更新到 _joinData 中的值有效但缺少正确的索引

Question

经过大量工作，我终于找到了如何更新联接 table，但我发现了一些我绝对无法解决的问题。我手动添加了一组复选框来更新我加入 table 上的一个项目并且几乎完美地工作，只要它们是我的遗留数据库的一部分。当我将新项目添加到具有较低 ID 的连接 table 时，我的连接 table 上的错误项目将被更新。

我的控制器是这样的：

public function edit($id)
{

    $brigada = $this->Brigadas
        ->findById($id)
        ->contain(['Tags', 'Voluntarios'])
        ->firstOrFail();

    if ($this->request->is(['patch', 'post', 'put'])) {
        // https://github.com/cakephp/cakephp/issues/7864
        if (!empty($this->request->data['voluntarios']['_ids'])) {
            $vol = [];
            $ids = [];
            foreach ($this->request->data['voluntarios']['_ids'] as $key=>$locationId) {

                $vol['_ids'][$key] = $locationId;

                $vol[] = [
                    '_joinData' => [
                        'lider' => isset($this->request->data['voluntarios'][$key]['_joinData']['lider']) ? $this->request->data['voluntarios'][$key]['_joinData']['lider'] : false
                    ]
                ];


            }
        }

        if (isset($vol)){                
            $this->request->data['voluntarios'] = $vol;
        }

        $this->Brigadas->patchEntity($brigada, $this->request->data, ['associated' => ['Voluntarios._joinData', 'Participaciones', 'Participaciones._joinData']]);

        if ($this->Brigadas->save($brigada)) {
            $this->Flash->success(__('Your team data has been updated.'));
            return $this->redirect(['action' => 'view', $id]);
        }
        $this->Flash->error(__('Unable to update your team data.'));
    }
}

这就是我迭代表单的方式。注意到我为 id 添加了一个额外的隐藏表单，只是为了尝试更改 id 号。但是最后结果完全一样

    foreach($all_vol as $key=>$voluntario){
        echo $this->Form->control('voluntarios.'.$key.'.id', ['hidden' => true]);
        echo $this->Form->control('voluntarios.'.$key.'._joinData.lider', [
            'label' => $voluntario->full_name,
            'default'=>'0',
        ]);
    }

这是表单发送的请求。

我在底部添加了 id 为 1 和 2 的项目并将它们变成 'lider'，但是当它们传递给 patchEntity 时，两个不同的项目被选为 'lider'。这是手动编辑后的请求。

        (int) 16 => '7864'
    ]
]

最后，我是否手动编辑并不重要，因为我在 patchEntity 调用中得到了它。请注意 'id' 既不是 1 也不是 2:

    '_joinData' => object(App\Model\Entity\Participacione) {
        'id' => (int) 981,
        'brigada_id' => (int) 222,
        'voluntario_id' => (int) 7567,
        'lider' => true,
        '[new]' => false,
        '[accessible]' => [
            'brigada_id' => true,
            'voluntario_id' => true,
            'lider' => true,
            'brigada' => true,
            'voluntario' => true

我该如何解决这个问题？我已经发布了其他没有很多答案的问题，但我会继续相信人性来解决这个问题。预先感谢您阅读我的问题！

Answer 1

令人惊讶的是，我设法通过在 table 中使用排序属性来解决它。像这样：

$this->belongsToMany('Voluntarios', [
        'foreignKey' => 'brigada_id',
        'targetForeignKey' => 'voluntario_id',
        'joinTable' => 'participaciones',
        'saveStrategy' => 'replace',
        'through' => 'Participaciones',
        'sort' => ['Voluntarios.id' => 'ASC'],
    ]);

我觉得一切都很勉强，但我找不到更好的方法。我在删除带星号的值时发现了一些错误，但这是朝着正确方向迈出的一步。

更新到 _joinData 中的值有效但缺少正确的索引

Update to value in _joinData works but misses right index
