我正在构建一个 CakePHP 2.3 应用程序,但我一辈子都无法弄清楚为什么 saveAll 总是失败。
我有以下型号:
Artist
有很多ArtistPreview
ArtistPreview
属于Artist
我用
Artist
函数保存我的 save()
模型没有问题,但是一旦我尝试使用 saveAll
方法,Cake 似乎验证失败 - 这很疯狂,因为我什至完全删除了所有验证我的模型规则。
这是我的观点,没什么疯狂的:
<?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
add
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'))
));
}
正如我上面提到的,saveAll 方法每次都会失败。我检查了正在输出的内容,并且 Cake 正在输出一堆带有
<div>
类的空白 error-message
,但没有消息。表单上的每个字段都有这些 div 之一。
现在,当我更改代码以使用
save
函数而不是 saveAll
时,除了 ArtistPreview
数据之外,所有内容都会正确保存,这是预期的。甚至我的 HABTM 标签也已正确保存,没有任何内容无法通过验证。
我从 1.3 天起就开始使用 Cake,所以我对它非常熟悉,甚至完全按照我在之前项目中的要求做了。我倾向于这是一个错误,除非我在这里遗漏了一些东西。有什么想法吗?
编辑
我还尝试了
saveAssociated
方法,以及在尝试保存时将deep
键设置为true
。这会让我保存艺术家,但不会保存相关数据(ArtistPreview)。

根据要求,这是两个表格:
-- -----------------------------------------------------
-- 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 ,
`date` DATETIME NULL ,
PRIMARY KEY (`id`) ,
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,它只是合并两个数组。我没有使用隐藏字段,而是在控制器中设置了不由用户输入填充的字段:
public function setData(&$original, $new) {
$original = array_merge($original, $new);
}
所以我终于弄清楚了,哇,这是一个菜鸟错误。我想我昨天编码时一定是半睡半醒。问题出在我的模型中:
class Artist extends AppModel {
public $belongsTo = array(
'User',
'ArtistSection',
'ArtistStatus'
);
public $hasMany = array(
'ArtistPicture',
'Artist' // <--- problem was here, had 'Artist' instead of 'ArtistPreview'
);
public $hasAndBelongsToMany = array(
'Tag'
);
public function __construct($id = false, $table = null, $ds = null) {
parent::__construct($id, $table, $ds);
$this->validate = array(
'name' => array(
'rule' => 'notEmpty',
'message' => __('Artist name cannot be blank.')
),
'website' => array(
'rule' => 'url',
'message' => __('Must be a valid URL.'),
'allowEmpty' => true
),
'artist_section_id' => array(
'rule' => 'notEmpty',
'message' => __('Section is required.')
)
);
}
}
感谢那些花时间看这个问题的人,尽管我发布了错误的信息。
