How do I get the current absolute URL in Ruby on Rails?

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

For Rails 3.2 or Rails 4+

You should use request.original_url to get the current URL. Source code on current repo found here.

This method is documented at original_url method, but if you're curious, the implementation is:

def original_url
  base_url + original_fullpath
end

---

For Rails 3:

You can write "#{request.protocol}#{request.host_with_port}#{request.fullpath}", since request.url is now deprecated.

---

For Rails 2:

You can write request.url instead of request.request_uri. This combines the protocol (usually http://) with the host, and request_uri to give you the full address.

Answer 2

I think that the Ruby on Rails 3.0 method is now request.fullpath.

Answer 3

You could use url_for(only_path: false)

Answer 4

DEPRECATION WARNING: Using #request_uri is deprecated. Use fullpath instead.

Answer 5

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 6

You can add this current_url method in the ApplicationController to return the current URL and allow merging in other parameters

# https://x.com/y/1?page=1 
# + current_url( :page => 3 )
# = https://x.com/y/1?page=3
def current_url(overwrite={})
    url_for :only_path => false, :params => params.merge(overwrite)
end

Example Usage:

current_url --> http://...
current_url(:page=>4) --> http://...&page=4

Answer 7

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 8

In Ruby on Rails 3.1.0.rc4:

 request.fullpath

Answer 9

I needed the application URL but with the subdirectory. I used:

root_url(:only_path => false)

Answer 10

 url_for(params)

And you can easily add some new parameter:

url_for(params.merge(:tag => "lol"))

Answer 11

I think request.domain would work, but what if you're in a sub directory like blah.blah.com? Something like this could work:

<%= request.env["HTTP_HOST"] + page = "/" + request.path_parameters['controller'] + "/" + request.path_parameters['action'] %>

Change the parameters based on your path structure.

Hope that helps!

Answer 12

It looks like request_uri is deprecated in Ruby on Rails 3.

Using #request_uri is deprecated. Use fullpath instead.

Answer 13

Using Ruby 1.9.3-p194 and Ruby on Rails 3.2.6:

If request.fullpath doesn't work for you, try request.env["HTTP_REFERER"]

Here's my story below.

I got similar problem with detecting current URL (which is shown in address bar for user in her browser) for cumulative pages which combines information from different controllers, for example, http://localhost:3002/users/1/history/issues.

The user can switch to different lists of types of issues. All those lists are loaded via Ajax from different controllers/partials (without reloading).

The problem was to set the correct path for the back button in each item of the list so the back button could work correctly both in its own page and in the cumulative page history.

In case I use request.fullpath, it returns the path of last JavaScript request which is definitely not the URL I'm looking for.

So I used request.env["HTTP_REFERER"] which stores the URL of the last reloaded request.

Here's an excerpt from the partial to make a decision

- if request.env["HTTP_REFERER"].to_s.scan("history").length > 0
  - back_url = user_history_issue_path(@user, list: "needed_type")
- else
  - back_url = user_needed_type_issue_path(@user)
- remote ||= false
=link_to t("static.back"), back_url, :remote => remote

Answer 14

This works for Ruby on Rails 3.0 and should be supported by most versions of Ruby on Rails:

request.env['REQUEST_URI']

Answer 15

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 16

If by relative, you mean just without the domain, then look into request.domain.

Answer 17

You can use the ruby method:

:root_url

which will get the full path with base url:

localhost:3000/bla

Answer 18

(url_for(:only_path => false) == "/" )? root_url : url_for(:only_path => false)

Answer 19

In Rails 3 you can use

request.original_url

http://apidock.com/rails/v3.2.8/ActionDispatch/Request/original_url

Answer 20

you can use any one for rails 3.2:

request.original_url
or
request.env["HTTP_REFERER"]
or
request.env['REQUEST_URI']

I think it will work every where

"#{request.protocol}#{request.host}:#{request.port}#{request.fullpath}"

Answer 21

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"

Answer 22

For Rails 3.2 or Rails 4 Simply get in this way "request.original_url" Reference: Original URL Method

For Rails 3 As request.url is deprecated.We can get absolute path by concatenating

"#{request.protocol}#{request.host_with_port}#{request.fullpath}"

For Rails 2

request.url

Answer 23

if you want to be specific, meaning, you know the path you need:

link_to current_path(@resource, :only_path => false), current_path(@resource)

Answer 24

For rails 3 :

request.fullpath

Answer 25

request.env["REQUEST_URI"]

works in rails 2.3.4 tested and do not know about other versions.

Answer 26

To get the request URL without any query parameters.

def current_url_without_parameters
  request.base_url + request.path
end

Answer 27

You can either use

request.original_url 

or

"#{request.protocol}#{request.host_with_port}" 

to get the current URL.

Answer 28

You can use:

request.full_path

or

request.url

Hopefully it will resolve your problem.

Cheers

Answer 29

You can set a variable to URI.parse(current_url), I don't see this proposal here yet and it works for me.

Answer 30

To get the absolute URL which means that the from the root it can be displayed like this

<%= link_to 'Edit', edit_user_url(user) %>

The users_url helper generates a URL that includes the protocol and host name. The users_path helper generates only the path portion.

users_url: http://localhost/users
users_path: /users
