Laravel

Question

我是 laravel 的新手。所以在这种情况下，我试图对 child 数据求和并将其传递给 parent 索引 @foreach 内的 parent 标称列，问题是我不知道如何在控制器

中声明parent id

here's my parent index which i want to show the sum child each parent id in @foreach

here's my child index that i've already sum it, i want to show it into parent @foreach nominal column as well

这是我的 SPJCreateController，它是 parent 控制器

class SPJCreateController extends Controller
{
   public function index(Request $request, $id)
   {
      $kegiatan = DPAKegiatan::with('dpatahun')->findorfail($id);
      $data = SPJCreate::with('spjcreatedetail')
              ->where('id_dpakegiatan', $kegiatan->id)
              ->orderBy('created_at', 'asc')
              ->paginate(10);
      $total = SPJCreateDetail::where('id_spj', $request->id)->sum('nominal');
      return view('spj.kegiatan.create.data', compact('kegiatan','data','total'));
   }
}

在这个控制器中，我声明了变量 $total，它将在 SPJCreateDetail 模型中对列 'nominal' 求和，但不知道如何声明 where 在里面，因为 $id 是 grandparent

的 ID

如果我把 $request->id 放在 where

但是当我像这样手动调用它时它显示了

$total = SPJCreateDetail::where('id_spj', 6)->sum('nominal');

my parent index after i put where id manually

但我不希望这样，因为我希望动态调用我的 ID 并对它的每一行求和

我的 SPJCreate 模型是 parent 模型

class SPJCreate extends Model
{
    protected $primaryKey = 'id';
    protected $table = 'spj';
    protected $fillable = ['id_dpakegiatan','tipebelanja','tipebelanjadetail'];

    public function dpakegiatan()
    {
          return $this->belongsTo(DPAKegiatan::class, 'id_dpakegiatan');
    }

    public function spjcreatedetail()
    {
          return $this->hasMany(DPAKegiatan::class, 'id');
    }
}

我的 SPJCreateDetail 模型是 child 模型

class SPJCreateDetail extends Model
{
     protected $primaryKey = 'id';
     protected $table = 'spj_detail';
     protected $fillable = ['id_spj','id_listbelanja','ket','penerima','nominal','ppn','pph21','pph22','pph23'];

     public function spjcreate()
     {
          return $this->belongsTo(SPJCreate::class, 'id_spj');
     }
}

抱歉我的英语不好，我希望你们能帮助我，因为我坚持了一个月试图弄明白:(，谢谢。

我在我的控制器中添加

$total = dd(SPJCreateDetail::where('id_spj', $request->id)->sum('nominal'));

它return是这样的 image

然而

$total = dd(SPJCreateDetail::where('id_spj', 6)->sum('nominal'));

它 return 值正确 image

这是我的网络路线

    // --Here's my grandparent routes-- //
Route::get('/spj/kegiatan&id={spjkeg}', 'SPJKegController@index')->name('spjkeg')->middleware('auth');
    // ------------- //
        
    // --Here's my Parent Route Which is Gonna show my child sum-- //
Route::get('/spj/kegiatan/create&id={spjcreate}', 'SPJCreateController@index')->name('spj')->middleware('auth');
Route::post('/spj/kegiatan/create/store&id={spjcreate}', 'SPJCreateController@store')->name('spj.store')->middleware('auth');
Route::post('/spj/kegiatan/create/updt&id={spjcreate}', 'SPJCreateController@update')->name('spj.update')->middleware('auth');
Route::delete('/spj/kegiatan/create/del&id={spjcreate}', 'SPJCreateController@destroy')->name('spj.destroy')->middleware('auth');
    // ------------ //
                
    // --Here's the child route-- //
Route::get('/spj/kegiatan/create/detail&id={spjdet}', 'SPJCreateDetailController@index')->name('spj.detail')->middleware('auth');
Route::post('/spj/kegiatan/create/detail/store&id={spjdet}', 'SPJCreateDetailController@store')->name('spj.detail.store')->middleware('auth');
Route::post('/spj/kegiatan/create/detail/updt&id={spjdet}', 'SPJCreateDetailController@update')->name('spj.detail.update')->middleware('auth');
Route::delete('/spj/kegiatan/create/detail/del&id={spjdet}', 'SPJCreateDetailController@destroy')->name('spj.detail.destroy')->middleware('auth');
    // ------------ //

这是我的 View.blade.php

@php $no = 0; @endphp
@forelse($data as $spj => $result)
@php $no++; @endphp
                    <tr>
                      <td class="text-center">{{ $spj + $data->firstitem() }}.</td>
                      <td class="text-center"><b>{{ $result->tipebelanjadetail }}</b></td>
                      <td class="text-center">{{ $total }}</td>
                      <td class="text-center">
                      <div class="dropdown">
                        <button data-id="{{ $result->id }}" data-idtipebelanja="{{ $result->tipebelanja }}" data-idtipebelanjadetail="{{ $result->tipebelanjadetail }}" data-toggle="modal" data-target="#editspj" class="btn btn-success btn-s" style="background-color:#138496;border-color:#138496"><i class="fad fa-pencil"></i></button>

试试这个。

   public function index($spjcreate)
   {
      $kegiatan = DPAKegiatan::with('dpatahun')->findorfail($spjcreate);
      $data = SPJCreate::with('spjcreatedetail')
              ->where('id_dpakegiatan', $kegiatan->id)
              ->withCount(['spjcreatedetail AS total' => function ($query) {
                  $query->select(DB::raw('SUM(nominal) as total'));
              }])
              ->orderBy('created_at', 'asc')
              ->paginate(10);

      return view('spj.kegiatan.create.data', compact('kegiatan','data'));
   }

@php $no = 0; @endphp
@forelse($data as $spj => $result)
@php $no++; @endphp
                    <tr>
                      <td class="text-center">{{ $spj + $data->firstitem() }}.</td>
                      <td class="text-center"><b>{{ $result->tipebelanjadetail }}</b></td>
                      <td class="text-center">{{ $result->total }}</td>
                      <td class="text-center">
                      <div class="dropdown">
                        <button data-id="{{ $result->id }}" data-idtipebelanja="{{ $result->tipebelanja }}" data-idtipebelanjadetail="{{ $result->tipebelanjadetail }}" data-toggle="modal" data-target="#editspj" class="btn btn-success btn-s" style="background-color:#138496;border-color:#138496"><i class="fad fa-pencil"></i></button>

                        <div class="dropdown-menu">

                        </div>
                      </div>
                      </td>
                    </tr>
                      @empty
                      <tr>
