module DeviseHelper
  # A simple way to show error messages for the current devise resource. If you need
  # to customize this method, you can either overwrite it in your application helpers or
  # copy the views to your application.
  #
  # This method is intended to stay simple and it is unlikely that we are going to change
  # it to add more behavior or options.
  #
  # Overridden in DRI to use flash messages for consistency with the rest of the application
  #
