本文实例讲述了Yii2实现让关联字段支持搜索功能的方法。分享给大家供大家参考,具体如下:
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:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22

<?= 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:
1
2
3
4
5
6
7
|
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:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25

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 ; |
