Php 通用模型方法的正确用法

我是拉雷维尔的新手，正在努力了解基本用法

目前，我的控制器中有以下与术语/分类模型相关的代码

$taxonomy = Taxonomy::where('slug', '=', str_slug('brand'))->first();

if ( isset($taxonomy->id) ) {

  $term = $taxonomy->term()->firstOrCreate(array('slug' => str_slug($request->name)));

  $term->name = $request->name;

  $term->save();
}

我想让其他控制器使用它，但不确定正确的位置

我曾考虑将它放在“addTerm”方法下的分类模型中，但Taxonomy:：where（）感觉不太合适

---

正确的方法是什么？它应该放在分类模型中还是放在方法的帮助文件中？

在我看来，这不是唯一的方法。我喜欢使用repository模式，并将与sql相关的方法存储在那里，以便在整个应用程序中重用它们

---

例如，这里对它进行了解释，我发现这篇文章非常有用/有趣：

当我自己解决这个问题时，我使用了helper类。我想让我的模型专注于数据结构，并在多个控制器之间共享某些活动

下面的代码是处理邮件地址的示例。用例是其他几个实体将与一个或多个地址关联。所有权通过多对多关系的中间表进行管理

（*这是我第一次接触到存储库模式，它看起来非常吸引人。我将进一步探讨它。）

app/Helpers/Models/Address.php

我见过存储库名称好几次，所以我会看看这些名称，看看我是否能自己使用它。非常感谢！将提供最新信息。
