我是Cake用户的开始，但是精通php和框架工作（我以前使用Code Igniter）。如何调用下面的模型，只返回艺术家记录和相关的ArtistImage记录，而不是相册记录。
class Artist extends AppModel {
var $name = 'Artist';
var $hasMany = array('Album', 'ArtistImage');
}
另外，你能澄清一下$ this-Artist-＆gt;递归的值吗？
感谢您的帮助

// Artist /app/models/artist.php
class Artist extends AppModel {
var $name = 'Artist';
var $hasMany = array('Album', 'ArtistImage');
var $actAs = array('Containable');
}
// ArtistsController /app/controllers/artists_controller.php
class ArtistsController extends AppController {
var $name = 'Artists';
public function example() {
debug( $this->Artist->find( 'all' );
debug( $this->Artist->find( 'all', array(
'recursive' => 0,
));
debug( $this->Artist->find( 'all', array(
'contain' => array(
'ArtistImage' => array(
// artist find options here i.e. fields, conditions, order etc
),
);
));
}
}
// results
// with just find( 'all' )

希望有助于解释它

我认为问题在于你的艺术家模特。添加行为的正确方法是
<?php
Class Artist extends AppModel
{
public $name = "Artist";
public $actsAs = array( 'Containable' );
}
?>
注意actsAs变量是复数，你的模型将它作为$ actAs = array（..），变量为单数。

您正在寻找可包含的行为（book.cakephp.org/view/474/Containable）。
递归属性（book.cakephp.org/view/439/recursive）告诉我们在获取记录时CakePHP应该在关系方面有多深。

您可以将控制器和型号发布到pastebin中吗？你完成后在这里发布这些链接。
在您使用的pastebin条目中......
if( $images ) {
echo( "Loading Artist Images" );
$this->Artists->recursive = 1;
$this->Artists->contains( 'ArtistImage' );
} else { ...
由于一些原因，这不会起作用。
首先 - 模型名称必须是单数。 I.E.艺术家=艺术家 第二 - Containable行为没有函数“contains”，正确的函数名也是单数。 I.E包含（'ArtistImage'）= contains（'ArtistImage'）
所以我FTFY，你走了。
if( $images ) {
echo( "Loading Artist Images" );
$this->Artist->contain( 'ArtistImage' );
} else { ...
希望这能为您澄清一些事情。 http://book.cakephp.org/view/474/Containable http://book.cakephp.org/view/22/CakePHP-Conventions
此外，根据您使用的Cake版本，我相信调用不存在的模型函数（即Model-＆gt; contains（...））将尝试从mysql调用存储过程文件没有该名称的功能。

模特是专辑，所以它应该是$ this-＆gt;专辑而不是$ this-＆gt;专辑
App :: import（'Model'，'Album'）;
$这 - ＆GT;相册 - ＆GT;包含（ '宋'）; $ items = $ this-＆gt;相册 - ＆gt; findAllByArtistId（$ artist_id）;
