【问题描述】：
我正在尝试为迷你地理定位系统制作搜索模型。每当我尝试通过直接调用 GeoData 模型对数据进行排序时，除非我们尝试排序，否则它会起作用。
但是当我们尝试使用 CustomMade SearchModel 时，它会发送： 为 foreach() 提供的参数无效
这是 SearchModel：
<?php namespace app\models;
use Yii;
use yii\base\Model;
use yii\data\ActiveDataProvider;
use app\models\GeoData;
/**
* This is the ActiveQuery class for [[GeoData]].
*
* @see GeoData
*/
class GeoDataSearch extends GeoData
{
const TODOS = 1;
const FECHA = 2;
const ENVIADO_POR = 3;
public function rules()
{
return [
[['latitude', 'longitude'], 'required'],
[['latitude', 'longitude', 'accuracy', 'speed', 'betterlocation'], 'number'],
[['device_id', 'active', 'sended', 'mobildate', 'created_at', 'updated_at', 'created_by'], 'integer'],
[['created_by'], 'exist', 'skipOnError' => true, 'targetClass' => User::class, 'targetAttribute' => ['created_by' => 'id']],
];
}
/*public function active()
{
return $this->andWhere('[[status]]=1');
}*/
public function scenarios()
{
return Model::scenarios();
}
public function search($params)
{
$query = GeoData::find()->where(['created_by' => $params])->all();
$dataProvider = new ActiveDataProvider([
'query' => $query,
'sort' => [
'defaultOrder' => [
'created_at' => SORT_DESC,
]
]
]);
$dataProvider->sort->attributes['created_at'] = [
'asc' => ['created_at' => SORT_ASC],
'desc' => ['created_at' => SORT_DESC]
];
$dataProvider->sort->attributes['created_by'] = [
'asc' => ['created_by' => SORT_ASC],
'desc' => ['created_by' => SORT_DESC]
];
$dataProvider->sort->attributes['geo_id'] = [
'asc' => ['geo_id' => SORT_ASC],
'desc' => ['geo_id' => SORT_DESC]
];
$this->load($params);
$query->andFilterWhere([
'geo_id' => $this->geo_id,
'latitude' => $this->latitude,
'longitude' => $this->longitude,
'accuracy' => $this->accuracy,
'speed' => $this->speed,
'device_id' => $this->device_id,
'betterlocation' => $this->betterlocation,
'active' => $this->active,
'mobiledate' => $this->mobildate,
'sended' => $this->sended,
'updated_at' => $this->updated_at,
'created_at' => $this->created_at,
'created_by' => $this->created_by,
]);
return $dataProvider;
}
}
控制器（注释的代码有效，但不允许我使用 GridView 也不允许过滤或排序：
public function actionView($id)
{
$title = "Ver Historial";
$id = $_GET['id'];
$searchModel = new GeoDataSearch;
$dataProvider = $searchModel->search($id);
return $this->render(
'view',
[
'title' => $title,
'searchModel' => $searchModel,
'dataProvider' => $dataProvider
]);
/*
if (Yii::$app->user->can(AuthItem::ROLE_ADMINISTRATOR))
{
$id = $_GET['id'];
$title = "Ver Historial";
$model = new GeoData;
$dataProvider = $model::findAll(['created_by'=> $id]);
return $this->render(
'view',
[
'title' => $title,
'dataProvider' => $dataProvider,
]
);
} else {
throw new ForbiddenHttpException('Access denied for user '.Yii::$app->user->identity->id);
}
*/
}
任何建议将不胜感激！
【问题讨论】：
-
我认为您在搜索功能中使用参数是不正确的。 params 应该是一个 'attributes' => 'value' 对的数组。你应该相应地更新你的代码。
-
使用
ActiveDataProvider，您的$query不应调用all()，因为它不再是Query对象（它将是模型数组）。
