先贴一下模型 ForModel.class.php 代码
<?
class ForModel extends RelationModel{
protected $_link=array(
'Yuangong'=> array(
'mapping_type'=>BELONGS_TO,
'class_name'=>'Yuangong',
'foreign_key'=>'ygid',
'mapping_name'=>'yuangong',
),
);
}
?>再来贴一下调用的Action public function detailed(){
$for=D('For');
$arr =$for->relation('Yuangong')->Select(); //这里关联yuangong表
dump($arr);
exit;
$arr=$for->where("ygid={$_GET['ygid']}")->find();
$this->assign('data',$arr);
$this->display();
}现在的问题是 在Model中去掉mapping_name Action调用时打印$arr出来的数组array(3) {
[0] => array(21) {
["id"] => string(1) "9"
["ygid"] => string(5) "13579"
["fjbgz"] => string(3) "200"
["fglgz"] => string(3) "300"
["fgwjt"] => string(3) "200"
["fgsjt"] => string(3) "200"
["fjxjj"] => string(1) "1"
["fjbf"] => string(2) "30"
["fwcjt"] => string(1) "0"
["fclbt"] => string(1) "0"
["fqqj"] => string(1) "0"
["fgffh"] => string(1) "0"
["fqt"] => string(1) "0"
["kgjj"] => string(1) "0"
["kshbx"] => string(1) "0"
["kgrsds"] => string(1) "0"
["kghf"] => string(1) "0"
["kfk"] => string(1) "0"
["kqqgz"] => string(1) "0"
["kqt"] => string(1) "0"
["Yuangong"] => NULL
} ["Yuangong"] => NULL 这里为空，应该是没有关联上。而如果带着mapping_name，根本没有 ["Yuangong"] => NULL 这一行。 求解决，我想让他们关联起来，好通过ygid获得相对应的yuangong表中的员工姓名字段。应该怎么写，手册看了很多遍也没找到问题所在。
