查询时对相关模型的 Yii 限制

Yii limit on related model while querying(查询时对相关模型的 Yii 限制)

问题描述

我遇到了限制问题.我使用的代码如下:

I ran into limit problem. The code that I'm using is the following:

$model = PostCategory::model();
  $record = $model->with(array(
    'posts'=>array(
      'order'=>'posts.createTime DESC',
      'limit'=>3,
))->findByPK($id);

我想限制为分页目的查询的帖子.我也尝试添加

I want to limit the posts queried for paging purposes. I've also tried to add

'together'=>true

在限制之后，这也无济于事.

after limit, this doesn't help too.

感谢任何帮助.

推荐答案

这个肯定能用，刚刚测试过:

This will definitely work, just tested :

$model = PostCategory::model();
$record = $model->with(array(
  'posts'=>array(
     'order'=>'posts.createTime DESC',
  ))->findByPK($id,
             array('limit'=>3,'together'=>true) // adding this works
);
