我有一个LocationDivision模型存在division_id并且division_name存在。我想通过将数据存储在表中来获取该division_id数据users。

用户模型

public function division()
{
    return $this->belongsTo(LocationDivision::class, 'division_id');
}

控制器

public function editProfile()
{
    $users = User::with('division')->get();
    $divisions = LocationDivision::select('division_id', 'division_name')->orderBy('division_name')->get();
    $districts = LocationDistrict::select('id', 'district_name')->orderBy('division_id')->get();
    $sub_districts = LocationSubDistrict::select('id', 'sub_district_name')->orderBy('district_id')->get();
    $branches = LocationBranch::select('id', 'branch_name')->orderBy('sub_district_id')->get();
    $zips = LocationZip::select('id', 'zip_code')->orderBy('zip_code')->get();
    
    return view('durrbar.accounts.home.settings', compact('users', 'divisions', 'districts', 'sub_districts', 'branches', 'zips'));
}

刀片/视图

@foreach ($users as $user)
    <option value="{{ $user->division->division_id }}">
        {{ $user->division->division_name }}
    </option>
@endforeach

毕竟，我遇到了错误：

尝试在 null 上读取属性“division_id”

更新
通过使用->has('division')，因为$users = User::with('division')->has('division')->get()它工作正常。但是当我想使用多个 eloquent$users = User::with('division', 'district', 'subdistrict', 'branch', 'zip')->has('division', 'district', 'subdistrict', 'branch', 'zip')->get();时，它会给出同样的错误。
