假设我想在图书模型中获取作者的名字
// app/Book.php
protected $appends = ['author_name'];
public function author() {
return belongsTo(Author::class, 'author_id');
}
public function getAuthorNameAttribute() {
return $this->author->name;
}
但是这也会将整个作者集添加到最终的书籍集中,这会在尝试加载100本书时增加加载时间,现在我通过这样的名字删除作者来解决这个问题] >
// app/Book.php protected $appends = ['author_name']; public function author() { return belongsTo(Author::class, 'author_id'); } public function getAuthorNameAttribute() { $authorName = $this->author->name; unset($this->author); return $authorName; }
有更好的方法吗?还是我错过了雄辩的功能?
