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

You can use:

request.full_path

or

request.url

Hopefully it will resolve your problem.

Answer 2

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

Answer 3

In Ruby on Rails 3.1.0.rc4:

 request.fullpath

Answer 4

You can either use

request.original_url 

or

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

to get the current URL.

Answer 5

 url_for(params)

And you can easily add some new parameter:

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

Answer 6

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!
