调用laravel关系时避免字符串

问题描述：

This is relationship in model

public function article_children() {
    return $this->hasMany(self::class, 'parent_id',self::PRIMARY_KEY);
}

I am calling it with this line

$article_type = ArticleType::with('article_children')->find($id);

My code works nice but what annoys me is that I have to pass method name 'article_children' as string and I am trying to avoid that ...

ideal solution would be

$article_type = ArticleType::with(ArticleType::someReferenceToMethodArticleChildren)->find($id);

So In far far away future I will have option to just CRTL + CLick on that reference and it would lead me directly to relation method in PHP-Storm.

If any one knows the answer how to improve that part of code let me know :)

I've got this working. On your ArticleType model, add:

public static $relChildren = "article_children";

Then when using ::with(), you can use:

ArticleType::with(ArticleType::$relChildren)->first();

I don't know if that would solve your issue of trying to find the reference via PHPStorm, but this seemed to work for string substituting.
