Imagine a blog with posts and comments. An individual comment's URL might be posts/741/comments/1220.
However, I'd like to make the URL posts/741#1220, or even posts/741#comment-1230.
What's the least intrusive way of doing this, so that redirect_to comment_path(my_comment) points to the correct URL?

Rails routing is a two-way piece of machinery – rather as if you could turn trees into paper, and then turn paper back into trees. Specifically, it both connects incoming HTTP requests to the code in your application's controllers, and helps you generate URLs without having to hard-code them as strings.
Rails RESTful Design which creates seven routes all mapping to the user controller. Rails also allows you to define multiple resources in one line.
You could simply use
redirect_to post_path(comment.post, :anchor => "comment-#{comment.id}") 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 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
