关系表上的雄辩查询

Question

你好我有两个模特地址和 Kontokorrent 他们有一对一的关系。我想创建一个搜索功能并在地址和 Kontokorrent 列

之后搜索

我的模特：

地址模型

class Adress extends Model
{
    protected $table = "Adressen";
    protected $primaryKey = 'Adresse';
    public $timestamps = false;

    public function scopeSearchAdress($query, $searchTerm)
    {
        return $query->where('LieferOrt', 'LIKE', '%'.$searchTerm.'%')
                     ->orWhere('Name1', 'LIKE', '%'.$searchTerm.'%')
                     ->orWhere('LieferStrasse', 'LIKE', '%'.$searchTerm.'%');              
    }

    public function kontokorrent()
    {
        return $this->hasOne(Kontokorrent::class, 'Adresse');
    }
}

Kontokorrent模型

class Kontokorrent extends Model
{
    protected $table = "Kontokorrent";
    protected $primaryKey = 'Adresse';
    public $timestamps = false;

    public function scopeSearchKto($query, $searchTerm)
    {
        return $query->where('Kto', 'LIKE', '%'.$searchTerm.'%');              
    }

    public function adress()
    { 
        return $this->belongsTo(Adress::class, 'Adresse');
    }
}

控制器

class AdressesController extends Controller
{
    public function index(Request $request)
    {
        $searchTerm = $request->input('searchTerm');

        $adresses = Adress::whereHas('kontokorrent', function($query) use($searchTerm) {
            $query->where('KtoArt', 'D')
                  ->searchKto('K75688'); // this is working
                  // -> searchKto($searchTerm); this is NOT working       
        })->orderBy('Name1')
        ->searchAdress($searchTerm)
        ->paginate(60);

        return view('adresse.index', compact('adresses', 'searchTerm'));
    }
}

地址模型中的搜索功能正常运行。现在我想在 Kontokorrent 中搜索客户ID（Kto）。所以我在 Kontokorrent 中创建了一个范围，并将其链接到控制器搜索功能。

->searchKto('K75688') ....这是有效的我得到一个结果
->searchKto($searchTerm) ....当我在输入字段中输入客户ID并点击回车时，这不起作用。我得到一个0行表。

                            <td>{{ $adress->LieferPLZ }}</td>
                            <td>{{ $adress->LieferLand }}</td>
                        </tr>
                    @endforeach
                @else
                    <tr><td colspan="6" class="text-center">Kein Eintrag gefunden.</td></tr>
                @endif
            </tbody>
        </table>
    </div>
</div>
{{ $adresses->appends(['searchTerm' => $searchTerm])->links() }}
@endsection

我不明白为什么我会得到一张空桌子。
