如何将枢轴关系附加或附加到模型? [英] How to append or attach a pivot relationship to a model?

问题描述

每当我从律师档案表格中获取律师记录时，我都会尝试从side_areas表中获取律师的执业区域记录.这两个表(practice_areas和律师个人资料)与名为(lawyer_practice_area)的数据透视表相关

I am trying to get the practice area record of lawyers from practice_areas table along side each time I get a lawyer's record from lawyer_profiles_table. This two tables (practice_areas and lawyer_profiles) are related with a pivot table named (lawyer_practice_area)

下面的代码来自LawyerProfile模型

This code below are from the LawyerProfile Model

public function practice_areas()
    {
        return $this->belongsToMany(PracticeArea::class, "lawyer_practice_area", "practice_area_id", "lawyer_id");
    }

我尝试通过以下操作通过属性获取它

I tried getting it through an attribute by doing the below

public function getPracticeAreasAttribute()
{
    return $this->practice_areas();
}

然后以这种方式附加

protected $appends = ["practice_areas"];

但是我一直在邮递员那里得到这个结果-"withtimestamps":"false"

but I keep getting this result on postman - "withtimestamps":"false"

请参见下面的输出:-

 "id": 1,
        "city": "Hintztown",
        "state": "Iowa",
        "longitude": "-163.884102",
        "latitude": "-18.127927",
        "lawyer_profile": {
            "id": 26,
            "email": "[e-mail]",
            "name": "Raoul Hegmann",
            "primary_location_id": 1,
            "photo_id": 39,
            "phone_number": "887.299.6204 x456",
            "about_lawyer": "Distinctio eos omnis autem error.",
            "practice_areas": {
                "withTimestamps": false
            }
        }
    },

推荐答案

可能要使用的是看看文档.

$books = App\Book::with('author')->get();

foreach ($books as $book) {
    echo $book->author->name;
}
