在 Ruby on Rails 中为帖子添加标签 [英] Adding tags to posts in Ruby on Rails

问题描述

我正在使用 Scaffolding 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，就像在 StackOverflow 和 WordPress 上一样.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，但这不是一个好习惯，因为我希望读者按标签浏览(例如 /tags/web20 或 /tags/lol ).我该怎么做?

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 "acts as taggable on" 通常是实现标签的首选方式.

Tagging is so common that implementations are a commodity. I believe "acts as taggable on" is usually the preferred way of implementing tags.

如果你想自己实现它，你可以深入源代码寻找一些想法.
