通过Symfony2依赖注入保留自动完成功能 [英] Preserving auto-completion abilities with Symfony2 Dependency Injection

问题描述

我正在使用PHP Storm作为我的IDE，但是我相信其他IDE(例如Netbeans)将遇到与我将在下面解释的相同的问题.

I'm using PHP Storm as my IDE, but I believe that other IDE's such as Netbeans will have the same issue as I'll explain below.

使用Symfony2之类的框架时，我们添加了精彩的Dependency Injection世界.因此，可以使用下面的代码片段简单地实例化对象:

When using a framework like Symfony2, we have the wonderful world of Dependency Injection added. So objects can simply be instantiated using code like the following snippet:

$myThingy = $this->get('some_cool_service');

这非常方便，因为对象已经预先配置.一个问题是，由于IDE不知道get()方法返回的是哪种类型，因此基本上所有的PHP IDE都将自动完成完全中断.

This is very handy, as objects are already configured beforehand. The one problem is, that auto-completion breaks entirely in basically any PHP IDE, as the IDE does not know what type the get() method is returning.

有没有办法保留自动完成功能?例如，创建Controller的扩展将是答案吗?例如:

Is there a way to preserve auto-completion? Would creating for example an extension of Controller be the answer? For example:

class MyController extends Controller {
    /**
     * @return \MyNamespace\CoolService
     */
    public getSomeCoolService() {
        return new CoolService();
    }
}

然后对于应用程序控制器，将MyController指定为基类而不是Controller?

and then for application controllers, specify MyController as the base class instead of Controller?

使用Factory类或任何其他可能的方法怎么办?

What about using a Factory class, or any other possible methods?

推荐答案

它涉及更多，但是您仍然可以使用Eclipse PDT来做到这一点:

It is more involving, but you can still do this with eclipse PDT:

$myThingy = $this->get('some_cool_service');
/* @var $myThingy \MyNamespace\CoolService */

更新: 此页面上的示例显示，您还可以对phpStorm使用另一种方法:

UPDATE: The example on this page shows you may also use the other way round with phpStorm:

$myThingy = $this->get('some_cool_service');
/* @var \MyNamespace\CoolService $myThingy */
