How do I get the current absolute URL in Ruby on R

Question

How can I get the current absolute URL in my Ruby on Rails view?

The request.request_uri only returns the relative URL.

Answer 1

If you're using Rails 3.2 or Rails 4 you should use request.original_url to get the current URL.

---

Documentation for the method is at http://api.rubyonrails.org/classes/ActionDispatch/Request.html#method-i-original_url but if you're curious the implementation is:

def original_url
  base_url + original_fullpath
end

Answer 2

For rails 3 :

request.fullpath

Answer 3

None of the suggestions here in the thread helped me sadly, except the one where someone said he used the debugger to find what he looked for.

I've created some custom error pages instead of the standard 404 and 500, but request.url ended in /404 instead of the expected /non-existing-mumbo-jumbo.

What I needed to use was

request.original_url

Answer 4

For Ruby on Rails 3:

request.url
request.host_with_port

I fired up a debugger session and queried the request object:

request.public_methods

Answer 5

In Rails 3 you can use

request.original_url

Answer 6

Rails 4.0

you can use request.original_url, output will be as given below example

get "/articles?page=2"

request.original_url # => "http://www.example.com/articles?page=2"
