                    'shoots_id' => [
                        '_required' => 'This field is required'
                    ]
                ],
                'repository' => 'ShootMeta'

            }
        ],
        'created_by' => (int) 1
    ],
    'dirty' => [
        'title' => true,
        'content' => true,
        'datetime' => true,
        'shoot_meta' => true,
        'created_by' => true
    ],
    'original' => [],
    'virtual' => [],
    'errors' => [],
    'repository' => 'Shoots'

}

如你所见，字段shoots_id是必需的，我本以为它会自动传递下来（虽然此时它还没有执行任何MySQL）。

我觉得我可能以错误的方式解决了这个问题，但我花了整整 2 天的时间试图把它弄好。有一天，我试图弄清楚为什么在烘焙后它把很多对 ShootMeta 的引用命名为 ShootMetum，我认为它实际上已经破坏了它。

我遇到的最大问题之一是不知道在哪里使用 shoot_meta、ShootMeta、shootmeta、shootmetum、ShootMetum 等。感觉有点雷区！

/更新

以下保存对象的转储。明明是在赋值，只是好像没有在SQL?

执行

'shoot_meta' => [
            (int) 0 => object(App\Model\Entity\ShootMetum) {

                'new' => false,
                'accessible' => [
                    'shoots_id' => true,
                    'meta_key' => true,
                    'meta_value' => true
                ],
                'properties' => [
                    'meta_key' => 'photographer_spaces',
                    'meta_value' => '123',
                    'shoot_id' => '2',
                    'id' => '3'
                ],
                'dirty' => [],
                'original' => [],
                'virtual' => [],
                'errors' => [],
                'repository' => 'ShootMeta'

            },

Answer 1

删除 shoots_id 的验证规则。验证是针对从表单发布的数据，在这种情况下不能从表单发布 foreignKey。您的 buildRules() 方法中已经有规则来确保在保存之前传递值，因此删除验证是 100% 安全的。

Answer 2

找到了。

调试存档时指的是shoot_id

'shoot_meta' => [
            (int) 0 => object(App\Model\Entity\ShootMetum) {
                'new' => false,
                'accessible' => [
                    'shoots_id' => true,
                    'meta_key' => true,
                    'meta_value' => true
                ],
                'properties' => [
                    'meta_key' => 'photographer_spaces',
                    'meta_value' => '123',
                    'shoot_id' => '2',
                    'id' => '3'
                ],
                'dirty' => [],
                'original' => [],
                'virtual' => [],
                'errors' => [],
                'repository' => 'ShootMeta'

            },

出于某种原因，它使用了协会的单数名称。在 Shoots.php 模型中更改。

来自

$this->hasMany('ShootMeta');

至

$this->hasMany('ShootMeta',[
    'foreignKey' => 'shoots_id'
]);

我遇到了同样的问题，目前我的解决方案是将相关数据发送给其他 function/methode 并保存。例如

**

public function add() {
        $kantor = $this->Kantor->newEntity($this->request->data);
        if ($this->request->is('post')) {
            $kantor = $this->Kantor->patchEntity($kantor, $this->request->data);
            $rgndata = $this->request->data['Telpkantor'];
            $this->request->session()->write('rgndata', $rgndata);
            if ($this->Kantor->save($kantor)) {
                $result = $this->Kantor->save($kantor);
                $this->addTelpKantor($rgndata, $result->id);
                $this->Flash->success('The kantor has been saved.');
                return $this->redirect(['action' => 'index']);
            } else {
                $this->Flash->error('The kantor could not be saved. Please, try again.');
            }
        }
        $reffKota = $this->Kantor->ReffKota->find('list', ['limit' => 200]);
        $statusKantor = $this->Kantor->StatusKantor->find('list', ['limit' => 200]);
        $pimpinan = $this->Kantor->Pimpinan->find('list', ['limit' => 200]);
        $jenisTelp = $this->Kantor->Telpkantor->Jenistelp->find('list', ['limit' => 200]);
        $this->set(compact('kantor', 'reffKota', 'statusKantor', 'pimpinan', 'jenisTelp'));
        $this->set('_serialize', ['kantor']);
    }
    public function addTelpKantor($rgndata = null, $kantor_id=null) {
        if (!empty($rgndata[0]['noTelp'])) {
            $this->loadModel('Telpkantor');
            foreach ($rgndata as $rgndata) {
                $rgndata['kantor_id'] =$kantor_id;
                $rgndatasave = $this->Telpkantor->newEntity($rgndata);
                $this->Telpkantor->save($rgndatasave);
            }
        }
    }
