CREATE TABLE `test_avatar` ( `uid` int(11) unsigned NOT NULL DEFAULT '0', `avatar` varchar(255) NOT NULL DEFAULT '', PRIMARY KEY (`uid`)) ENGINE=MyISAM DEFAULT CHARSET=utf8;INSERT INTO `test_avatar` VALUES (1,'./Uploads/admin.jpg');CREATE TABLE `test_pro` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `uid` int(11) unsigned NOT NULL DEFAULT '0', `name` varchar(255) NOT NULL DEFAULT '', PRIMARY KEY (`id`)) ENGINE=MyISAM DEFAULT CHARSET=utf8;INSERT INTO `test_pro` VALUES (1,1,'产品1'),(2,1,'产品2');CREATE TABLE `test_user` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `username` varchar(50) NOT NULL DEFAULT '', `tel` int(11) unsigned NOT NULL DEFAULT '0', PRIMARY KEY (`id`)) ENGINE=MyISAM DEFAULT CHARSET=utf8;INSERT INTO `test_user` VALUES (1,'admin',110);
如上三个表:用户头像表、产品表、用户表
怎样在模型中建立关联?
class ProModel extends RelationModel{ protected $_link=array( 'Avatar'=>array( 'mapping_type'=>self::HAS_ONE, 'class_name'=>'Avatar', 'foreign_key'=>'uid', 'mapping_fields'=>'avatar', 'as_fields'=>'avatar', ), )}
试过用HAS_ONE、BELONGS_TO、HAS_MANY、MANY_TO_MANY都不行,求大神指点
回复讨论(解决方案)
Model下建立ProModelModel.class.php
class ProModelModel extends ViewModel { public $viewFields = array( 'test_avatar'=>array( 'id',... ), 'test_pror'=>array( 'id',... '_on'=>'' ), 'test_pror'=>array( 'id',... '_on'=>'' ), ); }
