How to skip a before_filter for Devise's SessionsController?

Question

I have a before_filter in my ApplicationController; that is, for every controller in my project.

How can I skip_before_filter

Answer 1

Before my colleague showed me the way I posted in my other answer, I did this. I'm posting this in case you think it's simpler.

class ApplicationController < ActionController::Base
  # ...
  before_filter :do_something

  def do_something
    unless params[:controller] == 'devise/sessions'
      # ...
    end
  end
end
