Php 如何根据从另一外键显示的外键显示表格/Laravel 6

型号：

follow\u-up.id\u-priority

是

priority.id

控制器：

public function followup() 
{
   return $this->hasMany('App\FollowUp', 'id_log', 'id')
   ->select(['id', 'id_log', 'request', 'id_priority']);
}

返回的json数据片段：

$test = DmLog::withTrashed()
    ->with('followup')
    ->with('department')
    ->with('membership')
    ->with('room')
    ->with('roommove')
    ->with('communication')
    ->with('category')
    ->with('userCreator')
    ->with('userUpdator')
    ->find($id);

您能告诉我如何根据外键显示表格优先级吗？外键是

id\u priority

？

好的。。。这是一个误会，所以我想得到的结果是：

[{...},
    "created_at": "2020-12-29T18:14:26.000000Z",
    "updated_at": null,
    "deleted_at": null,
    "followup": [
        {
            "id": 2,
            "id_log": 1,
            "request": "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.",
            "id_priority": 2
        },
        {
            "id": 3,
            "id_log": 1,
            "request": "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.",
            "id_priority": 1
        }
    ],
    "department": {
        "id": 2,
        "department": "Kitchen"
    },
{...}]

---

您可以使用方法调用

上的闭包函数：

[{...},
    "created_at": "2020-12-29T18:14:26.000000Z",
    "updated_at": null,
    "deleted_at": null,
    "followup": [
        {
            "id": 2,
            "id_log": 1,
            "request": "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.",
            "id_priority": 2
            "priority": {
               "id": 2
               "priority": "not urgent"
            }
        },
        {
            "id": 3,
            "id_log": 1,
            "request": "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.",
            "id_priority": 1,
            "priority": {
               "id": 1
               "priority": "urgent"
            }
        }
    ],
    "department": {
        "id": 2,
        "department": "Kitchen"
    },
{...}]

如果你在followup模型中定义了优先级关系，你可以通过调用->with（'followup.priority'）轻松加载它，也可以通过传递数组->with['followup'，'followup.priority'，…]将所有关系组合在一起，这是一个误解，我用我想要得到的结果编辑了我的帖子，因此更容易理解，感谢您的回答：）如果尚未定义，您可以在Followup模型上定义
priority
关系，然后使用（'Followup.priority'）立即加载
我没有这样做，但您的评论很有帮助，谢谢！有一个误会，我编辑了我的帖子，结果是我想要得到的，所以更容易理解，谢谢你的回答：）@Bernard我更新了我的答案。我没有这样做，但你的答案很有帮助，谢谢@伯纳德，不客气
use Illuminate\Database\Eloquent\Relations\BelongsTo;

$test = DmLog::withTrashed()
    ->with([
        'followup' => function (BelongsTo $relationship) {
            $relationship->select(['id', 'priority']);
         },
    ]);
