Question

我正在使用cakephp 1.3。保存我的HABTM关系时，我遇到了一个非常奇怪的问题。

阅读here，cakephp不会自动保存模型超过2级，我与hasMany和belongsTo建立了HABTM关系。

我有Application-＆gt; Child-＆gt; Membership-＆gt; Club关系。我将模型名称更改为cakephp cookbook中的示例，因为我的应用程序中的真实模型名称不是英文版。

class Child extends AppModel {
var $hasMany = array(
'Membership' => array(
   'foreignKey' => 'child_id'
   ),
}


class Membership extends AppModel {
var $belongsTo = array(
    'Child' => array(
        'foreignKey' => 'child_id'
        ),
    'Club' => array(
        'foreignKey' => 'club_id')
    );
}


class Club extends AppModel {
var $hasMany = array(
    'Membership' => array(
    'foreignKey' => 'club_id'
)
    );
}

以下是Child控制器中正确保存我的孩子的方法 - ＆gt;会员资格＆gt;俱乐部关系

function saveRelated() {
$childId= $this->Child->getLastInsertId(); // get the last inserted child
if(isset($this->data['Club'])) {
    foreach ($this->data['Club'] as $key => $value) {
        if ($this->checkIfEmpty($value)) { // if there was no club submitted in form, then unset array
            unset($this->data['Club'][$key]);
            unset($this->data['Membership'][$key]);
        }
        else {
            $this->data['Membership'][$key]['child_id'] = $childId; // get the child_id from membership join table
            $this->Child->Membership->Club->saveAll($this->data['Club'][$key]); // save the club

                        // from saved club, get club_id
                        $this->data['Membership'][$key]['club_id'] = $this->Child->Membership->Club->getLastInsertId();
                    }
                }
                $this->Child->Membership->saveAll($this->data['Membership']); // save Membership join-table with right ID-s
            }
}

这是我的debug($this->data)

[Application] => Array
        (
            [id] => 361
            [user_id] => 2
            [created] => 2011-09-12 10:45:19
            [modified] => 2011-09-12 10:45:19
            [child_id] => 319
        )
[Child] => Array
    (
        [child_id] => 319
        [kkrid] => KAT-5684746
        [name] => a33
        [x] => 6400000
        [y] => 640000
        [coords] => X: 6400000, Y: 640000
        [Membership] => Array
            (
                [0] => Array
                    (
                        [child_id] => 319
                        [modified] => 2011-09-12 10:45:21.14
                        [membership_id] => 75
                        [club_id] => 478
                    )
                [1] => Array
                    (
                        [child_id] => 319
                        [modified] => 2011-09-12 10:45:21.14
                        [membership_id] => 76
                        [club_id] => 479
                    )
            )

所以我在这里看不到Club阵列？它在哪里？当我想在应用程序中再次编辑表单时，没有俱乐部数据。

俱乐部数据必须在$this->data['Child']['Membership']['Club']，但正如您所见，我的数据阵列中没有。

所有内容都正确保存在数据库中，而我的其他只有hasMany关系的表格保存正确且数据位于$this->data但是为什么来自Club模型的数据来自$this->data？如果必须如此，我的代码中没有任何错误，如何将俱乐部数据手动保存到$this->data？

HABTM模型保存到数据库但不出现在数据数组中
