Question

我有以下数据库表结构

users
  id
  name

articles
  id
  about_id
  author_id
  text

以下用户：

1 Alex
2 John

And 2 articles one written by (author_id) John(2) about (about_id)
Alex(1) and other written by (author_id) Alex(1) about (about_id)
John(2).

我的问题是文章表的模型如何命名＆＃34;文章＆＃34;，应该如何看待下面提到的关系。我想访问文章对象来检索作者对象，如：

$article = Article::find(1);
$article->author;

并检索文章的用户对象：

$article = Article::find(1);
$article->about;

我必须提到我只有两个模型：文章和用户。

Answer 1

您的文章模型应如下所示

class Article extends Model {
    public function author() {
        return $this->belongsTo("App\User", 'author_id');
    }

    public function about() {
        return $this->belongsTo("App\User", 'about_id');
    }
}

Answer 2

您也可以使用hasMany

class Article extends Model {
    public function author() {
        return $this->hasMany("App\Author", 'author_id', 'id');
    }

    public function about() {
        return $this->hasMany("App\About", 'author_id', 'id');
    }
}

Answer 3

use App\User;
use App\Article;

class Article extends Model {

    public function author() {
        return $this->belongsTo(Article::class, 'author_id');
    }

    public function about() {
        return $this->belongsTo(User::class, 'about_id');
    }
}
