Question

我知道有一些与此相关的问题，但他们无法帮助我。

我已生成GridView，其中包含Sale模型，我添加了新列，该列来自不同的表，名为price。现在我想添加排序和过滤，但不知何故它不起作用..

以下是我正在做的事情：

第1步：将函数getItemPrice添加到Sale model：

中

/* Gets item price*/
public function getItemPrice()
{
    return $this->item->price;
}

第2步：在SaleSearch模型中定义价格规则：

/**
* SaleSearch represents the model behind the search form about `app\models\Sale`.
*/
class SaleSearch extends Sale
{
public $price;
/**
 * @inheritdoc
 */
public function rules()
{
    return [
        [['id', 'item_id', 'sign'], 'integer'],
        [['customer_name', 'customer_surname', 'customer_phone', 'customer_email', 'code', 'comment'], 'safe'],
        [['price'], 'double'],
    ];
}

第3步：将setSort()添加到同一模型中并打字joinWith语句：

public function search($params)
{
    $query = Sale::find();
    // add conditions that should always apply here

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

    $query->joinWith('item');
    $dataProvider->setSort([
        'attributes' => [
            'customer_name',
            'customer_surname',
            'customer_phone',
            'customer_email',
            'code',
            'comment',
            'sign',
            'price' => [
                'asc' =>['tbl_item.price' => SORT_ASC],
                'desc' =>['tbl_item.price' => SORT_DESC],
            ],
            'item_id' => [
                'asc' =>['item.name' => SORT_ASC],
                'desc' =>['item.name' => SORT_DESC],
            ]
        ]
    ]);

    $this->load($params);

    if (!$this->validate()) {
        // uncomment the following line if you do not want to return any records when validation fails
        // $query->where('0=1');
        return $dataProvider;
    }

    // grid filtering conditions
    $query->andFilterWhere([
        'id' => $this->id,
        'item_id' => $this->item_id,
        'sign' => $this->sign,
    ]);

    $query->andFilterWhere(['like', 'customer_name', $this->customer_name])
        ->andFilterWhere(['like', 'customer_surname', $this->customer_surname])
        ->andFilterWhere(['like', 'customer_phone', $this->customer_phone])
        ->andFilterWhere(['like', 'customer_email', $this->customer_email])
        ->andFilterWhere(['like', 'code', $this->code])
        ->andFilterWhere(['like', 'comment', $this->comment]);

    return $dataProvider;
}

}

我的GridView：

    <?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],

        [
            'attribute' => 'item_id',
            'value' => 'item.name',
        ],
        'code',
        'customer_name',
        'customer_surname',
        'customer_phone',
        [
            'attribute' => 'price',
            'value' => function($model) {
                return $model->item->price;
            },
        ],
        [
            'attribute' => 'sign',
            'value' => function ($model) {
                return $model->sign == 1 ? 'Apmokėtas' : 'Neapmokėtas';
            },
        ],

        // 'customer_email:email',
        //  'comment:ntext',

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

在编写这样的代码之后，我的所有GridView现在根本没有排序或过滤。有人能告诉我我做错了什么吗？

Answer 1

您使用代码覆盖Sort个对象。默认情况下，它会为所有属性准备排序。如果您只想添加一个字段进行排序，请执行以下操作：

$dataProvider->sort->attributes['price'] = [
        'asc' => ['tbl_item.price' => SORT_ASC],
        'desc' => ['tbl_item.price' => SORT_DESC],
        'label' => 'Item price'
    ];

这样您就不会覆盖默认行为。

Answer 2

您的属性名称为Kaina而不是price。所以，

$dataProvider->sort->attributes['Kaina'] = [
    'asc' => ['tbl_item.price' => SORT_ASC],
    'desc' => ['tbl_item.price' => SORT_DESC],
    'label' => 'Item price'
];

过滤和排序在Yii2中不起作用
