laravel:模型中的函数必须返回一个关系实例 [英] laravel: function in model must return a relationship instance

问题描述

我尝试在laravel上为模型建立路径

I try to build a path for a model on laravel

我在模型中创建了一个函数:

I created a function in my model:

public function path()
{
    return App\Helper\GeneralController::getURL($this);
}

通过dd(App\Helper\GeneralController::getURL($this))测试，我得到了正确的答案. (输出是一个URL)

with dd(App\Helper\GeneralController::getURL($this)) test I got the right answer. (output is a URL)

但在通话中:$article->path我收到此错误:

but in view with the call: $article->path I get this error:

App\Article:: path must return a relationship instance.

怎么了?

推荐答案

您需要调用它:

$article->path()

当您执行$article->path时，您正在尝试使用没有的口才关系.

When you do $article->path, you're trying to use Eloquent relationship which you don't have.
