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

you can get absolute url by calling:

request.original_url

or

request.env['HTTP_REFERER']

**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"

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][1]:**


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.

You can either use

request.original_url
or

"#{request.protocol}#{request.host_with_port}"
to get the current URL.

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

You can add this [current_url](

[To see links please register here]

) method in the ApplicationController to return the current URL and allow merging in other parameters

#

[To see links please register here]

# + current_url( :page => 3 )
# =

[To see links please register here]

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

For Rails 3.x and up:

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

For Rails 3.2 and up:

request.original_url

Because in rails 3.2 and up:

request.original_url = request.base_url + request.original_fullpath

You can use the ruby method:

:root_url

which will get the full path with base url:

localhost:3000/bla
