我是 laravel 的新手。所以在这种情况下，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，问题是 idk 如何在控制器中声明父 ID
这是我的父索引，我想在@foreach 中显示每个父 ID 的总和子
这是我已经对它求和的子索引，我也想将它显示到父 @foreach 名义列中
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'));
}
}
在这个控制器中，我声明了变量 $total ，它将对 SPJCreateDetail 模型中的“名义”列求和，但是我知道如何声明其中的位置，因为 $id 是祖父母的 id
如果我将$request->id放在where内，它会在名义列内返回 0
但是当我像这样手动调用它时它会显示
$total = SPJCreateDetail::where('id_spj', 6)->sum('nominal');
但我不希望这样，因为我希望动态调用我的 id 并对每一行求和
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，我希望你们能帮助我，因为我坚持了一个月试图弄清楚:(，谢谢。
我 dd 在我的控制器内
$total = dd(SPJCreateDetail::where('id_spj', $request->id)->sum('nominal'));
它像这张 图片一样返回
然而
$total = dd(SPJCreateDetail::where('id_spj', 6)->sum('nominal'));
它正确返回值 图像
这是我的网络路线
