在Laravel中动态使用模型 [英] Dynamically use model in laravel

问题描述

在我的laravel项目中，我创建了一个控制器，用于从所有调用同一个控制器的刀片中删除该项目，并传递动态ID和型号名称.但显示未找到类的错误. 例如:找不到用户"类.

In my laravel project I create a controller for delete the item from all the blade call the same controller.With passing dynamic id and model name. but showing an error for class not found. ex: Class 'User' not found.

如何添加使用用户；动态代码在我的控制器中.

How can I add use User; code in my controller dynamically.

namespace App\Http\Controllers;
use Illuminate\Http\Request;
class AjaxController extends Controller
{
    public function deleteItem(Request $req)
    {
        use $req['model'];
        $id = $req['id'];
        $model_name = $req['model'];
        $mdoel_name = $model_name::find($id);
        $mdoel_name->delete();
        sactivity('delete')->performedOn($mdoel_name)->log('');
        return "success";
    }
}

推荐答案

这应该有效:

    $id = $req['id'];
    $model_name = '\\App\\'.$req['model'];
    $model = new $model_name;
    $model_name = $model->find($id);
    $model->delete();
    sactivity('delete')->performedOn($model_name)->log('');
    return "success";
