問題描述
在我的 Laravel 應用程序中，我有一個 Faq 模型.一個 Faq 模型可以包含多個 Product 模型，所以 Faq 類包含以下函數:
In my Laravel application I have an Faq model. An Faq model can contain many Product models, so the Faq class contains the following function:
class Faq extends Eloquent{
public function products(){
return $this->belongsToMany('Product');
}
}
在控制器中，我希望能夠檢索定義關系的類名.例如，如果我有一個 Faq 對象，如下所示:
In a controller, I would like to be able to retrieve the class name that defines the relationship. For example, if I have an Faq object, like this:
$faq = new Faq();
如何確定關系的類名，在本例中為 Product.目前我可以這樣做:
How can I determine the class name of the relationship, which in this case would be Product. Currently I am able to do it like this:
$className = get_class($faq->products()->get()->first());
但是，我想知道是否有一種方法可以在無需實際運行查詢的情況下完成同樣的事情.
However, I'm wondering if there is a way to accomplish this same thing without having to actually run a query.
推薦答案
是的，有一種不用查詢就可以得到相關模型的方法:
Yes, there is a way to get related model without query:
$className = get_class($faq->products()->getRelated());
它適用于所有關系.
這將返回帶有命名空間的全名.如果您只想使用基本名稱:
This will return full name with namespace. In case you want just base name use:
// laravel helper:
$baseClass = class_basename($className);
// generic solution
$reflection = new ReflectionClass($className);
$reflection->getShortName();
