# fails after one call even when not doing anything invasive at all:
Devise::PasswordsController.class_eval do
  # POST /resource/password
  def create
    # email is not unique, so iterate amongst all the users
    resource_class.where(:email => params[resource_name][:email]).all.each do |res|
      logger.info res.username
    end

    redirect_to new_session_path(resource_name)
