BadMethodCallException 调用未定义的方法 App\Models\BatterFirst::index()

Question

我想添加一些数据，但我得到了 BadMethodCallException异常调用未定义的方法 App\Models\BatterFirst::index() 错误我的模型 BatterFirst.php 在哪里

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class BatterFirst extends Model
{
    use HasFactory;

    protected $fillable = [
        'name', 'runs', 'balls', 'sixs', 'fours'
    ];
}

这是我的控制器BatterFirstController.php

<?php

namespace App\Http\Controllers;

        ]);

        BatterFirst::create($request->all());

        return redirect()->route('BatterFirst.index')

    }

    }

    /**

    public function update(Request $request, BatterFirst $batterFirst)
    {
        $request->validate([

        return redirect()->route('BatterFirst.index')
                        ->with('success','Batter deleted successfully');
    }
}

这是我的web.php

<?php

use App\Models\BatterFirst;
use Illuminate\Support\Facades\Route;

/*

|
| Here is where you can register web routes for your application. These

|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::resource('BatterFirst', BatterFirst::class);

这是我的 BatterFrist/index.php

这里有什么问题？谢谢你帮助我。如果您需要更详细的代码，请问我，我会更新它。注意：我只是 laravel

的初学者

Answer 1

您必须使用 web.php 中的控制器，而不是模型

use App\Http\Controllers\BatterFirstController;

Route::resource('BatterFirst', [BatterFirstController::class]);

现在您可以从任何地方打电话，例如在 example.blade.php 文件中

<a href={{'BatterFirst.index'}}>Index<a/>

Answer 2

让我们调试您的代码，从请求进入应用程序的地方开始 - 在路由文件中：

Route::resource('BatterFirst', BatterFirst::class);

您有一条 resource() 路线由 BatterFirst::class 处理。但是 class 在哪里？它必须映射到某个东西，如果您查看同一路由文件的顶部，我们会看到：

use App\Models\BatterFirst;

因此 yoursite.com/BatterFirst/ 的请求将由 BatterFirst 模型中的 index() 方法处理。但是当然没有这样的方法。

退后一步，很明显您希望 Controller 来处理您的路由，而不是您的 Model。删除路由文件顶部的 use 行，并将其替换为：

use App\Http\Controllers\BatterFirstController;

并更新要由该控制器处理的路由：

Route::resource('BatterFirst', BatterFirstController::class);
