在 Doctrine PHP Symfony 中覆盖 Doctrine_Record (sfDoctrineRecord) 实例方法

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

问题描述

我的背景是 Propel，所以我希望在 Doctrine_Record (sfDoctrineRecord) 中覆盖一个神奇的 getter 是一件简单的事情，但是我得到了一个 Segfault 或者覆盖方法被简单地忽略了超类中的一个.

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.

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;

  }

}

在 Doctrine_Record 实例上扩展/覆盖方法的正确 Doctrine 方法是什么(通过 sfDoctrineRecord 扩展 Doctrine_Record)?这必须是可行的...还是我应该查看模板文档?

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?

谢谢，布赖恩

推荐答案

试试 _get 和 _set 方法.

Try _get and _set methods.
