使用自定义itemView yii2将小部件放置在自定义小部件内

Question

I want to create a custom widget named 'IssueList' which will extend 'ListView'.

<?php
namespace frontend\components;

use yii\base\Widget;
use yii\widgets\ListView;

class IssueList extends Widget{
public $dataProvider;


public function init(){
    parent::init();
}
public function run(){
    return ListView::widget([
        'dataProvider' => $this->dataProvider,
        'itemOptions' => [
            'class' => 'item issue-item'
        ],
        'options' => [
            'class' => 'issue_list'
        ],
        'itemView' => '_issueListView',
        'layout' => '{items}{pager}',
    ]);

}

}?>

However the ListView has a custom itemView. When rendering the widget I get this error

The view file does not exist:

/var/www/clients/client1/web1/frontend/views/comments/_issueListView.php

Its obviously looking in the wrong directory, how do I change this?

Answer 1

itemView is passed to yii\\base\\View render() which is responsible for rendering view. So you can change view path how you want, using aliases if needed:

Renders a view.

The view to be rendered can be specified in one of the following formats:

• path alias (eg "@app/views/site/index");
• absolute path within application (eg "//site/index"): the view name starts with double slashes. The actual view file will be looked for under the view path of the application.
• absolute path within current module (eg "/site/index"): the view name starts with a single slash. The actual view file will be looked for under the view path of the current module.
• relative view (eg "index"): the view name does not start with @ or /. The corresponding view file will be looked for under the view path of the view $context. If $context is not given, it will be looked for under the directory containing the view currently being rendered (ie, this happens when rendering a view within another view).

If you want it to be more dynamic, you can pass closure to itemView with the following signature:

function ($model, $key, $index, $widget) {
    ...
}

See docs for itemView here .

Besides the API Documentation, rendering views and specifying paths is described in official docs in Views (Rendering Views) section.
