Laravel雄辩:更新父记录并使用一种形式在另一个表中创建新记录

我有两个表,分别为machinescallsmachines表包含计算机及其详细信息的列表。当前,要记录有关机器的故障呼叫,管理员将输入machine_number(以确保机器已在公司下注册)。此数字用于搜索数据库中的machines表,结果将以表格形式显示。

我的问题是我希望遇到一种情况,即在提交表单时,在创建新行时,machines表中计算机的详细信息将被更新(以防更改详细信息)。 calls表中(以记录故障呼叫)。

以下是搜索功能:

Route::any('/search_results',function(){
    $query = Input::get ( 'query' );
    $machine= Machine::where('machine_id','LIKE','%'.$query.'%')->get();
    return view('/addNewCall')->with('machine', $machine)->withQuery($query);
});

这是我的表格:

<form action="{{route('Call.store')}}" method="POST">
    @csrf
    @if(count($machine) > 0)
        @foreach($machine as $machine)
            <div class="col-md-6">
                <div class="input-group" style="width: 100%;">
                    <label for="machine_id">{{ __('Machine ID') }}</label><br>
                    <input type="text" name="machine_id" id="machine_id" class="form-control" style="padding: 20px;" value="{{$machine->machine_id}}">
                </div>
            </div>
            <div class="col-md-6" style="margin-top:20px">
                <div class="input-group col-md-12" style="width: 100%;">
                    <label for="machine_custodian">{{ __('Machine Custodian Name') }}</label><br>
                    <input type="text" name="machine_custodian" id="machine_custodian" class="form-control" style="padding: 20px;" value="{{$machine->machine_custodian}}" required>
                </div>
            </div>
            <div class="col-md-6" style="margin-top:20px">
                <div class="input-group" style="width: 100%;">
                    <label for="call_logged_on">{{ __('Call logged on') }}</label><br>
                    <input type="datetime-local" name="call_logged_on" id="call_logged_on" class="form-control" style="padding: 20px;" required>
                </div>
            </div>
            <div class="input-group col-xs-12 form-group" style="margin-top:20px">
                <label for="fault_description">{{ __('Fault Description') }}</label><br>
                <textarea name="fault_description" id="fault_description" class="form-control" rows="7" cols="50"  required></textarea>
            </div>
            <div class="col-md-6">
                <div class="input-group" style="width: 100%;">
                    <label for="assigned_FE">{{ __('Field engineer in charge') }}</label><br>
                    <input type="text" name="assigned_FE" id="assigned_FE" class="form-control" style="padding: 20px;" value="{{$machine->assigned_FE}}" required>
                </div>
            </div>
        @endforeach
        <button type="submit" class="btn-primary" style="padding: 10px; font-size: 16px; border: 0; margin-top:25px">{{ __('Log 
        Call') }}</button>
    @else
        <h2 style="margin:30px; font-style:italic; font-weight:lighter" class="text-center">Sorry, there is no ATM with the terminal id of "<b>{{ $query }}</b>" in our database</h2>
    @endif
</form>

这是我的CallsController:

public function store(Request $request)
{
    $this->validate($request,[
        'machine_id' => 'required',
        'machine_custodian' => 'required',
        'call_logged_on' => 'required',
        'fault_description' => 'required',
        'assigned_FE' => 'required',
    ]);
        //store in the database
    $call = new Call;
    $call->machine_id = $request->input('machine_id');
    $call->machine_custodian = $request->input('machine_custodian');
    $call->call_logged_on = $request->input('call_logged_on');
    $call->fault_description = $request->input('fault_description');
    $call->assigned_FE = $request->input('assigned_FE');
    $call->save();

    return redirect('/pages/newCall')->with('success', 'call created check pending calls to view call');
}

当前,代码在calls表中创建一个新行。但是我不知道如何增强代码来更新machines表中的机器信息。

注意:machine_id列与id表中的machines列不同

答案 0 :(得分:1)

在return语句之前,您可以通过id获取“机器”对象,并使用update()方法更新所需的列:

$machine = Machine::find($call->machine_id);
$machine->update(['machine_custodian'=>$call->machine_custodian, 'assigned_FE'=>$call->assigned_FE]);

也可能是:

$machine = Machine::find($call->machine_id);
$machine->machine_custodian = $call->machine_custodian;
$machine->assigned_FE = $call->assigned_FE;
$machine->save();
