Model-show Extension

since v1.6.12

This feature is used to extend the detail field display. This can be implemented using the built-in display method that does not meet the requirements.

First define the extension class:

<?php

namespace App\Admin\Extensions\Show;

use OpenAdmin\Admin\Show\AbstractField;

class UnSerialize extends AbstractField
{
    public function render($arg = '')
    {
        // return any content that can be rendered
        return unserialize($this->value);
    }
}

Then register the extension class in app/Admin/bootstrap.php

use OpenAdmin\Admin\Show;
use App\Admin\Extensions\Show\UnSerialize;

Show::extend('unserialize', UnSerialize::class);

Then use this extension in the controller

$show->column()->unserialize('xxx');

The arguments passed to the unserialize() method are passed to the UnSerialize::render() method in order.

You can see several common properties in the parent class OpenAdmin\Admin\Show\AbstractField.

    /**
     * Field value.
     *
     * @var  mixed
     */
    protected $value;

    /**
     * Current field model.
     *
     * @var  Model
     */
    protected $model;

    /**
     * If this field show with a border.
     *
     * @var  bool
     */
    public $border = true;

    /**
     * If this field show escaped contents.
     *
     * @var  bool
     */
    public $escape = true;

Where $value and $model are the current field values ​​and the current data model, which can be used to get the data you want in the render() method.

$border is used to control whether the current display content requires an outer border, and $escape is used to set the current display content to be HTML-escaped.
