I need to know the current route in a filter in Rails. How can I find out what it is?

I'm doing REST resources, and see no named routes.

If you are trying to special case something in a view, you can use current_page? as in:

<% if current_page?(:controller => 'users', :action => 'index') %>

...or an action and id...

<% if current_page?(:controller => 'users', :action => 'show', :id => 1) %>

...or a named route...

<% if current_page?(users_path) %>

...and

<% if current_page?(user_path(1)) %>

Because current_page? requires both a controller and action, when I care about just the controller I make a current_controller? method in ApplicationController:

  def current_controller?(names)
    names.include?(current_controller)
  end

And use it like this:

<% if current_controller?('users') %>

...which also works with multiple controller names...

<% if current_controller?(['users', 'comments']) %>
