重新格式化cakephp找到线程

Question

我的目标是使用树对象来存储发票。我遇到的问题是它总是在每个后​​续子项周围放置一个“Invoice”模型包装器。我试着得到结果并使用Set类来清理冗余的“发票”，“孩子们”，但我无法弄清楚如何让它工作。我在API中使用它，所以基本上我想要做的就是在阵列中上下移动而不必经常发票.children.invoice.children

在我的控制器中我有：

  $results = $this->Invoice->find('threaded', array(
      'order' => array('lft ASC') // or array('id ASC')
      ));

  $this->set(array(
    'results' => $results,
    '_serialize' => 'results'
    ));

我得到的是：

{
    "success": true,
    "data": [
        {
            "id": 1,
            "parent_id": null,
            "lft": 1,
            "rght": 30,
            "name": "Invoices",
            "children": [
                {
                    "Invoice": {
                        "id": 2,
                        "parent_id": 1,
                        "lft": 2,
                        "rght": 15,
                        "text": "invoice 001"
                    },
                    "children": [
                        {
                            "Invoice": {
                                "id": 3,
                                "parent_id": 2,
                                "lft": 3,
                                "rght": 8,
                                "text": "invoice_item"
                            },
                            "children": [
                                {
                                    "Invoice": {
                                        "id": 4,
                                        "parent_id": 3,
                                        "lft": 4,
                                        "rght": 5,
                                        "text": "invoice_sub_item"
                                    },
                                    "children": []
                                },
                                {
                                    "Invoice": {
                                        "id": 5,
                                        "parent_id": 3,
                                        "lft": 6,
                                        "rght": 7,
                                        "text": "subitem#2"
                                    },
                                    "children": []
                                }
                            ]
                        }
                    ]
                }
            ]
        }
    ]
}

理想情况下，我想

invoices.invoice.text = "invoice 001"

和

invoices.invoice.invoice_item[0].text  = "invoice_item"

显然我需要添加/删除数组并重新提交更改。这是可能的还是我只是让自己变得更难？
