Question

我有四个表：characters，pets，characters_pets和characters_pets_metadata。一个角色在数据透视表characters_pets上有很多宠物，但我还需要从元数据表中获取数据：

class Character extends Model {

    protected $table = 'characters';

    public function pets() {
        return $this->belongsToMany('Pet', 'characters_pets');
    }
}



class CharacterPet extends Model {

    protected $table = 'characters_pets';

    public function metadata() {
        return $this->hasMany('PetMetadata');
    }

}

如何通过关系获取每个角色宠物的元数据？

Answer 1

我相信你在找类似的东西：

$character = Character::find(1);

foreach($character->pets as $pet){

    // you can access any pet information here

    foreach($pet->metadata as $meta){

       var_dump($meta); // your meta information here

    }

}
