Php GridView中相关模型的过滤器设置
我试图在Yii2的小部件中为相关模型设置过滤器,但我不断得到错误,比如过滤器值必须是整数 我跟着。现在,我有两个模型Php GridView中相关模型的过滤器设置,php,gridview,yii,yii2,Php,Gridview,Yii,Yii2,我试图在Yii2的小部件中为相关模型设置过滤器,但我不断得到错误,比如过滤器值必须是整数 我跟着。现在,我有两个模型Services.php和ServiceCharge.php 在ServiceCharge.php中,关系设置如下: public function getServiceName() { return $this->hasOne(Services::className(),['id'=>'service_name']); } 在Serv
Services.php
和ServiceCharge.php
在ServiceCharge.php
中,关系设置如下:
public function getServiceName()
{
return $this->hasOne(Services::className(),['id'=>'service_name']);
}
在ServiceChargeSearch.php
中,代码如下:
<?php
namespace app\models;
use Yii;
use yii\base\Model;
use yii\data\ActiveDataProvider;
use app\models\ServiceCharges;
/**
* ServiceChargesSearch represents the model behind the search form about `app\models\ServiceCharges`.
*/
class ServiceChargesSearch extends ServiceCharges
{
/**
* @inheritdoc
*/
public function attributes()
{
// add related fields to searchable attributes
return array_merge(parent::attributes(), ['serviceName.services']);
}
public function rules()
{
return [
[['id'], 'integer'],
[['charges_cash', 'charges_cashless'], 'number'],
[['id', 'serviceName.services', 'room_category'], 'safe'],
];
}
/**
* @inheritdoc
*/
public function scenarios()
{
// bypass scenarios() implementation in the parent class
return Model::scenarios();
}
/**
* Creates data provider instance with search query applied
*
* @param array $params
*
* @return ActiveDataProvider
*/
public function search($params)
{
$query = ServiceCharges::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$dataProvider->sort->attributes['serviceName.services'] = [
'asc' => ['serviceName.services' => SORT_ASC],
'desc' => ['serviceName.services' => SORT_DESC],
];
$query->joinWith(['serviceName']);
$this->load($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;
}
$query->andFilterWhere([
'id' => $this->id,
// 'service_name' => $this->service_name,
'room_category' => $this->room_category,
'charges_cash' => $this->charges_cash,
'charges_cashless' => $this->charges_cashless,
])
->andFilterWhere(['LIKE', 'serviceName.services', $this->getAttribute('serviceName.services')]);
return $dataProvider;
}
}
[
'attribute'=>'service_name',
'value'=>'serviceName.services',
],
正确显示相关模型中的服务名称
我看不出我做错了什么,但是服务属性的过滤器字段根本没有显示出来。实际上它比看起来简单得多
列\u name
添加到安全属性。
注意:这应该是关系名称$query->joinWith(['serviceName','roomCategory')添加连接代码>
->andFilterWhere(['like', 'services.services', $this->service_name])
->andFilterWhere(['like', 'room_category.room_category', $this->room_category]);
$dataProvider->sort->attributes['service_name'] = [
'asc' => ['services.services' => SORT_ASC],
'desc' => ['services.services' => SORT_DESC],
];
$dataProvider->sort->attributes['room_category'] = [
'asc' => ['room_category.room_category' => SORT_ASC],
'desc' => ['room_category.room_category' => SORT_DESC],
];
public$roomCategory
就这样。对相关表的排序和筛选都可以完美地工作
注意:删除相关列的默认验证,如整数和由gii
生成的默认筛选,否则将生成错误
最新版本更新:
- 不需要添加Public$属性李>
- 也不需要为关系添加安全属性
- 但是当前模型中需要筛选的属性是 添加到必须的安全属性
- 最重要的是,在gridview中,相关属性必须 以闭包形式
[
'attribute=>'attribute_name',
'value=function($data){
return $data->relationname->related_table_attribute_name
}
],
请记住,您使用的是
关系\u名称。相关的\u表\u属性\u名称过滤器在某种程度上对我不起作用。有一套相当全面的说明。唯一需要注意的是,搜索模型抱怨以下几行内容,但如果没有它们,一切似乎都能正常工作:
$this->addCondition(...);
对于模型PaymentEvent(表:subs_payment_event),其货币id字段链接到模型货币,这是完整的附加代码集(使用基本模板):
在主模型PaymentEvent.php中:
public function getCurrencyName()
{
return $this->currency->name;
}
在搜索模型PaymentEventSearch.php中:
public $currencyName;
在其规则中:
[['currencyName'], 'safe'],
在其setSort语句的属性中,包括:
'currencyName' => [
'asc' => ['subs_currency.name' => SORT_ASC],
'desc' => ['subs_currency.name' => SORT_DESC],
'label' => 'Currency'
],
在网格过滤条件之前:
$query->joinWith(['currency' => function ($q) {
$q->where('subs_currency.name LIKE "%' . $this->currencyName . '%"');
}]);
最后,在视图中的GridView列数组中(包括我通常指向相关模型记录的链接):
你可以把完整的php代码发布在“ServiceChargeSearch.php”中吗。错误是由于验证程序已配置incorrectly@BalajiViswanath-更新并添加了serviceChargeSearch.php的完整代码
[
'attribute' => 'currencyName',
'label' => 'Currency',
'format' => 'raw',
'value' => function ($data) {
return Html::a($data->currency->name, ['/currency/' . $data->currency_id]);
},
],
