在Laravel Eloquent中使用with()返回对象 [英] Return object using with() in Laravel Eloquent

问题描述

目前，我得到的数据如下:

Currently I get data like so:

->with(['posts' => function ($query) {
            $query->active()->available()->limit(1)->with('user');
            }])

，它以预期的对象数组形式返回用户数据.因为我正在使用一个限制，并且只需要一个结果，所以我想将其作为常规对象返回，所以不要:

and it returns the user data as an array of objects which is expected. Because I am using a limit and will only ever need one result, I'd like to return it as a regular object, so instead of:

"data": value,
"posts": [
    {
      "data": value,
      "user": {
        "data": value
      }
    }
  ]

我想将其返回为:

"data": value,
"post":
        {
          "data": value,
          "user": {
            "data": value
          }
        }

最好的方法是什么?

推荐答案

在模型上创建一个hasOne关联，以定义所需的范围.

Create a hasOne association on your model that defines the scope you'd like.

public function activePost()
{
    return $this->hasOne(Post::class)->active()->available();
]

然后调用with('activePost.user')，以为其关联用户加载该单个，活动和可用的帖子.

Then call with('activePost.user') to load that single, active and available post with it's associated user.
