[路由：BatterFirst.update] [URI：BatterFirst/{BatterFirst}] [缺少参数：BatterFirst] 缺少必需的参数。 edit.blade.php)

Question

当我在做 laravel CRUD 项目时，我得到了 .我在这里停留了 2 天

Illuminate\Routing\Exceptions\UrlGenerationException [路由：BatterFirst.update] [URI：BatterFirst/{BatterFirst}] [缺少参数：BatterFirst] 缺少必需参数。（查看：C:\xampp\htdocs\CricBangla\resources\views\BatterFirst\edit.blade.php）错误。

我找不到错误所在。

这是我的 web.php

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

这是我的模型BatterFirst.php

class BatterFirst extends Model
{
    use HasFactory;
    protected $table = 'batterfirst';

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

这是我的BatterFirstController.php

<?php

namespace App\Http\Controllers;

use App\Models\BatterFirst;
use Illuminate\Http\Request;

class BatterFirstController extends Controller
{
    public function index()
    {
        $data = BatterFirst::latest()->paginate(5);

        return view('BatterFirst.index',compact('data'))
            ->with('i', (request()->input('page', 1) - 1) * 5);
    }

    public function create()
    {
        return view('BatterFirst.create');
    }

    public function store(Request $request)
    {
        $request->validate([
            'name' => 'required',
            'runs' => 'required',
            'balls' => 'required',
            'sixs' => 'required',
            'fours' => 'required',
        ]);

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

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

    public function show(BatterFirst $batterFirst)
    {
        return view('BatterFirst.show',compact('batterFirst'));
    }

    public function edit(BatterFirst $batterFirst)
    {
        return view('BatterFirst.edit',compact('batterFirst'));
    }

    public function update(Request $request, BatterFirst $batterFirst)
    {
        $request->validate([
            'name' => 'required',
            'runs' => 'required',
            'balls' => 'required',
            'sixs' => 'required',
            'fours' => 'required',
        ]);

        $batterFirst->update($request->all());

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

    public function destroy(BatterFirst $batterFirst)
    {
        $batterFirst->delete();

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

这是我的编辑。blade.php

注：刚开始学习laravel。谢谢

Answer 1

尝试删除方法POST。更新将使用 PUT 作为方法。

  <form action="{{ route('BatterFirst.update',$batterFirst->id) }}" method="POST">
        @csrf
        @method('PUT')

然后在你的路由函数中改变这个。在数组中传递 id。

"{{route('BatterFirst.update',['id' => $batterFirst->id])}}"

然后会这样:

  <form action="{{ route('BatterFirst.update',['id' => $batterFirst->id]) }}" method="PUT">
        @csrf
        @method('PUT')
