【问题描述】：

我有一个问题，但没有找到解决方案。

显示以下故障：

Facade\Ignition\Exceptions\ViewException [Route: settings.networks.update] [URI: settings/networks/{network}] 缺少必需的参数。（查看：C:\xampp\htdocs\patom\layout\resources\views\settings\networks\edit.blade.php） http://localhost:8000/settings/networks/5/edit

我的控制器：

/**
 * Show the form for editing the specified resource.
 *
 * @param  \App\Network  $network
 * @return \Illuminate\Http\Response
 */
public function edit($id)
{
    $network = Network::find($id);

    return view('settings.networks.edit', compact('network'));
}

我的编辑：

@extends('layouts.dashboard')

@section('content')

<!-- Content Wrapper. Contains page content -->
 <div class="content-wrapper">
   <!-- Content Header (Page header) -->

       <!-- /.col -->
     </div>
     <!-- /.row -->
   </section>
   <!-- /.content -->
 </div>

@endsection

我的索引：

|@foreach($networks as $network)

           <tr>
             <td>{{ $network->id }}</td>
             <td>{{ $network->name }}</td>
             <td><div class="btn-toolbar pull-right">
                  <a href="{{ route('settings.networks.edit', $network->id) }}"><button type="button" class="btn btn-success mr-3">Edit</button></a>
                 <form action="{{ route('settings.networks.destroy', $network->id) }}" method="POST">
                   @csrf
                   {{ method_field('DELETE') }}
                    <button type="submit" class="btn btn-danger mr-3">Delete</button>
                  </form>
                 </div>
             </td>
           </tr>

          @endforeach

我的路线：

Route::namespace('Settings')->prefix('settings')->name('settings.')->group(function(){

Route::resource('/networks', 'NetworksController', ['except' => ['show']]);

});

【解决方案1】：

当你把路由放到视图文件中时，你仍然需要包含模型来生成路由。

您的视图中有一条这样的路线，但它缺少网络模型。

{{ route('settings.networks.update') }}

您已经包含了网络，所以添加它应该很简单。

{{ route('settings.networks.update', ['network' => $network]) }}
