以yii2形式获取多个表中的值数据

Question

我的项目有问题。在问之前，我想为你解释一下具体我的数据库和我的逻辑程序。

我有 3 个表，这些表是 anak_asuh（主键 kode_anak_asuh，外键 kode_calon）、calon（主键 kode_calon）和 perkembangan（主键 tanggal，外键 kode_anak_asuh）。 calon 与 anak_asuh 的关系是一对一的，而关系表 anak_asuh 与 perkembangan 的关系是一对多的。

然后我创建了用于保存在 perkembangan 表中的表单。但是当我使用下拉列表在表 calon 中获取名称 calon 值时，我遇到了问题。

问题是如何通过一张表获取价值数据？ 详细说明我的问题是当我在表 calon 中获得值名称 calon 时，但在它通过表 anak_asuh 之前。我做不到，请举个例子。

在视图中：

<?php

use yii\helpers\Html;
use yii\bootstrap\ActiveForm;
use yii\widgets\Pjax;
use yii\bootstrap\Modal;
use yii\helpers\Url;

use kartik\widgets\DatePicker;

$this->title = 'Form Perkembangan Anak Asuh';

?>

<h1 align="center">Entry Perkembangan Anak Asuh</h2>

<?php $form = ActiveForm::begin([

    </div>
</div>

</table>

</div>

</div> <!-- /panel -->

</div> <!-- /container -->

<?php ActiveForm::end();?>

<?php
$script = <<< JS
$('input#calon-alamat').change(function() {
        var kodeId = $(this).val();
        $.get('get-calon', { kodeId : kodeId }, function(data) {
            var data = $.parseJSON(data);
            $('#calon-nama_calon').attr('value',data.nama_calon);
        });

你也可以发布模型和搜索模型，因为连接和关系可以只在模型中而不是在控制器中完成。也许你可以看看here。在此链接中，您将看到相关表格中的数据传递是如何完成的，因此也许您可以进行一些小的更改并在您的应用程序中使用它。我有一个基于这种方式的依赖下拉列表，并且能够在客户设置应用条件后传递所有数据。
