保存关联数据cakephp %3时出错

Question

我无法使用cakephp 3关联保存数据

AddressHeadersTable

$this->hasMany('Addresses', [
            'foreignKey' => 'address_header_id'
        ]);

AddressesTable

$this->belongsTo('AddressHeaders', [
            'foreignKey' => 'address_header_id',
        ]);

控制器代码

$data = [
            'user_id' => 1,
            'company_id' => 4,
            'address' => [
                'user_id' => 1,
                'company_id' => 4,
                'name' => 'Aneh'
            ]
        ];

        $entity = $this->AddressHeaders->newEntity();
        $entity = $this->AddressHeaders->patchEntity($entity, $data, [
            'associated' =>['Addresses']
        ]);
        if($this->AddressHeaders->save($entity)){
            echo "save";
        }else{
            pr($entity->errors());
        }

我们需要在一个地址头id下保存多个地址。当我运行上面代码时，它在address_header中创建了entry，但没有在addresses表中创建任何条目。

你的数据结构应该是这样的：

$data = [
    'user_id' => 1,
    'company_id' => 4,
    'addresses' => [
        [
            'user_id' => 1,
            'company_id' => 4,
            'name' => 'Aneh'
        ]
    ]
];

在保存hasMany关联时，ORM需要使用关联名称

的复数下划线版本命名的实体数组
