Question

当我尝试更新帖子时出现此错误

我想形式上都是正确的，因为我在那里什么都没有改变。

那是我的表单方法：

<form method="post" action="{{ route('games.update', $game->id) }}">
@method('PATCH')
@csrf
</form>

这是我的更新方法：

一切正常，但突然开始出现此错误

public function update(Request $request, $id, Game $game)
{
    if ($game->author !== auth()->user()->id || auth()->user()->cannot('edit games'))
        abort(404);

    $request->validate([
        'title' => 'required',
        'type' => 'required',
        'city' => 'required',
        'district' => 'required',
        'comment' => 'required',
        'full_comment' => 'required',
        'photo' => 'sometimes|mimes:jpeg,jpg,gif,bmp,png',
    ]);

    $game = Game::find($id);
    $game->title = $request->get('title');
    $game->type = $request->get('type');
    $game->city = $request->get('city');
    $game->district = $request->get('district');
    $game->comment = $request->get('comment');
    $game->full_comment = $request->get('full_comment');

    if ($request->has('photo')) {

        $photoName = $game->id . '_photo' . time() . '.' . request()->photo->getClientOriginalExtension();
        $game->photo = $request->get('photo');
        $game->photo = $photoName;
        $request->photo->storeAs('game-photos', $photoName);
    }


    $game->save();

    return redirect('/games')->with('success', 'Game has been  updated');
}

Answer 1

删除第三个形式参数

Game $game

如果您没有在Game模型上实现路线模型绑定

Answer 2

应该这样工作：

public function update(Request $request, $id)
{
    $request->validate([
        'title' => 'required',
        'type' => 'required',
        'city' => 'required',
        'district' => 'required',
        'comment' => 'required',
        'full_comment' => 'required',
        'photo' => 'sometimes|mimes:jpeg,jpg,gif,bmp,png',
    ]);

    $game = Game::find($id);
    $game->title = $request->get('title');
    $game->type = $request->get('type');
    $game->city = $request->get('city');
    $game->district = $request->get('district');
    $game->comment = $request->get('comment');
    $game->full_comment = $request->get('full_comment');

    if ($game->author !== auth()->user()->id || auth()->user()->cannot('edit games')) {
        abort(404);
    }

    if ($request->has('photo')) {
        $photoName = $game->id . '_photo' . time() . '.' . request()->photo->getClientOriginalExtension();
        $game->photo = $request->get('photo');
        $game->photo = $photoName;
        $request->photo->storeAs('game-photos', $photoName);
    }

    $game->save();

    return redirect('/games')->with('success', 'Game has been  updated');
}

函数App \ Http \ Controllers \ MyControllers \ GameController :: update（）的参数太少，传递了2个，恰好期望有3个
