CakePHP：保存相关数据 [英] CakePHP: saving associated data

问题描述

我试图保存IssueHistoryDe​​scription，它属于IssueHistory。
所以IssueHistory有很多IssueHistoryDe​​scription。

I'm trying to save IssueHistoryDescription, which belongsTo IssueHistory. So IssueHistory hasMany IssueHistoryDescription. This has all been set in the model.

然而，当我在IssueHistory中保存时，使用 $ IssueHistory-> save（$ data） ;

Yet, when I save this in IssueHistory, using $IssueHistory->save($data);

（有或没有 $ IssueHistory-> create（）; before ...）

(With or without a $IssueHistory->create(); before...)

Array
(
    [IssueHistory] => Array
        (
            [id] => 22
        )

    [IssueHistoryDescription] => Array
        (
            [old_description] => OLD
            [description] => NEW
        )

)

不起作用，不保存任何内容。

It doesn't work, nothing is saved.

当我尝试使用 saveAssociated（）时出现错误：

When I try to use saveAssociated() I get an error:

致命错误：不能在第2248行的/var/www/xdev/kipdomanager/cakephp/lib/Cake/Model/Model.php中将字符串偏移量用作数组

Fatal error: Cannot use string offset as an array in /var/www/xdev/kipdomanager/cakephp/lib/Cake/Model/Model.php on line 2248

推荐答案

您可以尝试：

$data = array(
    'IssueHistory' => array('id' => 2),
    'IssueHistoryDescription' => array(
        array('old_description' => 'OLD', 'description' => 'new')
    )
);

$IssueHistory->create();
$IssueHistory->saveAll( $data );
