PHP ActiveRecord - 关联不起作用

Question

我刚刚开始使用 PHP ActiveRecord 类，并且相处得很好，但现在我被尝试将一个用户与一个组以及一个与许多用户关联的组所困扰。

这就是我所拥有的:

SQL 部分:

CREATE TABLE `users` (
      `id`          INT(255)        NOT NULL AUTO_INCREMENT,
      `group_id`    INT(255)        NOT NULL ,
      `name`        VARCHAR(150)    NOT NULL ,
      `email`       VARCHAR (150)   NOT NULL ,
      `passwd`      VARCHAR (512)   NOT NULL ,
      `salt`        VARCHAR (16)   NOT NULL ,
      PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

CREATE TABLE `groups` (
      `id`          INT(255)        NOT NULL AUTO_INCREMENT,
      `name`        VARCHAR(150)    NOT NULL ,
      PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

PHP 类:

#Class User.php
class User extends ActiveRecord\Model{

    static $belongs_to = array(
        array('group')
    );

    static $validates_presence_of = array(
        array('name'),
        array('email'),
        array('passwd'),
        array('salt')
    );

    static $validates_uniqueness_of = array(
        array('name'),
        array('email')
    );
}

#Class Group.php
class Group extends ActiveRecord\Model{

    static $has_many = array(
        array('users')
    );

    static $validates_presence_of = array(
        array('name')
    );

    static $validates_uniqueness_of = array(
        array('name')
    );
}

VAR 转储用户:

<?php
    var_dump(User::find(1));
?>

现在，如果我搜索用户，则不会附加任何组...有人知道如何解决此问题或者可以告诉我我做错了什么吗？我只是找不到我的错误...:)

var_dump 输出:

object(User)[32]
  public 'errors' => null
  private 'attributes' (ActiveRecord\Model) => 
    array (size=6)
      'id' => int 1
      'group_id' => int 1
      'name' => string 'admin' (length=5)
      'email' => string 'user@email.com' (length=17)
      'passwd' => string 'f22b07f3b0f2d93a696336f040a6d08b8c36fe53fc5f080b5a3ad1db3387b4553f16ed2c7c4196900f3ff9b8aa516b115e8250be6c0a60f6e22cf768fe43c291' (length=128)
      'salt' => string '6976e5b5410415bd' (length=16)
  private '__dirty' (ActiveRecord\Model) => 
    array (size=0)
      empty
  private '__readonly' (ActiveRecord\Model) => boolean false
  private '__relationships' (ActiveRecord\Model) => 
    array (size=0)
      empty
  private '__new_record' (ActiveRecord\Model) => boolean false

无论如何，感谢您查看它:)

采取了解决方法:

<?php
class Model extends ActiveRecord\Model{

    public $Extensions = array();
    protected $relations = array('has_one' => array(), 'belongs_to' => array());

    static $after_construct = array('set_relations');

    public function set_relations(){
        foreach($this->relations['has_one'] as $relation){
            $upper =  ucfirst($relation);
            $lower = strtolower($relation);
            $id_table = $lower.'_id';

            $this->Extensions[$upper] = $upper::find($this->$id_table);
        }

        foreach($this->relations['belongs_to'] as $relation){
            $model =  ucfirst($relation[0]);
            $id_table = $relation[1];

            $this->Extensions[$model] = $model::find(array('conditions' => array($id_table.' = ?', $this->id)));
        }
    }
}

这就是你如何使用它......

    protected $relations = array('has_one' => array('group'), 'belongs_to' => array(array('publisher', 'user_id')));

    static $validates_presence_of = array(
        array('name'),
        array('email'),
        array('passwd'),
        array('salt'),
        array('group_id')
    );

    static $validates_uniqueness_of = array(
        array('name'),
        array('email')
    );
}
?>
