运行Yii2 kartik Export Extension时出现问题

标签: php widget yii2 yii-extensions

我是Yii的新手,我正在开发一个从MySQL读取表格的数据库应用程序。我需要用户能够以CSV或PDF格式导出数据,因此我下载了Kartik Yii2 Export Extension。我不知道如何配置我的设置来运行此扩展,我阅读了指南,但我不明白如何解决此错误:

无效配置 - yii \ base \ InvalidConfigException “query”属性必须是实现QueryInterface的类的实例,例如yii \ db \ Query或其子类。

这是我的代码:

型号/ industrial.php:

<?php

namespace app\models;

use yii\db\ActiveRecord;

class Industrial extends ActiveRecord
{
}

控制器/ IndustrialController.php:

<?php

namespace app\controllers;


use yii\web\Controller;
use yii\data\Pagination;
use app\models\industrial;
use yii\data\ActiveDataProvider;

class IndustrialController extends Controller
{


public function actionIndex()
{
$dataProvider=new ActiveDataProvider('Industrial', array(

'pagination'=>array(
'pageSize'=>20,
),
));
$query = industrial::find();

$pagination = new Pagination([
'defaultPageSize' => 20,
'totalCount' => $query->count(),
]);

$industrials = $query->orderBy('Company_Name')
->offset($pagination->offset)
->limit($pagination->limit)
->all();




return $this->render('index', [
'industrials' => $industrials,
'pagination' => $pagination,
'dataProvider'=>$dataProvider,
]);



}
}

视图/工业/ index.php的:

<?php
use yii\helpers\Html;
use yii\widgets\LinkPager;
?>
<h1>Industrial Companies</h1>
<ul>
<?php

use kartik\export\ExportMenu;

use kartik\grid\GridView;

$gridColumns = [
['class' => 'yii\grid\SerialColumn'],
'id',
'name',
[
'attribute'=>'Name',
'label'=>'Name',
'vAlign'=>'middle',
'width'=>'190px',
'value'=>function ($model, $key, $index, $widget) { 
return Html::a($model->Name, '#', []);
},
'format'=>'raw'
],
'Name',
'Location',
'Telephone',

];
echo ExportMenu::widget([
'dataProvider' => $dataProvider,
'columns' => $gridColumns,
'fontAwesome' => true,
'dropdownOptions' => [
'label' => 'Export All',
'class' => 'btn btn-default'
]
]) . "<hr>\n".
GridView::widget([
'dataProvider' => $dataProvider,
'columns' => $gridColumns,
'export' => [
'fontAwesome' => true,
]
]);



$array = (array) $industrials;



function build_table($array){

// start table

$html = '<table class="altrowstable" id="alternatecolor">';

// header row

$html .= '<tr>';

foreach($array[0] as $key=>$value){

$html .= '<th>' . $key . '</th>';

}

$html .= '</tr>';

// data rows

foreach( $array as $key=>$value){

$html .= '<tr>';

foreach($value as $key2=>$value2){

$html .= '<td>' . $value2 . '</td>';

}

$html .= '</tr>';

}

// finish table and return it

$html .= '</table>';

return $html;

}



echo build_table($array);

?>


<?= LinkPager::widget(['pagination' => $pagination]) ?>

请帮帮我。

在activeDataProvider的配置中

我发现没有为关键字&#39;查询分配值如下

 $ dataProvider = new ActiveDataProvider ([ 
      'query' => Post :: find (),
      'pagination' => [
      'pageSize' => 20,
      ],
 ]);

使用以下

进行测试
actionIndex public function ()
{
    $ dataProvider = new ActiveDataProvider ('Industrial', array (
        'query' => Industrial :: find (),
        'pagination' => array (
        'pageSize' => 20,
        ),
    ));

似乎有错误代码 你应该写:

$ query = Industrial :: find (); 

而不是

$ query = industrial :: find ();

工业类以大写字母

开头

在Yii2文件夹的config / web.php中的组件下添加它,它将起作用

'modules' => [
        'gridview' => [
            'class' => '\kartik\grid\Module',
            ],
         ],
