How to move actioncolumn?

Question

Yii

There is an actioncolumn in yii2, I reassign these buttons, but given that there are plenty of controllers, and not repeating the code from the reassignment, how to transfer them to a separate component? The code itself

['class' => 'yii\grid\ActionColumn',
'template' => '{view} {update} {delete}',
'buttons' => [
    'view' => function ($url, $model, $key) {
        return Html::a('<span class="fa fa-eye"></span>', $url, [
            'title' => Yii::t('backend', 'View'),
            'class' => 'btn btn-success btn-sm',
        ]);
    },
    'update' => function ($url, $model, $key) {
        return Html::a('<span class="fa fa-pencil-square-o"></span>', $url, [
            'title' => Yii::t('backend', 'Update'),
            'class' => 'btn btn-primary btn-sm',
        ]);
    },
    'delete' => function ($url, $model, $key) {
        return Html::a('<span class="fa fa-trash"></span>', $url, [
            'title' => Yii::t('backend', 'Delete'),
            'data-confirm' => 'Are you sure you want to delete?',
            'class' => 'btn btn-danger btn-sm',
        ]);
    },
],
],

I try through

<?php
namespace common\components;

use \yii\grid\Actioncolumn;
use \yii\helpers\Html;

class ActionButton extends ActionColumn {

function init() {
  parent::init();
  $this->initDefaultButtons();
}

protected function initDefaultButtons()
{
 $this->buttons['view'] = function ($url, $model, $key) {
        return Html::a('<span class="fa fa-eye"></span>', $url, [
            'title' => Yii::t('backend', 'View'),
            'class' => 'btn btn-success btn-sm',
        ]);
    };
}

}

but it turns out some bullshit. Error upon error.
How in general is it smart to transfer duplicate code to other files?

Answer 1

You have a regular array in buttons, the same as in params.php (in configs).
No one forbids doing the same in this situation.
In other cases, code duplication may be handled differently.
