如何解决Laravel-如何汇总子数据并将其传递给父@foreach
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
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::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>

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">
<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>
