提问by WebArtisan
What data must be sended to dataprovider?
哪些数据必须发送给数据提供者？
In my controller:
在我的控制器中：
public function actionIndex() {
$searchModel = new UserSearch();
$dataProvider = $searchModel->search( Yii::$app->request->queryParams );
//other stuff and sending array of params to view
in a view:
在一个观点：
echo ListView::widget( [
'dataProvider' => $dataProvider,
] );
but i got only id`s:
但我只有身：
And if i`m set single view like:
如果我设置了单个视图，例如：
'itemView' => '_single',
how send data to _single.php ?
如何将数据发送到 _single.php ？
I mean - need default template for view list items like in GridView:
我的意思是 - 需要像 GridView 这样的视图列表项的默认模板：
GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'id',
'username',
'email:email',
'password',
'role',
//....
And then i got perfect grid:
然后我得到了完美的网格：

how send data to _single.php ?Here is how, use $viewParams
how send data to _single.php ?这是如何使用 $viewParams
$viewParams public property array $viewParams = []
Additional parameters to be passed to $itemView when it is being rendered. This property is used only when $itemView is a string representing a view name.
$viewParams 公共属性数组 $viewParams = []
渲染时传递给 $itemView 的附加参数。仅当 $itemView 是表示视图名称的字符串时才使用此属性。
echo ListView::widget( [
'dataProvider' => $dataProvider,
'viewParams'=>['name'=>'My Name is Stefano'], //acccessed in view as $name with value 'My Name is Stefano'
] );

in official docs http://www.yiiframework.com/doc-2.0/yii-widgets-listview.html#$itemView-detail
在官方文档http://www.yiiframework.com/doc-2.0/yii-widgets-listview.html#$itemView-detail
$itemView public property
The name of the view for rendering each data item, or a callback (e.g. an anonymous function) for rendering each data item. If it specifies a view name, the following variables will be available in the view:
$model:mixed, the data model
$key:mixed, the key value associated with the data item
$index:integer, the zero-based index of the data item in the items array returned by $dataProvider.
$widget:ListView, this widget instance
$itemView 公共属性
用于呈现每个数据项的视图的名称，或用于呈现每个数据项的回调（例如匿名函数）。如果它指定了视图名称，则视图中将提供以下变量：
$model：混合，数据模型
$key：混合，与数据项关联的键值
$index：整数，$dataProvider 返回的 items 数组中数据项的从零开始的索引。
$widget：ListView，这个widget实例
So your User model data should be available in _single.php as $model->username
所以你的用户模型数据应该在 _single.php 中作为$model->username可用
回答by WebArtisan
So i suppose can use Detail View in _single.php i think:
所以我想可以在 _single.php 中使用 Detail View 我认为：
DetailView::widget([
'model' => $model,
'attributes' => [
'id',
'username',
'email:email',
//....
