【问题描述】：
我无法弄清楚为什么我的关联不起作用。
我得到的错误如下：
Fatal error: Call to a member function add() on a non-object in http://localhost/Projects/clariture/app/src/Clariture/Models/Channel.php on line 32
我的代码如下：
<?php
namespace Clariture\Classes;
class Entity {
/**
* @Id @Column(type="integer")
* @GeneratedValue
*/
protected $id;
/**
* @Column(type="integer")
*/
protected $dateCreated = 0;
/**
* @Column(type="integer")
*/
protected $dateUpdated = 0;
/**
* @param string $name
*/
public function __get($name)
{
return $this->$name;
}
/**
* @param string $name
* @param mixed $value
*/
public function __set($name, $value) {
$this->$name = $value;
}
}
<?

-
异常在第 32 行的
Clariture\Models\Channel中指出错误，但您没有将此类添加到您的问题中。你想做什么？坚持一个新实体？更新现有的？请提供更多信息。 -
抱歉，添加了那个类:)
-
奇怪的活动记录模式顺便说一句。 - 你确定你知道你在那里做什么吗？无论如何，我的回答应该可以解决您的问题:)
-
怪异？你能详细说明一下吗？
-
请不要误会我的意思——我只是想帮忙 :) “怪异”的目标是你的代码风格——没有设置器，奇怪的对象实例化链，混合 php 5.4 风格 @987654324 @ 和旧的
array()语法在这里和那里......看起来很混合，并且带有教义的活动记录模式并不那么容易实现。
