Laravel eloquent 插入关系数据

Question

我有两个模型：trainers 和 trainerClubs。我有 json 数组。每个 json 数组都有另一个 array.When 一个 json 来找我，我想将它们同时添加到关系模型中。例如; Trainer::insert($request->all());

我的json例子；

[
    {
        "identity_no": "111222333",
        "first_name": "john",
        "last_name": "doe",
        "TrainerClubs": [
            {
                "club_id": 1,
                "work_type": 1
            },
            {
                "club_id": 2,
                "work_type": 1
            }
        ]
    },
    {
        "identity_no": "444555666",
        "first_name": "jane",
        "last_name": "doe",
        "TrainerClubs": [
            {
                "club_id": 1,
                "work_type": 3
            },
            {
                "club_id": 13,
                "work_type": 3
            }
        ]
    }
]

和我的模特；

class Trainer extends Model
{
    public $timestamps = true;

    protected $guarded = ['id'];

    public function TrainerClubs()
    {
        return $this->hasMany('App\Modules\Trainer\Models\TrainerClub', 'trainer_id');
    }
}

class TrainerClub extends Model
{
    protected $guarded = ['id','created_at','updated_at'];

    public function Trainer()
    {
        return $this->belongsTo('App\Modules\Trainer\Models\Trainer');
    }
}

我当前的工作代码；

    public function create(array $data)
    {
        foreach ($data as $trainer) {
            $crrTrainer = (array)$trainer;
            $clubs = array_pop($crrTrainer);
            $addedTrainer = Trainer::create($crrTrainer);
            foreach ($clubs as $trainerClub) {
                $addedTrainer->TrainerClubs()->create($trainerClub);
            }
        }
        return true;
    }

感谢帮助

Answer 1

简而言之，您不能同时保存两个模型。在您的情况下，您必须首先创建培训师：

 $addedTrainer = Trainer::create($crrTrainer);

稍后插入球杆。您可以做的不同是同时创建所有俱乐部，而不必使用 createMany:

循环遍历它们

$addedTrainer->TrainerClubs()->createMany($clubs);
