我在模型类中做了一个函数

i made a function into model class which is

public function scopetest($query)
    {
 return $query->pluck('name');
    }
  }

我的控制器代码是

 public function index()
     {
     $books = Book::all();

     return view('welcome',compact('books'));

       }

要获取我编写的视图文件的test()函数结果

推荐答案

有很多方法可以在视图中调用模型函数.

There are many ways to call a model function in the view.

方法1:

传递一些模态以在您的控制器中查看，例如:

Pass Some Modal to view in your controller like :

$model = Model::find(1);
View::make('view')->withModel($model);

在模式中创建一些函数:

In modal create a some function:

  public function someFunction() {
   // do something
  }

在视图中，您可以直接通过以下方式调用此函数:

In view you can call this function directly as:

{{$model->someFunction()}}

方法2或其他方式:

您可以在模型中创建静态函数，例如:

You can make a static function in the model like:

public static function someStaticFunction($par1, $par2) {
   // do what you need
}

在您看来，您可以直接将功能建模为:

And in your view you can model function directly as:

{{App\Model::someStaticFunction($par1,$par2)}}
