Question

我在保存和更新hasMany关联时遇到问题。似乎Cake无法以某种方式正确修补实体。

ProductGroups表：

false

ProductIdentities表：

$this->hasMany('ProductIdentities', [
     'foreignKey' => 'product_group_id',
     'saveStrategy' => 'replace'
]);

ProductGroupsController：

$this->belongsTo('ProductGroups', [
    'foreignKey' => 'product_group_id'
]);

$这 - ＆GT;请求 - ＆GT;数据：

// patch entity
$productGroup = $this->ProductGroups->patchEntity($productGroup, $this->request->data, [
    'associated' => [
        'StaffMembers' => ['onlyIds' => true],
        'ProductIdentities' => ['onlyIds' => true]
    ]
]);

edit.ctp

[
    'group_name' => 'Creative and Performing Arts',
    'active' => '1',
    'product_type_id' => '2',
    'staff_members' => [
        '_ids' => [
            (int) 0 => '103',
            (int) 1 => '11',
            (int) 2 => '3'
        ]
    ],
    'product_identities' => [
        '_ids' => [
            (int) 0 => '1760',
            (int) 1 => '1762',
            (int) 2 => '1763',
            (int) 3 => '1764'
        ]
    ]
]

如果productGroup未与任何productIdentities相关联，则可以保存。但是，如果要选择更多productIdentities或取消选择某些现有属性，则不会保存数据。相反，Cake将在product_identites表中创建新记录。

在进行调试后，我发现Cake没有正确修补实体。见下文：

<?php
    echo $this->Form->input('group_name', 
        ['class' => 'form-control']);
    echo $this->Form->input('active', 
        ['class' => 'form-control']);
    echo $this->Form->input('product_type_id', 
        ['class' => 'form-control']);
    echo $this->Form->input('staff_members._ids', 
        ['options' => $staffMembers, 
         'class' => 'form-control height-200']);
    echo $this->Form->input('product_identities._ids', 
                ['options' => $productIdentities, 
                 'class' => 'form-control height-500']);
?>

onlyIds选项应该阻止Cake创建新记录，但显然它不起作用。

我已将数据格式化为Cake文档中建议的格式，所以我很困惑。

'product_identities' => [
        (int) 0 => object(App\Model\Entity\ProductIdentity) {

            (int) 0 => '1760',
            (int) 1 => '1762',
            (int) 2 => '1763',
            (int) 3 => '1764',
            '[new]' => true,
            '[accessible]' => [
                '*' => true
            ],
            '[dirty]' => [
                (int) 0 => true,
                (int) 1 => true,
                (int) 2 => true,
                (int) 3 => true
            ],
            '[original]' => [],
            '[virtual]' => [],
            '[errors]' => [],
            '[invalid]' => [],
            '[repository]' => 'ProductIdentities'

        }
    ],
