Property [kodeSparepart] does not exist on this collection instance - laravel

Question

I want to get all of the data from sparepart database using all() function, then use foreach in view to access the data, but I keep get that error. It works fine when I use the same method for other view blade.
Controller
public function LaporanSisaStok(Request $request) {
if($request->kode == "")
{
$spareparts = Sparepart::all();
return view('laporan/sisaStok')->with(['spareparts' => $spareparts]);
}
else {
$query = DB::table("historisparepart")->select(DB::raw('EXTRACT(MONTH FROM tanggal) AS Bulan, SUM(jumlah) as Sisa'))
->where('kodeSparepart', $request->kode)
->groupBy(DB::raw('EXTRACT(MONTH FROM tanggal)'))
->get();
return view('printPreview/sisaStok', ['data'=>$query]);
}
}
View
<form method="POST" action="{{ route('laporan.sisaStok') }}" enctype="multipart/form-data">
#csrf
<div class="form-group-row">
<label for="sparepart" class="col-sm-2 col-form-label">Sparepart</label>
<select class="custom-select" id="kode" name="kode">
<option value="">-Pilih Sparepart-</option>
foreach($spareparts as $sparepart)
{
<option value="{{$sparepart->kodeSparepart}}"> {{$sparepart->namaSparepart}} </option>
}
</select>
</div>

<button type="submit" class="btn btn-info"><i class="oi oi-task"></i> Cari </button>

Answer 1

You aren't looping through anything. You need to give the foreach() method a variable from your spareparts collection. I think it might help you avoid confusion, to name the collection variables plural:
In your controller:
$spareparts = Sparepart::all();
return view('laporan/sisaStok', compact('spareparts'));
Then, most importantly, you need to tell foreach what it should produce. In your view, change:
foreach($sparepart)
to
#foreach($spareparts as $sparepart)
Don't forget you are in blade, so use the # before the foreach. Then, assuming you actually have a property on the spareparts model called kodeSparepart, this should work fine.

Answer 2

This is not a looping syntax in the laravel view
foreach($spareparts as $sparepart)
{
<option value="{{$sparepart->kodeSparepart}}"> {{$sparepart->namaSparepart}} </option>
}
It should be like this
#foreach($spareparts as $sparepart)
<option value="{{$sparepart->kodeSparepart}}"> {{$sparepart->namaSparepart}} </option>
#endforeach
And another problem is you are passing the data in wrong way. It should be like this
return view('printPreview/sisaStok', ['spareparts'=>$query]);

Answer 3

You shoud use the plural of your dtb name to loop over the values so your 'sparepart' variable should change to 'spareparts'
$sparepart = Sparepart::all();
return view('laporan/sisaStok')->with(['spareparts' => $sparepart]);
In your view change your loop to the new variable and loop using your current variable, so your view shoul look like this:
View
<div class="form-group-row">
<label for="sparepart" class="col-sm-2 col-form-label">Sparepart</label>
<select class="custom-select" id="kode" name="kode">
<option value="">-Pilih Sparepart-</option>
#foreach($spareparts as $sparepart)
{
<option value="{{$sparepart->kodeSparepart}}"> {{$sparepart->namaSparepart}} </option>
}
#endforeach
</select>
</div>
