HasMany() 在 Laravel 中无法获取关系明智的记录

Question

目前，我正在使用 MySQL 数据库开发 laravel 6。所以我想获取具有许多关系的记录。获取多个 id 的训练强度记录——见图片TrainingGoalModel.php/** * training_intensity_details => get multiple intensity with current goal * * @return void */public function training_intensity_details(){    return $this->hasMany(TrainingIntensity::class, 'id', 'training_intensity_ids');}目标控制器$query = $query->with('training_intensity_details')->get();, 两者都适用,$query = $query->with(['training_intensity_details'])->get();但是，关系不适用。请帮我。

Answer 1

尝试..

   public function training_intensity_details()

    {

        return $this->hasMany(TrainingIntensity::class, 'training_intensity_ids', 'id');

    }
