php - Octobercms子关系的关系

Question

我正在使用 octobercms 插件，其中有以下模型:

• 房屋
• 付费
• 所有者

在 Houses 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'
      ]
    ];

此关系有一个中间表“author_plugin_houses_owners”:

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

在支付模型中我有以下关系:

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

这个模型对应的表格如下:

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

在表中我有一列“houses_id”，问题是，我如何访问自“Pays”模型以来在“Houses”模型中声明的“所有者”关系？我需要访问它，因为我需要在插件后端的 ListView 上打印“owner_name”。

所有者表:

+----+------------+--------+
| 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 

自从您建立了关系hasMany以来，一所房子可以有多个所有者 [hasManyThrough]

因此这将返回一个所有者列表。

如在 ListView 中需要使用它，您可以定义partial类型列

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中，您可以编写实际逻辑[这必须在PHP中而不是在twig中]

<?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.
