好吧，所以我所做的是一个应用程序，它消耗存储中的 json 文件并将它们作为项目放入洗碗机的数据库中。 json 处理和使用都很顺利，除了编辑数据库中的当前项目之外，所有路由都很好： DeviceController 的代码在这里：
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Device;
use App\Models\DetergentPump;
use Illuminate\Support\Facades\File;
use Illuminate\Support\Facades\Storage;
class DeviceController extends Controller
{
public function processJsonFile(Request $request)
{
$jsonFiles = Storage::files('json');
foreach ($jsonFiles as $jsonFile) {
if(Storage::exists($jsonFile)){
$jsonContent = json_decode(Storage::get($jsonFile), true);
// Process and store the data
$device = Device::create([
'device_id' => $jsonContent['device_id'],
'location_name' => $jsonContent['location_name'],
]);
foreach ($jsonContent['detergent_pumps'] as $pumpData) {
DetergentPump::create([
'device_id' => $device->device_id,
'name' => $pumpData['name'],
'active' => $pumpData['active'],
'trigger' => $pumpData['trigger'],
'dosage' => $pumpData['dosage'],
'xp' => $pumpData['xp'],
'xt' => $pumpData['xt'],
'total' => $pumpData['total'],
'remaining' => $pumpData['remaining'],
]);
}
dd("1");
return redirect('/devices')->with('success', 'Data processed and stored successfully.');
} else {
dd("2");
return redirect('/devices')->with('error', 'JSON file not found.');
}
}
return redirect('/devices')->with('success', 'All JSON files processed and stored successfully.');
}
public function index()
{
$devices = Device::all();
return view('devices.index', compact('devices'));
}
public function show($id)
{
$device = Device::findOrFail($id);
return view('devices.show', compact('device'));
}
public function create()
{
return view('devices.create');
}
public function store(Request $request)
{
$request->validate([
'device_id' => 'required|unique:devices',
'location_name' => 'required',
]);
Device::create($request->all());
return redirect('/devices')->with('success', 'Device created successfully.');
}
public function edit($id)
{
$device = Device::findOrFail($id);
return view('devices.edit', compact('device'));
}
public function update(Request $request, Device $device)
{
// dd('Before validation', $request->all());
$request->validate([
'location_name' => 'required',
'detergent_pumps' => 'required|array',
'detergent_pumps.*.name' => 'required|string',
'detergent_pumps.*.dosage' => 'required|numeric',
'detergent_pumps.*.active' => 'boolean',
'detergent_pumps.*.trigger' => 'required|string',
'detergent_pumps.*.xp' => 'required|numeric',
'detergent_pumps.*.xt' => 'required|numeric',
'detergent_pumps.*.total' => 'required|numeric',
'detergent_pumps.*.remaining' => 'required|numeric',
]);
dd('After validation, before update', $request->all());
// Update the device
$device->update([
'location_name' => $request->input('location_name'),
]);
dd('After update, before detergent pumps loop', $request->all());
// Update or create detergent pumps
foreach ($request->input('detergent_pumps') as $pumpData) {
if (isset($pumpData['id'])) {
// Update existing detergent pump
$detergentPump = DetergentPump::findOrFail($pumpData['id']);
$detergentPump->update($pumpData);
} else {
// Create new detergent pump
$device->detergentPumps()->create([
'name' => $pumpData['name'],
'dosage' => $pumpData['dosage'],
'active' => $pumpData['active'],
'trigger' => $pumpData['trigger'],
'xp' => $pumpData['xp'],
'xt' => $pumpData['xt'],
'total' => $pumpData['total'],
'remaining' => $pumpData['remaining'],
]);
}
}
dd('After detergent pumps loop', $request->all());
return redirect('/devices')->with('success', 'Device and detergent pumps updated successfully.');
}
public function destroy($id)
{
$device = Device::findOrFail($id);
$device->delete();
return redirect('/devices')->with('success', 'Device deleted successfully.');
}
}
edit.blade.php 文件是这个：

问题是代码在验证之前输入了 dd ，其中包含我在表单中输入的所有修改数据，这就是我将其注释掉的原因，但它没有到达第二个数据库。 验证有问题吗？
看起来，是的，如果您没有看到第二个
dd()要准确确定哪个输入有错误，您可以在
edit.blade.php@if(!empty($errors->messages()))
{{ dd($errors->messages()) }}
@endif
此外，要在
edit.blade.php@error("detergent_pumps." .$index. ".dosage")
<div class="text-danger">{{ $message }}</div>
@enderror
