I\'m using devise for authentication and have some before_filters in my application controller. Issue I\'m seeing is that when I try to logout the before_filter intercepts t
You can qualify a filter with :only or :except.
before_filter :filter_name, :except => [:action1, :action2]
Or if the filter (as I now see is the case in your situation) is defined in ApplicationController and you want to bypass it in a subclass controller, you can use a skip_before_filter with the same qualifications in the subclass controller:
skip_before_filter :filter_name, :except => [:action1, :action2]
