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

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

The request.request_uri only returns the relative URL.

For Rails 3.2 or Rails 4+

You should use request.original_url to get the current URL.

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.

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!

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

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

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

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

Using #request_uri is deprecated. Use fullpath instead.

In Ruby on Rails 3.1.0.rc4:

 request.fullpath

Peter Mortensen Reply to 2012-09-07 15:53:42Z

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

You could use url_for(:only_path => false)

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

root_url(:only_path => false)
Peter Mortensen

Peter Mortensen Reply to 2012-09-07 15:54:54Z
 url_for(params)

And you can easily add some new parameter:

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

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

request.env['REQUEST_URI']
msroot

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

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

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

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

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

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

In Rails 3 you can use

request.original_url

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

You can use the ruby method:

:root_url

which will get the full path: localhost:3000/bla

request.env["REQUEST_URI"]

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

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}"

To get the request URL without any query parameters.

def current_url_without_parameters
  request.base_url + request.path
end

Rails 4

Controller:

def absolute_url
  request.base_url + request.original_fullpath
end

Action Mailer Notable changes in 4.2 release:

link_to and url_for generate absolute URLs by default in templates, it is no longer needed to pass only_path: false. (Commit)

View:

If you use the _url suffix, the generated URL is absolute. Use _path to get a relative URL.

<%= link_to "Home", root_url %>

You can use:

request.full_path

or

request.url

Hopefully it will resolve your problem.

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

to get the current URL.
