Php Laravel更新如何更新索引中的数据

问题是我想跳过那个编辑页面。它也很好用。但我想在索引视图中编辑我的数据

我尝试了此操作，但出现了此错误

{!! Form::model($choice, ['method' => 'PATCH','route' => ['choices.update', $choice->id]]) !!}
  <input class="form-control" value="@foreach ($choices as $choice){{ $choice->question_number }}@endforeach" type="number" name="number"></input>
{!! Form::submit('Update Task', ['class' => 'btn btn-primary']) !!}
{!! Form::close() !!}

---

获取对象属性时，必须始终检查对象是否存在

@if (!empty($duplicate->topic))
    <td><a href="{{ route('choices.edit', $duplicate->topic->id) }}" class="btn btn-default">Edit</a></td>
@endIf

---

将

$choice

更改为另一个名称，例如

$\u choice

，为避免混淆上面使用的

$choice

请在单击编辑时使用模式。我忘了莫代尔。你能提供一个很好的例子吗？为什么你在modalI中应用foreach的值，你认为你已经在

{{{$choice->question\u number}}

中得到了这个问题的编号……你是否检查了$choice，$duplicate->topic empty？？

{!! Form::model($choice, ['method' => 'PATCH','route' => ['choices.update', $choice->id]]) !!}
    <input class="form-control" type="number" name="number"></input>
{!! Form::submit('Update Task', ['class' => 'btn btn-primary']) !!}
{!! Form::close() !!}

public function update(Request $request,Choice $choice){
     Choice::where('id', $choice->id)->update([
        'question_number' => $request->input('number')
        ]);
  return redirect()->route('choices.index');
}

@if (!empty($duplicate->topic))
    <td><a href="{{ route('choices.edit', $duplicate->topic->id) }}" class="btn btn-default">Edit</a></td>
@endIf

@if (!empty($choice))
    {!! Form::model($choice, ['method' => 'PATCH','route' => ['choices.update', $choice->id]]) !!}
        <input class="form-control" type="number" name="number"></input>
    {!! Form::submit('Update Task', ['class' => 'btn btn-primary']) !!}
    {!! Form::close() !!}
@endIf

@foreach ($choices as $choice){{ $choice->question_number }}@endforeach
