thinkphp中的关联模型问题

[山贼一名]

在模型里面定义了一个ManagersModel类，如下所示

protected $_link=array(
			'roles'=>array(
			
				'mapping_type'=>MANY_TO_MANY,

                'foreign_key'=>'ryxh',

                'relation_foreign_key'=>'jsxh',

                'relation_table'=>'etch_role_manages',
				
		'as_fields'=>'jsmc',
				
			),
			
		);

用以下方法操作

public function test(){
			$Role_manages=D("Managers");
			$data=$Role_manages->relation(true)->find(1);
			echo "<pre>";
			print_r($data);
			
			echo $data['roles'][0]['jsmc'];
		}

返回的是
Array
(
[ryxh] => 1
[sjbh] => 900
[ryzh] => 900001
[ryxm] => 卢XIAO哲GGG
[rymm] => c3949ba59abbe56
[sjhm] => 13333333333
[dzyj] => [e-mail]
[yzhm] => 4567
[yxqx] => 2147483647
[cjsj] => 2147483647
[cssj] => 2147483647
[csip] => 12.34.56.78
[zfpb] => 0
[ssbm] => 门店
[szdz] => 蒋村花园行大院
[zd1] =>
[zd2] =>
[zd3] =>
[roles] => Array
(
[0] => Array
(
[jsxh] => 1
[jsmc] => 管理员
[bz] => 测试
[jsjb] => 1
[zfpb] => 0
[sssj] => 900
)

)

)
相当于'as_fields'=>'jsmc'没起作用，另外为什么返回的role里的元素为什么还是个数组
求各位大侠解答啊，万分感谢

关联模型兼容性不是很好，特别注意大小写

'relation_table'=>'etch_role_manages',

改为Etch_role_manages

唉，还是一样。不过谢谢

'as_fields这个特性是ONE_TO_ONE 关联特有的
