saveAll()使用CakePHP 2.3.1失败

我有以下型号：

>艺术家有很多艺术家预览
> ArtistPreview属于艺术家

使用save()函数保存Artist模型没有问题,但是当我尝试使用saveAll方法时,Cake似乎验证失败 – 这很疯狂,因为我甚至完全从模型中删除了所有验证规则.

这是我的观点,没什么了不起的：

<?php
    echo $this->Form->create('Artist',array('inputDefaults' => array('class' => 'input-block-level')));
    echo $this->Form->input('Artist.name',array('label' => __('Name')));
    echo $this->Form->input('Artist.artist_section_id',array('label' => __('Section'),'empty' => true));
?>
<label>Tags</label>
<div class="checkboxes">
    <?php echo $this->Form->input('Tag',array('label' => false,'multiple' => 'checkbox','class' => false));; ?>
</div>
<?php
    echo $this->Form->input('Artist.website',array('label' => __('Website')));
    echo $this->Form->input('ArtistPreview.0.url',array('label' => __('Artist Preview')));
    echo $this->Form->input('Artist.description',array('label' => __('Description')));
?>
<?php

    echo $this->Form->submit(__('Add'),array('class' => 'btn btn-primary btn-large','div' => false)) . ' ';
    echo $this->Form->button(__('Cancel'),array('type' => 'button','class' => 'btn btn-large','div' => false,'onclick' => 'closeDialog()'));
    echo $this->Form->end();
?>

这是我的添加控制器方法：

public function add() {
    $this->layout = 'form';

    if (!$this->request->is('ajax')) {
        throw new ForbiddenException();
    }

    if ($this->request->is('post')) {
        $this->setData($this->request->data['Artist'],array(
            'user_id' => AuthComponent::user('id'),'date' => $this->Date->gmt()
        ));
        if ($this->Artist->saveAll($this->request->data)) {
            $this->redirectAjax('/artists/view/' . $this->Artist->id);
        }
    }

    $this->set(array(
        'title_for_layout' => 'Add Artist','artistSections' => $this->Artist->ArtistSection->find('list',array('order' => 'name')),'tags' => $this->Artist->Tag->find('list',array('order' => 'name'))
    ));
}

如上所述,saveAll方法每次都失败.我已经检查了输出是什么,而Cake正在输出一堆带有错误消息类的空白< div>,但是没有消息.表单上的每个字段都会获得其中一个div.

现在,当我更改我的代码以使用save函数而不是saveAll时,除了ArtistPreview数据之外,所有内容都会被正确保存,这是预期的.甚至我的HABTM标签也正确保存,并且没有任何验证失败.

我从1.3天开始就一直在使用Cake,所以我对它非常熟悉,甚至完成了我之前项目中的要求.我倾向于这是一个错误,除非我在这里遗漏了一些东西.有任何想法吗？

我还尝试了saveAssociated方法,并在尝试保存时将深度键设置为true.这将让我保存艺术家,但不会保存相关数据(ArtistPreview).

根据要求,这是两个表：

-- -----------------------------------------------------
-- Table `artists`
-- -----------------------------------------------------
DROP TABLE IF EXISTS `artists` ;

CREATE  TABLE IF NOT EXISTS `artists` (
  `id` INT UNSIGNED NOT NULL AUTO_INCREMENT,`user_id` INT UNSIGNED NULL,`artist_section_id` INT UNSIGNED NULL,`artist_status_id` INT UNSIGNED NULL,`name` VARCHAR(200) NULL,`website` VARCHAR(500) NULL,`description` TEXT NULL,`date` DATETIME NULL,`comment_count` INT UNSIGNED NOT NULL DEFAULT 0,PRIMARY KEY (`id`),INDEX `FK_artists_users_idx` (`user_id` ASC),INDEX `FK_artists__artist_sections_idx` (`artist_section_id` ASC),INDEX `FK_artists__artist_statuses_idx` (`artist_status_id` ASC),CONSTRAINT `FK_artists__users`
    FOREIGN KEY (`user_id` )
    REFERENCES `users` (`id` )
    ON DELETE SET NULL
    ON UPDATE CASCADE,CONSTRAINT `FK_artists__artist_sections`
    FOREIGN KEY (`artist_section_id` )
    REFERENCES `artist_sections` (`id` )
    ON DELETE SET NULL
    ON UPDATE CASCADE,CONSTRAINT `FK_artists__artist_statuses`
    FOREIGN KEY (`artist_status_id` )
    REFERENCES `artist_statuses` (`id` )
    ON DELETE SET NULL
    ON UPDATE CASCADE)
ENGINE = InnoDB;


-- -----------------------------------------------------
-- Table `artist_previews`
-- -----------------------------------------------------
DROP TABLE IF EXISTS `artist_previews` ;

CREATE  TABLE IF NOT EXISTS `artist_previews` (
  `id` INT UNSIGNED NOT NULL AUTO_INCREMENT,`artist_id` INT UNSIGNED NULL,`url` VARCHAR(500) NULL,INDEX `FK_artist_previews__artists_idx` (`artist_id` ASC),CONSTRAINT `FK_artist_previews__artists`
    FOREIGN KEY (`artist_id` )
    REFERENCES `artists` (`id` )
    ON DELETE CASCADE
    ON UPDATE CASCADE)
ENGINE = InnoDB;

这是我的setData函数,它只合并了两个数组.我没有使用隐藏字段,而是在控制器中设置了未被用户输入填充的字段：

public function setData(&$original,$new) {
    $original = array_merge($original,$new);
}
