【问题描述】：
我正在尝试用点更新表格。我想用livewire点击一下，但没有任何效果，所以我认为只使用我已经拥有的Laravel控制器中的方法会更容易。之所以使用附加和分离，是因为我的视图中有两个表，一个包含所有站点，另一个包含我正在尝试更新的站点，其中包含已经在工作簿中的站点。以我现在的方法，我可以更新除现场之外的所有内容，但我不知道为什么。工作簿和站点之间是多对多的关系，并且点是数据透视表中的一个额外字段。
<form action="{{route('admin.workbooks.update', [$client_id, $workbook_id])}}" method="POST" enctype="multipart/form-data">

<div class="form-group">
<label for="">Media Schedule Name</label>
<input type="text" class="form-control" name="wrkb_name" value="{{$workbook_name}}">

<table class="table-auto w-full mb-6">

</form>
public function update(UpdateWorkbookRequest $request,Client $client, Workbook $workbook)
{
$workbook->update($request->only('wrkb_name'));
$workbook->stations()->detach($request->input('selected_stations', []));
$workbook->stations()->attach($request->input('stations', []));
$workbook->stations()->updateExistingPivot('spot', []);
return redirect()->route('admin.workbooks.edit', [$client->id, $workbook->id])->with('success', 'Successfully Edited the Workbook');
}
这就是其中一种关系的样子，尽管我认为这没有多大帮助
public function workbooks()
{
return $this->belongsToMany(\App\Models\Workbook::class, 'station_workbook', 'station_id', 'workbook_id')->withPivot('spot')->withTimestamps();;
}
我还发现我可以使用类似的东西，但我只想更新那个特定的记录，从这段代码看来，它似乎更新了该站的每个实例，不管是什么工作簿，但无论如何它都不起作用。
foreach($workbook->stations as $key => $station){
dd($station->workbooks);
$station->workbooks()->updateExistingPivot($key, ['spot' => $request ->spot]);
}
我也试过了，没有成功
$usedStations=$request->input('stations', []);
$workbook->update($request->only('wrkb_name'));
$workbook->stations()->detach($request->input('selected_stations', []));
$workbook->stations()->attach($request->input('stations', []));
foreach($usedStations as $usedStation)
{
$station_id = Station::where('id',$usedStation)->value('id');
$workbook->stations()->updateExistingPivot($station_id, ['spot' => $request ->spot]);
}
