FROM post p WHERE p.ownerId = u.id) AS totalPost
FROM users u
ORDER BY u.score DESC, totalPost DESC LIMIT 10
请帮助我将查询转换为 Yii Framework 中的模型。

Please help me to convert the query into models in Yii Framework.

这是《Yii 明确指南》的相关章节 - http://www.yiiframework .com/doc/guide/database.arr

好吧，我认为你可以通过使用关系 'TotalPost' => 来简化它array(self::STAT,'Post','OwnerId')
检查 CStatRelation 了解更多详细信息。请注意，在该类中，select 属性是统计表达式，默认为 COUNT(*)。
此外，只要您有一个公共 $TotalPost;，您的查询就可以映射到用户模型中。在模型类 User.
Well I think you can simplify this by using a relation 'TotalPost' => array(self::STAT,'Post','OwnerId')
Check CStatRelation for more details. Note that in this class, the select property is the statistical expression which is by default COUNT(*).
Also, your query can be mapped into User model as long as you have a public $TotalPost; in model class User.
