Laravel Eloquent hasManyThrough 关系 + 分页

Question

我有三个表：

Videos:
-id
-name
-another fields

Cats:
-id
-name
-another fields

Cats_videos:
-id
-cat_id
-video_id

和三个Eloquent模型：

class cat extends Model
{
    protected $table = 'cat';

    public function AllCatVideos()
    {
        return $this->hasManyThrough('App\videos', 'App\cats_videos','cat_id','id');
    }
}

class videos extends Model
{
    public $timestamps = false;
    protected $table ='videos';
}

class cats_videos extends Model
{
    protected $table = 'cats_videos';
}

所以，我想在一只猫中接收所有视频，然后对结果进行分页。我想这样做：

$cat = new Cats();
    $videos = $cat->find(58)->AllCatVideos()->toSql();

我收到这样的 sql：

select * from `videos` inner join `cats_videos` on `cats_videos`.`id` = `videos`.`id` where `cats_videos`.`cat_id` = 58

但我需要“cats_videos.video_id = videos.id”而不是“cats_videos.id = videos.id”。我如何使用 "hasManyThrough" 执行此操作？或者我应该看看别的东西？

Answer 1

问题已解决。我只需要使用 belongsToMany.

class cat extends Model{
public function Videos()
{
    return $this->belongsToMany('App\videos','cats_videos','cat_id','video_id');
}}
