GridView игнорирует заголовки полей, если таблица пуста.

[m00nk]

Если в выводимой таблице есть содержимое, то заголовки столбцов берутся из массива, который возвращает Model::attributeLabels(), но если таблица выводится пустой (одна строка "Ничего не найдено."), то в заголовки столбцов попадают просто имена полей из БД, т.е. значение из Model::attributeLabels() просто игнорируется.

Есть идеи, как это поправить?

Could't reproduce. Is i18n component properly configured and language files placed in right directories?

[SilverFire]

Also failed to reproduce. @m00nk, could you show code from the view?

I have the same issue. It's pretty easy to reproduce. I'm using ArrayDataProvider with array of models. When array is empty, attributeLabels method is not used, because it's not even possible for GridView to know which model to use.

@flowip for ArrayDataProvider that's understandable. Original issue seems to be about ActiveDataProvider.

Maybe, @m00nk didn't mention that. I myself have to create empty model object, get labels from it and pass labels to view.

@m00nk ?

Yes, I use ArrayDataProvider and GridView.

echo \yii\grid\GridView::widget([
    'layout' => '{items}{pager}',
    'dataProvider' => new \yii\data\ArrayDataProvider([
        'allModels' => SitemapNode::find()-> /* ... */ ->all(),
        'pagination' => ['pageSize' => 20]
    ]),

    'columns' => [

        [
            'class' => \yii\grid\CheckboxColumn::className(),
            'checkboxOptions' => function ($model, $key, $index, $column)
            { return ['value' => $model->id, 'class' => 'node_checkbox'];   },
        ],

        'id',

        [
            'attribute' => 'title',
            'format' => 'raw',
            'contentOptions' => ['class' => 'column_title'],
            'value' => function ($model)
            {
                /** @var $model SitemapNode */
                return
                    $model->menu_title
                    .Html::a(
                        '<span class="pull-right glyphicon glyphicon-pencil"></span>',
                        ['edit', 'id' => $model->id],
                        ['title' => Yii::t('moduleBlog', 'Редактировать страницу')]
                    );
            }
        ],

        [
            'attribute' => 'alias',
            'format' => 'raw',
            'value' => function ($model)
            {
                /** @var $model SitemapNode */
                return
                    Html::a($model->alias, $model->getPageUrl(), ['title' => Yii::t('moduleBlog', 'Открыть страницу в новом окне'), 'target' => '_blank']);
            }
        ],
/* ... */
    ],
]);

I have written a fairly elegant solution for that problem if you are using a Model cast to an array and a filterModel.

<?php

namespace app\base;

use yii\base\Model;
use yii\data\ArrayDataProvider;

class DataColumn extends \yii\grid\DataColumn
{
    /**
     * @inheritdoc
     */
    protected function renderHeaderCellContent()
    {
        $filterModel = $this->grid->filterModel;
        if ($this->label === null && $this->grid->dataProvider instanceof ArrayDataProvider && $filterModel instanceof Model) {
            $this->label = $filterModel->getAttributeLabel($this->attribute);
        }
        return parent::renderHeaderCellContent();
    }
}

Then it's enough to add
'dataColumnClass' => 'app\base\DataColumn',
to your GridView configuration.

@artur-ciesielski looks good :)
