问题描述
我在控制器中使用联接的数据捕获视图中有一个下拉列表,但当我尝试保存记录时,收到以下错误。
Method IlluminateSupportCollection::save does not exist.
我已尝试将雄辩语句更改为
$energy = DB::table('vehicleslog')->join('vehicle', 'vehicleslog.vehicle_id', '=', 'vehicle.id')->first();
而不是
$energy = DB::table('vehicleslog')->join('vehicle', 'vehicleslog.vehicle_id', '=', 'vehicle.id')->first();
但是,这会给我以下错误。
Call to undefined method stdClass::save()
有人知道正确的是什么吗?
控制器:
public function index()
{
// $energy = Maintenance::orderBy('id', 'desc')->paginate(5);
$energy = DB::table('vehicleslog')->join('vehicle', 'vehicleslog.vehicle_id', '=', 'vehicle.id')->get();
$cars = Vehicle::get();
$staff = Staff::all();
return view('admin.vmaintenance', compact('energy', 'cars', 'staff'));
}
public function store(Request $request)
{
// $energy = new Maintenance;
$energy = DB::table('vehicleslog')->join('vehicle', 'vehicleslog.vehicle_id', '=', 'vehicle.id')->first();
$cars = Vehicle::all();
$staff = Staff::get();
$energy->staff_key = $request->input('staff_key');
$energy->vehicle_id = $request->input('vehicle_id');
$energy->log_dt = $request->input('log_dt');
$energy->admin_time = $request->input('admin_time');
$energy->driving_time = $request->input('driving_time');
$energy->work_time = $request->input('work_time');
$energy->jobcard_count = $request->input('jobcard_count');
$energy->start_odo = $request->input('start_odo');
$energy->end_odo = $request->input('end_odo');
$energy->save();
return redirect('/vmaintenance')->with('success', 'data added');
}
查看:
<label>Select Vehicle</label>
<select name="vehicle_id" >
@foreach($cars as $car)
<option value="{{ $car->id }}">{{ $car['reg_number'] }}</option>
@endforeach
</select>
推荐答案
急切加载:
$energy=VehicleLog::with(‘Vehicle’)->;First();
也:
- 此变量从未在
store()
操作中使用:
$cars = Vehicle::all();
$staff = Staff::get();
- 您可以使用
fill()
方法:
$energy->fill($request->only([
'staff_key', 'vehicle_id', 'admin_time',
'driving_time', 'work_time', // ...
]));
