cakephp保存多个数据hasmany relation

Question

我试图一次保存多个数据，但无法保存数据。

我有Post的模型和评论模型。

Post有很多评论。

$this->WhAreaAllocation->saveAll($tempArray, array('deep' => true));

$tempArray如下：

array(
    'post' => array(
        (int) 0 => array(
            'title' => 'title1',
            'content' => 'content1',
            'comment' => array(
                (int) 0 => array(
                    'comment'=>'1st comment for post 1'
                ),
                (int) 1 => array(
                    'comment'=>'2nd comment for post 1'
                )
            )
        ),
        (int) 1 => array(
        'title' => 'title2',
            'content' => 'content2',
            'comment' => array(
                (int) 0 => array(
                    'comment'=>'1st comment for post 2'
                ),
                (int) 1 => array(
                    'comment'=>'2nd comment for post 2'
                )
            )
        )
    )
)

<强> Saving hasMany through data

我不知道您是使用表单保存帖子评论，而且我不确定您使用的是哪个版本的 cakephp ，但我的解决方案是 cakephp2.x < / strong>。如果您想使用表单保存数据，那么创建这样的帖子表格，并保存在字段中有许多提到的相关型号名称。例如，这里你想保存相关的帖子评论见下面的代码

<?php echo $this->Form->create('Post'); ?>
    <?php echo $this->Form->input('Post.title'); ?>
    <?php echo $this->Form->input('Post.content'); ?>
    <?php echo $this->Form->input('Comment.comment'); ?>
    <button type="submit">Save</button>
<?php echo  $this->Form->end(); ?>

使用此表单，您将获得这样的请求数据。

Array
(
    [0] => Array
    (
        [Post] => Array
        (
            [title] => It is a post title
            [content] => you post content
        )

        [Comment] => Array
        (
            [comment] => this is my post comment
        )


    )
)

或者如果你想使用表格保存数据，那么你必须创建这样的数据，并且还要看 CakePhp Save hasmany

Array
    (
        [0] => Array
        (
            [Post] => Array
            (
                [title] => It is a post title
                [content] => you post content
            )

            [0] => Array
            (
                [Comment] => Array
                (
                    [comment] => this is my post comment1
                )
            )

           [1] => Array
            (
                [Comment] => Array
                (
                    [comment] => this is my post comment2
                )
            )



        )
    )
