使用Laravel更新对象

Question

我想更新“指定”的值，但是当我点击第一项时，表单会自动填充插入的最后一个值，而不是我点击的那个，
例如，如果我想更新“ FM2 ”的值，我会在表格中得到“ tst ”：

这是视图代码：

    @extends('dashboard.layout')

@section('title' , 'Manage Sockets')
@section('pageHeader', 'Sockets')

@section('content')

    <div class="card">

        <div class="table-responsive">
            <table id="data-table-basic" class="table table-striped">
                <thead>
                <tr>
                    <th data-column-id="id" data-type="numeric">ID</th>
                    <th data-column-id="sender">Designation</th>
                    <th data-column-id="received" data-order="desc">Updated on</th>
                    <th data-column-id="operations" data-order="desc">Operations</th>
                </tr>
                </thead>
                <tbody>
                    @foreach($sockets as $socket)
                        <tr>
                            <td>{{$socket->id}}</td>
                            <td>{{$socket->designation}}</td>
                            <td>{{$socket->updated_at}}</td>
                            <td>
                                <a href="{{action('SocketController@delete', ['id' =>$socket->id ])}}" class="btn bgm-cyan waves-effect"><i class="zmdi zmdi-close"></i></a>
                                <a data-toggle="modal" href="#modalDefault"  class="btn bgm-orange waves-effect"><i class="zmdi zmdi-edit"></i></a>
                            </td>

                        </tr>
                    @endforeach
                </tbody>
            </table>

        </div>

@endsection

我该如何解决这个问题？

Answer 1

在您的代码中，您必须为每条记录单独设置所有模型，这是不可取的 要么 您可以通过jquery点击动态更改引导模式的内容和路由参数ID，否则它只会在您设置它时获取最后输入的记录ID。 所以 变化

GeoJSON

到

{!! Form::model($socket,['route' =>['socketupdate',$socket->id],'method'=>'POST']) !!}

并在编辑按钮上单击替换rep_id。
