class ItemController extends Controller
{
    public function actions()
    {
        return [
            'index' => [
                'class' => \yii2tech\admin\actions\Index::class,
                'newSearchModel' => function () {
                    return new ItemSearch();
                },
            ],
            'view' => [
                'class' => \yii2tech\admin\actions\View::class,
            ],
            'create' => [
                'class' => \yii2tech\admin\actions\Create::class,
            ],
            'update' => [
                'class' => \yii2tech\admin\actions\Update::class,
            ],
            'delete' => [
                'class' => \yii2tech\admin\actions\Delete::class,
            ],
        ];
    }

    public function findModel($id)
    {
        if (($model = Item::findOne($id)) !== null) {
            return $model;
        }
        throw new NotFoundHttpException('The requested page does not exist.');
    }

    public function newModel()
    {
        return new Item();
    }
}

Controllers

This extension provides several predefined controllers, which can be used as a base controller classes while creating particular controllers:

• [[\yii2tech\admin\CrudController]] - implements a common set of actions for supporting CRUD for ActiveRecord.

Please refer to the particular controller class for more details.

Widgets

This extension provides several widgets, which simplifies view composition for the typical use cases:

• [[\yii2tech\admin\widgets\Alert]] - renders a message from session flash.
• [[\yii2tech\admin\widgets\ActionAlert]] - renders an action proposition based on particular condition, usually a session flag.
• [[\yii2tech\admin\widgets\ButtonContextMenu]] - simplifies rendering of the context links such as 'update', 'view', 'delete' etc.
• [[\yii2tech\admin\widgets\Nav]] - enhanced version of [[\yii\bootstrap\Nav]], which simplifies icon rendering.

Also several enhancements for the [[\yii\grid\GridView]] are available:

• [[\yii2tech\admin\grid\ActionColumn]] - simplifies composition of the action buttons
• [[\yii2tech\admin\grid\DeleteStatusColumn]] - serves for the 'soft-deleted' status displaying
• [[\yii2tech\admin\grid\PositionColumn]] - provides simple interface for the model custom sort position switching
• [[\yii2tech\admin\grid\VariationColumn]] - allows displaying of the variation column values

Using Gii

This extension provides a code generators, which can be integrated with yii 'gii' module. In order to enable them, you should adjust your application configuration in following way:

return [
    //....
    'modules' => [
        // ...
        'gii' => [
            'class' => yii\gii\Module::class,
            'generators' => [
                'adminMainFrame' => [
                    'class' => yii2tech\admin\gii\mainframe\Generator::class
                ],
                'adminCrud' => [
                    'class' => yii2tech\admin\gii\crud\Generator::class
                ]
            ],
        ],
    ]
];

"MainFrame" generator creates a basic admin panel code, which includes layout files, main controller file and basic view files. The created structure is necessary for the correct rendering of the code created by "Admin CRUD" generator.

"Admin CRUD" generator is similar to regular "CRUD" generator, but it generates code, which uses tools from this extension, so the result code is much more clean.
