# معرّف فريد لعناصر DOM في Rails

> يوفّر Rails كثيرًا من الـ view helpers الرائعة، ومنها dom_id:

Published: 2020-10-14 · Topic: [ruby on rails](https://oozou.com/ar/til-topics/ruby-on-rails) ([markdown](https://oozou.com/ar/til-topics/ruby-on-rails.md))

يوفّر Rails كثيرًا من الـ view helpers الرائعة، ومنها *dom\_id:*

```
dom_id(Post.find(12))       <em># => "post_23"</em>
dom_id(Post.new)            <em># => "new_post"
language-rails</em>
```

ويمكنكم أيضًا تحديد بادئة:

```
dom_id(Post.find(23), :edit) <em># => "edit_post_23"</em>
dom_id(Post.new, :custom)    <em># => "custom_post"
language-rails</em>
```
