【问题描述】：
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
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，但我不知道如何在其中声明 where，因为 $id 是祖父母的身份证
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显示出来
$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。
我在我的控制器中 dd
$total = dd(SPJCreateDetail::where('id_spj', $request->id)->sum('nominal'));
它像这样返回 image
然而
$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>

@AndySong 我用我的 dd 编辑帖子，在那里你可以检查它:) 我错了 id 8 它是 id 6 因为 id 8 内没有数据
-
@AndySong 如果我只做了 dd($request->id) 它返回 null，代码是这样的吗？
$total = dd(SPJCreateDetail::where('id_spj', $request->id)->sum('nominal')); dd($request->id) -
@AndySong 我用网络路由更新了我的帖子
