thinkphp3.2中关联查询
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
------解决思路----------------------
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'=>''
),
);
}
