在Rails 3中如何在ID中使用锚作为ID？ [英] How do you use anchors for IDs in routes in Rails 3?

问题描述

想象一个博客，其中有个帖子和个评论。单个评论的URL可能是 posts / 741 / comments / 1220 。

Imagine a blog with posts and comments. An individual comment's URL might be posts/741/comments/1220.

不过，我想URL posts / 741＃1220 ，甚至 posts / 741＃comment-1230 。

However, I'd like to make the URL posts/741#1220, or even posts/741#comment-1230.

这样做的最不麻烦方式是什么，以便 redirect_to comment_path（my_comment）指向正确的URL？

What's the least intrusive way of doing this, so that redirect_to comment_path(my_comment) points to the correct URL?

推荐答案

您可以简单地使用

redirect_to post_path(comment.post, :anchor => "comment-#{comment.id}")

到使用锚点手动构建URL。这样，您仍然可以在路线中将您的评论的绝对URL设为 posts /：post_id / comments /：comment_id 。您还可以在例如application_controller.rb

to manually build the URL with the anchor. That way, you can still have the absolute URL to your comments as posts/:post_id/comments/:comment_id in your routes. You can also create a helper method in e.g. application_controller.rb

class ApplicationController
  helper :comment_link

  def comment_link(comment)
    post_path(comment.post, :anchor => "comment-#{comment.id}")
  end
end
