使用 eloquent 向刀片显示 laravel 数据时出错

Question

我有这个承包商 Model

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

和承包商详情 Model

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

我可以检索 Contractors Model 下的所有列，但是每当我这样做$contractors->ContractorDetails->id时，它都会显示此错误“尝试获取非对象的属性 'id'” 。 但是，当我只使用这个$contractors->ContractorDetails时，它能够显示这个集合{"id":6,"contractors_id":24}

我的 controller 看起来像这样

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

我的刀片文件

        <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">

                       {{ $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">

'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>

任何帮助将不胜感激

Answer 1

尝试先检查如下：

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

您可能会遇到没有contractorDetails 的情况。

Answer 2

找到了解决办法。

我在我的承包商 Model 下创建了另一个 function

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

现在我可以用这个从 ContractorDetails Model 获取 ID

$contractors->ContractorDetails
