在yii2中执行“搜索”时显示的行没有任何更改。

Question

在使用yii2进行模型搜索时，我遇到了问题。这是关系图

​

​

我希望将Jurusan从表aitambah显示到表ais3，并将NamaMahasiswa从表aiE 210显示到E 111通道3E 212。我制作了s3penghubung表，以便表aitambah可以与ais3相关。我能展示它们。但是，当我尝试在Jurusan字段中键入"BIO“时，搜索无法正常工作。这是刷新页面。显示的行没有任何更改。那么，我该怎么做才能解决这个问题？

我不知道怎么修正那些密码。你能帮我解决这个问题吗？谢谢你

Answer 1

您的代码很难调试。尽量保持命名约定的一致性。Yii方式是用下划线分隔的小写字母。

请阅读有关显示和排序关系的这和这。

至于解决方案，您可以尝试以下几点：

在模型中创建一个新的关系：

/**
 * @return \yii\db\ActiveQuery
 */
public function getAitambah()
{
    return $this->hasOne(Aitambah::className(), ['NRP' => 'NRP']);
}

然后在你的SearchModel

public function rules()
{
    return [
        [['id', 'kode'], 'integer'],
        [['NRP', 'NRP1', 'NRP2', 'NRP3', 'NRP4', 'NRP5', 'NRP6', 'NRP7', 'namaMahasiswaText', 'ProgramStudi', 'TanggalMasuk', 'TanggalKeluar', 'jURUSANText','NAMKANTOR','ANGKATAN', 'JURUSAN'], 'safe'],
    ];
}

在你的搜索方法中：

...
$query = Ais3::find();
query->joinWith(['ai ai', 'aitambah aitambah']);
...

最后，在你看来：

[
    'attribute' => 'JURUSAN',
    'value' => 'aitambah.JURUSAN',
    'label' => 'JURUSAN',
],
