如何在rails中为options_from_collection_for_select添加数据属性 [英] How to add data attribute for options_from_collection_for_select in rails

问题描述

将此视为我的选择标记

<%= select_tag "post[brand_slug]", options_from_collection_for_select(@products, 'slug', 'name'), prompt: 'select' %>

这很好用，但我需要一个数据属性

This works fine but I need a data attribute

<%= select_tag "post[brand_slug]", options_from_collection_for_select(@products, 'slug', 'name'), data: {id: @products.id} , prompt: 'select' %>

@product.id 不起作用.我怎样才能获得ID

@product.id is not working. How can I get the ID too

推荐答案

尝试以下操作:

<%= select_tag "post[brand_slug]", options_for_select(@products.map{ |product| [product.name, product.slug, { 'data-id' => product.id }] }), prompt: 'select' %>
