如何在模型中获取 Symfony 会话变量? [英] How to get Symfony session variable in model?

问题描述

如何在不使用 sfContext::getInstance() 的情况下在 symfony 模型中传递会话变量?

How can I pass session variable in symfony model without using sfContext::getInstance()?

推荐答案

推荐的方式称为依赖注入，其工作方式如下:您在模型文件中创建一个 setUser() 方法，即将给定的参数保存到私有属性:

The recommended way is called dependency injection, and works like this: you create a setUser() method in your model file, that saves the given parameter to a private property:

class Foo {
  private $_user;

  public function setUser(myUser $user) {
    $this->_user = $user;
  }

  // ... later:

  public function save(Doctrine_Connection $conn = null) {
    // use $this->_user to whatever you need
  }
}

这看起来很笨拙，因为它是.但是如果你不回答这个问题你想做什么?我不能给出替代方案.

This looks clumsy, because it is. But without you answering the question what are you trying to do? I cannot give an alternative.
