【问题描述】：

对不起，我不得不再问一次，但我正在努力将一个输入保存到两个表中。

我的第一张桌子：

deceases
 - id
 - other records
 - funeral_id
 - cemetery_id

我的第二张桌子：

funerals
 - id
 - other records
 - cemetery_id

我的第三张桌子：

cemeteries
 - id
 - other records

协会：

One decease belongs to a funeral. A funeral has many deceases.
One decease belongs to a cemetery. A cemetery has many deceases.
One funeral belongs to a cemetery. A cemetery has many funerals.

在 DeceasesController 的添加操作中，我想将 cemetery_id 保存到 deceases 和 funerals 中，只有一个输入。

死亡和葬礼的其他输入保存得很好，但我不明白Cakephp的文档如何保存cemetery_id。

DeceasesController：

public function add() 

        $decease = $this->Deceases->newEntity();
        if ($this->request->is('post')) 
            $decease = $this->Deceases->patchEntity($decease, $this->request->data, [
                'associated' => [
                    'Funerals', 
                    'Cemeteries' 
                ]
            ]);
            if ($this->Deceases->save($decease)) 
                $this->Flash->success(__('Saving successfully.'));
                return $this->redirect(['action' => 'index']);
             else 
                $this->Flash->error(__('Saving wasn´t successful. Try again.'));
            
        

        $cemeteries = $this->Deceases->Cemeteries->find('list', ['limit' => 300]);
        $funerals = $this->Deceases->Funerals->find('list', ['limit' => 200]);
        $this->set(compact('decease', 'cemeteries', 'funerals'));
        $this->set('_serialize', ['decease']);
    

add.ctp 的片段：

echo $this->Form->input('funeral.cemetery_id', ['options' => $cemeteries, 'label' => 'cemetery']);

希望您能够理解我的问题。英语不是我的第一语言。

提前致谢。

【参考方案1】：

希望我能理解你的问题：

在patchEntity 之后和保存之前在您的控制器中，您可以这样做

$decease->cemetery_id = $decease->funeral->cemetery_id;

因此，死亡和葬礼都将设置相同的值

完美。非常感谢你。
