Octobercms 子关系之关系

Question

我在 octobercms 插件中工作，其中有以下模型：

房子
支付
所有者

在房屋模型中，我有以下关系：

public $hasManyThrough = [
      'owner' => [
        'Author\Plugin\Models\Owner',
        'table' => 'author_plugin_houses_owners',
        'key' => 'houses_id',
        'otherKey' => 'owners_id'
      ]
    ];

这个关系有一个中间table 'author_plugin_houses_owners':

+------------+-------------+--------+
| hoses_id   |  owners_id  | active |
+------------+-------------+--------+

在付费模型中，我有以下关系：

public $belongsTo = [
        'houses' => ['Author\Plugin\Models\Houses']
];

这个模型对应一个table是这样的：

+----+----------+---------+-------+------+
| id | hoses_id | amounth | payed | debt |
+----+----------+---------+-------+------+

在 table 中，我有一列 "houses_id"，问题是，我如何访问 "Houses" 模型中声明的 "owner" 关系，因为 "Pays" 模型？我需要访问它，因为我需要在插件后端的列表视图中打印 "owner_name"。

所有者table:

+----+------------+--------+
| id | owner_name | active |
+----+------------+--------+

非常感谢！

Answer 1

我假设Pay只属于一所房子。

public $belongsTo = [        
    'house' => ['Author\Plugin\Models\Houses'] 
  // ^ you can use house instead houses for relation name
];

现在我们可以通过关系链访问所有者

$payModel->house->owner

因为you made relation hasMany一个房子可以有多个owners[hasManyThrough]

所以这将 return 你的列表 owners。

因为在list view你需要使用它，你可以定义partial类型的列

columns:
    id:
        label: id
        type: number
        searchable: true
        sortable: true

    .... other fields ...

    owner_name:
        label: Owner
        type: partial
        path: $/hardiksatasiya/demotest/models/sort/_ownername_column.htm

Make sure to replace the path with your own plugin author name and path.

现在在 partial 里面，你可以写你的实际逻辑 [这必须在 PHP 而不是在 twig ]

<?php
// this is hasmany relation so we expect multiple owners
$owners = $record->house->owner;
$ownerArr = [];
foreach($owners as $ownr) {
    $ownerArr[] = $ownr->owner_name;
}
$output = implode($ownerArr, ', ');
?>

<?php echo $output ?>

If there is only one owner it will show Hardik one name only if there are multiple owners it will show Hardik, Noe comma separated values.

如有疑问请评论。
