从模型中的关系中获取全名

Question

我有模型博客，我在那里有关系：

public function getRelUser()
    {
        return $this->hasOne(UrUser::className(), ['Id' => 'Rel_User']);
    }

我想在我的博客索引中使用全名在网格视图中查看：

<?= GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'columns' => [
            ['class' => 'yiigridSerialColumn'],
            'Id',
            'Title',
            'Description',
            'Rel_User',
            [
        'attribute' => 'Rel_User',
        'value' => 'relUser.Name'
        ], 
            'CreatedAt',
            // 'IsDeleted',
            ['class' => 'yiigridActionColumn'],
        ],
    ]); ?>

这只返回我列中的名字。我想返回全名。

Answer 1

在 UrUser 模型中添加新方法：

class UrUser extends yiidbActiveRecord
{
    ....
    public function getFullName()
    {
        return $this->name .' '. $this->last_name;
    }
}

并在您的视图中使用它，如下所示：

<?= GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'columns' => [
            ['class' => 'yiigridSerialColumn'],
            'Id',
            'Title',
            'Description',
            'Rel_User',
            [
                'attribute' => 'Rel_User',
                'value' => function ($model) {
                    return $model->relUser->getFullName();
                },
             ], 
            'CreatedAt',
            // 'IsDeleted',
            ['class' => 'yiigridActionColumn'],
        ],
    ]); ?>

Answer 2

试试这个

<?= GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'columns' => [
            ['class' => 'yiigridSerialColumn'],
            'Id',
            'Title',
            'Description',
            'Rel_User',
            [
        'attribute' => 'Rel_User',
        'value' => function($model) { 
              return $model->relUser->name  . " " . $model->relUser->last_name ;
            },
        ], 
            'CreatedAt',
            // 'IsDeleted',
            ['class' => 'yiigridActionColumn'],
        ],
    ]); ?>

CDetailView的更新。这应该有效

[
  'label'=>'Full Name',
  'value'=>'$data->relUser->name . " " . $data->relUser->last_name',
]
