这是一个扩展，它允许轻松创建不同ActiveRecord模型之间的联系。

安装

通过 composer 安装此扩展是首选方式。

运行以下命令之一

php composer.phar require --prefer-dist vtvz/yii2-relations

或

"vtvz/yii2-relations": "*"

将以下内容添加到您的composer.json文件的require部分。

用法

vtvz\relations\Relations 类是行为。

行为支持所有类型的关联，并允许方便地对其进行配置。

示例

<?php
namespace common\models;

use vtvz\relations\Relations;

class Order extends Model
{
    public function behaviors()
    {
        return [
            'relations' => [
                'class' => Relations::className(),
                'relations' => [
                    /* many to many relation type */
                    'items' => [
                        'model' => Item::className(),
                        'link' => ['id' => 'itemId'],
                        'viaTable' => 'order_has_item',
                        'viaLink' => ['orderId' => 'id'],
                        'inverseOf' => 'orders',
                    ],
                    /* one (customer) to many (orders) relation type */
                    'customer' => [
                        'model' => Customer::className(),
                        'link' => ['id' => 'customerId'],
                        'type' => 'one',
                    ],
                    /* one to one relation type with delete */
                    'orderInfo' => [
                        'model' => OrderInfo::className(),
                        'link' => ['id' => 'id'],
                        'type' => 'one',
                        'delete' => true,
                    ],
                    /* many (somethings) to one (order) relation type.
                    All somethings deletes with its order */
                    'somethings' => [
                        'model' => Something::className(),
                        'link' => ['orderId' => 'id'],
                        'type' => 'many',
                    ]
                ],
            ],
        ];
    }
}
?>
