使用 eloquent 向 blade 显示 laravel 数据时出错

Question

我有这个承包商模型

public function ContractorDetails()
{
    return $this->hasOne(ContractorDetails::class)->select('id', 'contractors_id');
}

和 ContractorDetails 模型

  public function Contractors()
    {
        return $this->belongsTo(Contractors::class);
    }

我可以检索 Contractors 模型下的所有列，但每当我这样做时 $contractors->ContractorDetails->id，它都会显示此错误 "试图获得属性 'id' 的 non-object" 。然而，当我只使用这个 $contractors->ContractorDetails 时，它能够显示这个 collection {"id":6,"contractors_id":24}

我的控制器是这样的

**$contractors = Contractors::orderby('name')->with('ContractorDetails')->get();**

我的blade文件

        <tbody> 
            @foreach($contractors as $contractor)
            <tr class="bg-white lg:hover:bg-gray-100 flex lg:table-row flex-row lg:flex-row flex-wrap lg:flex-no-wrap mb-10 lg:mb-0">
                <td class="w-full lg:w-auto p-3 text-gray-800 text-center border border-b block lg:table-cell relative lg:static">
                    <span class="lg:hidden absolute top-auto left-0 bg-blue-200 px-1 py-1 text-xs font-bold"> Contractor Name</span>
                       {{ $contractor->name }}
                </td>
                <td class="w-full lg:w-auto p-3 text-gray-800 text-center border border-b text-center block lg:table-cell relative lg:static">
                    <span class="lg:hidden absolute top-auto left-0  bg-blue-200 px-1 py-1 text-xs font-bold">Status</span>
                    <span class="{{$contractor->status == 0 ? 'px-2 inline-flex text-xs leading-5 font-semibold rounded-full bg-yellow-100 text-green-800' : 'px-2 inline-flex text-xs leading-5 font-semibold rounded-full bg-green-100 text-green-800' }}"> {{$contractor->status == 0 ? 'onHold' : 'Approved' }}</span>
                </td>

                <td class="w-full lg:w-auto p-3 text-gray-800 text-center border border-b text-center block lg:table-cell relative lg:static">
                    <span class="lg:hidden absolute top-auto left-0  bg-blue-200 px-1 py-1 text-xs font-bold">Actions</span>
                    <x-jet-button wire:click="{{ route('ContractorID', [$contractor->ContractorDetails->id])}}" wire:loading.attr="disabled">
                        {{ __('EDIT') }}
                        </x-jet-danger-button>
                        <x-jet-danger-button wire:click="confirmContractorDeletion( {{$contractor->id }})" wire:loading.attr="disabled">
                            {{ __('Delete') }}
                        </x-jet-danger-button>

                </td>
            </tr>
            @endforeach
        </tbody>

如有任何帮助，我们将不胜感激

Answer 1

先尝试检查如下：

isset($contractors->ContractorDetails->id) ? $contractors->ContractorDetails->id : 'No result found'

您可能遇到还没有 contractorDetails 的情况。

Answer 2

已找到修复程序。

我在我的承包商模型下创建了另一个函数

public function getContractorDetailsAttribute()
{
    return $this->ContractorDetails()->pluck('id')->first();
}

现在我可以用这个

从 ContractorDetails 模型中获取 ID

$contractors->ContractorDetails
