ORDER 条件在 cakephp 3 TREE 行为中不起作用

Question

我正在为类别 table 使用 cakephp-3 树行为。这里 'sequence_no' 字段用于对类别的子类别列表进行排序。我正在使用 category_id 进行搜索，以按 'sequence_no' 的升序获取他的所有子类别。但是订单在这里不起作用。我的代码片段和输出在这里。

 $categoris = $this->Categories->find('children', ['for' => $id])
            ->find('threaded')
            ->contain('ParentCategories')
            ->order(['Categories.sequence_no' => 'ASC'])
            ->toArray();

- 输出样本：

}

Answer 1

由于 findChildred 查找器在您的查询中添加了一个 ORDER lft asc 子句，您的订单条件将附加到该子句中

如果您想强制执行订单，您可以这样做

->order(['Categories.sequence_no' => 'ASC'], true)

order()方法中的第二个参数告诉cake覆盖之前设置的ORDER BY
