Laravel-如何汇总子数据并将其传递给父@foreach

问题描述

我是laravel的新手。因此，在这种情况下，我试图对子数据求和并将其传递给父索引@foreach内的父名义列， 事情是idk，如何在控制器内部声明父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 ，它是父控制器

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'));
   }
}

在此控制器中，我声明了变量$ total，该变量将对SPJCreateDetail模型中的列“ nominal”求和，但idk如何在其中声明 其中 ，因为$ id是祖父母编号

如果我将 $ request-> id 放在 where

内，则在标称列内返回0

但是当我这样手动调用时会显示

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

my parent index after i put where id manually

但是我不希望那样，因为我希望动态调用我的ID并将其相加

我的 SPJCreate 模型是父模型

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 模型是子模型

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');
     }
}

对不起，我的英语不好，我希望你们能为我提供帮助，因为我坚持一个月试图找出答案:(，谢谢。

我的控制器内部有dd

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

它像这样返回 image

但是

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

它正确返回值 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>

                        <div class="dropdown-menu">

                        </div>
                      </div>
                      </td>
                    </tr>
                      @empty
                      <tr>
                        <td colspan="7" class="text-center">Tidak ada data <i class="far fa-frown fa-5"></i></td>
                      </tr>

解决方法

尝试一下。

   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">

                        <div class="dropdown-menu">

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