CakePHP 3.0无法保存hasMany关联数据

Question

使用hasMany关联保存数据时遇到问题

这是我的桌子

1)邮政表:每个项目都有一个唯一的ID.

id | title | ... 
1  | Aloha | ...

2)图像表

id | post_id | image   | ...  
1  | 1       | abc.jpg | ...
2  | 1       | efg.jpg | ...

我的模型(表)

帖子模型

// PostsTable.php
<?php

namespace App\Model\Table;

use Cake\ORM\Query;
use Cake\ORM\Table;
use Cake\Validation\Validator;

class PostsTable extends Table {
     public function initialize(array $config) {
        $this->table('posts');
        $this->displayField('title');
        $this->primaryKey('id');
        $this->addBehavior('Timestamp');
        $this->hasMany('Images', [
           'foreignKey' => 'id'
        ]);
     }
}

...

图像模型

// ImagesTable.php
<?php

namespace App\Model\Table;

use Cake\ORM\Query;
use Cake\ORM\Table;
use Cake\Validation\Validator;

class ImagesTable extends Table {
     public function initialize(array $config) {
        $this->table('images');
        $this->displayField('id');
        $this->primaryKey('id');
        $this->addBehavior('Timestamp');
        $this->belongsTo('Posts');
     }
}

...

我的控制器

// PostsController.php
...
public function add() {
    $post = $this->Posts->newEntity($this->request->data, [
        'associated' => ['Images']
    ]);

    if ($this->request->is('post')) {
        if ($this->Posts->save($post, ['associated' => ['Images']])) {
            $this->Flash->success('The post has been saved.');
            return $this->redirect(['action' => 'index']);
        } else {
            $this->Flash->error('The post could not be saved. Please, try again.');
        }
    }

    $this->set('post', $post);
}

...

我的模板

// add.ctp
<?= $this->Form->create($post); ?>

<?php echo $this->Form->input('title'); ?>

<?php echo $this->Form->input('images.0.image'); ?>
<?php echo $this->Form->input('images.1.image'); ?>
<?php echo $this->Form->input('images.2.image'); ?>

<?= $this->Form->button(__('Submit'), ['class' => 'button-green']) ?> 

<?= $this->Form->end() ?>

输入数组结果Debug

[
   'title' => 'Hello',
   'images' => [
       (int) 0 => [
           'image' => 'testa.jpeg'
       ],
       (int) 1 => [
           'image' => 'testb.jpeg'
       ],
       (int) 2 => [
           'image' => 'testc.jpeg'
       ]
   ]
]

(更新) debug($ post)

object(App\Model\Entity\Story) {

    'new' => true,
    'accessible' => [
        'title' => true,
        'images' => true
    ],
    'properties' => [

        'images' => [
            (int) 0 => object(App\Model\Entity\Image) {

            },
            (int) 1 => object(App\Model\Entity\Image) {

                'new' => true,
                'accessible' => [

                'dirty' => [
                    'image' => true
                ],
                'original' => [],
                'virtual' => [],
                'errors' => [],
                'repository' => 'Images'

            },
            (int) 2 => object(App\Model\Entity\Image) {

                'new' => true,
                'accessible' => [
                    'post_id' => true,
                    'image' => true,
                    'post' => true
                ],
                'properties' => [
                    'image' => 'testc.jpeg'
                ],
                'dirty' => [
                    'image' => true
                ],
                'original' => [],
                'virtual' => [],
                'errors' => [],
                'repository' => 'Images'

            }
        ]
    ],
    'dirty' => [
        'title' => true,
        'images' => true
    ],
    'original' => [],
    'virtual' => [],
    'errors' => [],
    'repository' => 'Stories'

}

我无法弄清楚我做错了什么

谢谢

Answer 1

尝试这个 ：

<?php echo $this->Form->input('0.Images.image'); ?>
<?php echo $this->Form->input('1.images.image'); ?>
<?php echo $this->Form->input('2.images.image'); ?>

之前有 int ，根据http://book.cakephp.org/3.0/en/views/helpers/form.html#field-naming-conventions
