Yii2让关联字段支持搜索功能

Yii2让关联字段支持搜索功能

这里有两张表，表结构如下,companies_compay_id 为外键

yii2advanced.branches表

branch_id:int(11)

companies_company_id:int(11)

branch_name:varchar(100)

branch_address:varchar(255)

branch_created_date:datetime

branch_status:enum('active','inactive')

yii2advanced.companies表

company_id:int(11)

company_name:varchar(100)

company_email:varchar(100)

company_address:varchar(255)

logo:varchar(200)

company_start_date:datetime

company_create_date:datetime

company_status:enum('active','inactive')

在上面表中，可以用companiesCompany.company_name来获取公司名，不过这样是不支持搜索的。

想要支持搜索功能，需要在branches的index视图添加以下代码

<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
//添加的代码开始
[
'label'=>'公司名',
'attribute'=>'companies_company_id',
'value'=>'companiesCompany.company_name'
],
//添加的代码结束
'companiesCompany.company_name',
// 'branch_id',
// 'companies_company_id',
'branch_name',
'branch_address',
'branch_created_date',
// 'branch_status',

['class' => 'yii\grid\ActionColumn'],
],
]); ?>

然后修改SearchBranches.php

修改rules方法为

public function rules()
{
return [
[['branch_id'], 'integer'],
[['branch_name', 'branch_address', 'branch_created_date', 'branch_status','companies_company_id'], 'safe'],
];
}

修改search方法

public function search($params)
{
$query = Branches::find();

$dataProvider = new ActiveDataProvider([
'query' => $query,
]);

$this->load($params);

if (!$this->validate()) {
// uncomment the following line if you do not want to any records when validation fails
// $query->where('0=1');
return $dataProvider;
}
// 添加下面这行代码
$query->joinWith('companiesCompany');
$query->andFilterWhere([
'branch_id' => $this->branch_id,
//    'companies_company_id' => $this->companies_company_id,
'branch_created_date' => $this->branch_created_date,
]);

$query->andFilterWhere(['like', 'branch_name', $this->branch_name])
->andFilterWhere(['like', 'branch_address', $this->branch_address])
->andFilterWhere(['like', 'branch_status', $this->branch_status])
// 添加下面这行代码
->andFilterWhere(['like', 'companies.company_name', $this->companies_company_id]);

return $dataProvider;
