如何在Laravel中插入一对多关系

// Article.php
namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Article extends Model
{
    public function comments()
    {
        return $this->hasMany(Comment::class);
    }
}

// Comment.php
namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Comment extends Model
{
    public function article()
    {
        return $this->belongsTo(Article::class);
    }
}

// 在控制器中插入数据
use App\Models\Article;
use App\Models\Comment;

$article = new Article;
$article->title = 'Laravel One-to-Many Relationship';
$article->content = 'This is an article about Laravel one-to-many relationship.';
$article->save();

$comment = new Comment;
$comment->content = 'Great article!';
$article->comments()->save($comment);
