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

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  gt  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   gt  remote
