问题描述
我正在使用脚手架在Rails中创建一个博客.我想在每个帖子上添加一个标签"字段，例如StackOverflow和WordPress.我可以使用字符串类型(rails generate scaffold post title:string body:text tags:string)然后用逗号分隔来执行此操作，但这不是一个好习惯，因为我希望读者按标记(例如/tags/web20或/tags/lol)浏览.我该怎么办?
I am creating a blog in Rails using Scaffolding. I want to add a 'tags' field on each post like on StackOverflow and WordPress. I can do this with the string type ( rails generate scaffold post title:string body:text tags:string ) and then comma separated, but it's not good practice since I want the reader to browse by tags ( e.g. /tags/web20 or /tags/lol ). How can I do this?
推荐答案
标记是如此普遍，以至于实现是一种商品.我相信作为可标记对象" 通常是实现标记的首选方法
Tagging is so common that implementations are a commodity. I believe "acts as taggable on" is usually the preferred way of implementing tags.
