在Doctrine PHP Symfony中覆盖Doctrine_Record（sfDoctrineRecord）实例方法 [英] Overriding Doctrine_Record (sfDoctrineRecord) instance methods in Doctrine PHP Symfony

问题描述

我的背景是在Propel，所以我希望在Doctrine_Record（sfDoctrineRecord）中覆盖一个魔法吸气剂是一件简单的事情，但是我得到了一个Segfault或者是覆盖方法是被忽略的，有利于一个超类。

https：//gist.github .com / 697008eaf4d7b606286a

  class FaqCategory extends BaseFaqCategory 
 {
 
 public函数__toString（）
 {
 return $ this-> getCategory（）; 
} 
 
 //不工作
 //如果getDisplayName不存在，则覆盖getDisplayName返回到类别名称
 public function getDisplayName（）{
 
 //也尝试了parent :: getDisplayName（）但是得到了segfault（！）
 if（isset（$ this-> display_name））{
 $ display_name = $ this- > DISPLAY_NAME; 
} else {
 $ display_name = $ this-> category; 
} 
 
 return $ display_name; 
 
} 
 
} 
  

适当的Doctrine方式来扩展/覆盖Doctrine_Record实例（通过sfDoctrineRecord扩展Doctrine_Record）的方法？这必须是可行的，或者我应该看模板文档？

谢谢，
Brian

解决方案

尝试_get和_set方法。

My background is in Propel, so I was hoping it would be a simple thing to override a magical getter in a Doctrine_Record (sfDoctrineRecord), but I'm getting either a Segfault or the override method is simply ignored in favor of the one in the superclass.

https://gist.github.com/697008eaf4d7b606286a

class FaqCategory extends BaseFaqCategory
{

  public function __toString()
  {
    return $this->getCategory();
  }

  // doesn't work
  // override getDisplayName to fall back to category name if getDisplayName doesn't exist
  public function getDisplayName() {

    // also tried parent::getDisplayName() but got segfault(!)
    if(isset($this->display_name)) {
      $display_name = $this->display_name;
    } else {
      $display_name = $this->category;
    }

    return $display_name;

  }

}

What is the proper Doctrine way to extend/override methods on an instance of Doctrine_Record (via sfDoctrineRecord extends Doctrine_Record)? This has to be doable...or should I be looking at the Template documentation?

Thanks, Brian

解决方案

Try _get and _set methods.
