Laravel: Controllerのstoreメソッドの引数にはRequestをつけよう

Posted at

はじめに

Laravel6を用いて、商品のいいね機能を実装していました。
その際、1時間もつまづいたエラーがありました。

Too few arguments to function App\Http\Controllers\User\Product\RateController::store(), 1 passed in /var/www/ec_Laravel/vendor/laravel/framework/src/Illuminate/Routing/Controller.php on line 54 and exactly 2 expected

こちらは、「引数が足りていないよ」みたいな感じのエラーでした。

修正前コード

web.php
// 中略
Route::resource('user/product/{product_id}/rate', 'User\Product\RateController', ['only' => ['store', 'update', 'destroy']]);
show.blade.php
<form method="POST" action="{{ route('rate.store', $product->product_id)}}">
    @csrf
        <input type="hidden" name="rate_type" value="1">
        <button type="submit">提出</button>
</form>
RateContoroller.php
public function store($product_id, $request)
{
    // ここでエラーが発生


    Rate::create([
        'rate_type' => $request->rate_type,
        'user_id' => Auth::id(),
        'product_id' => $product_id,
    ]);
    
    return redirect()->back();
}

普通にproduct_idrequestをPOSTメソッドで渡しているんだが???

これで1時間ぐらい悩まされました。

解決方法

RateContoroller.php
use Illuminate\Http\Request;

public function store($product_id, Request $request)
{
    Rate::create([
        'rate_type' => $request->rate_type,
        'user_id' => Auth::id(),
        'product_id' => $product_id,
    ]);

    return redirect()->back();
}

なんとstoreメソッドの$requestの前にRequestをつければ解決できました。

公式ドキュメントをちゃんと読みましょう...
