Ajax login and confirmable

[Hinrik Örn Sigurðsson]

I have a login form which pushes some JS to the user if their credentials are invalid. I do this by overriding SessionsController#create like so:

  def create
    if request.format == 'js' && params[:region] && params[:region] == 'inline'
      resource = warden.authenticate(auth_options)
      if warden.authenticated?
        sign_in(resource)
        current_user.remember_me!
        path = after_sign_in_path_for(resource)
        render :update do |page|
          page.redirect_to path
        end
      else
        render partial: 'sessions/login_failed'
      end
    else
      super
    end
  end


However, when using confirmable, if an unconfirmed user enters their email and the right password, Devise handles the error itself (401 along with a message telling the user to confirm) before my #create is able to handle it. How can I modify my code so that it also handles the case when an unconfirmed user tries to log in? I'm aware of the custom failure app method, but that seems to be even more hacky. I.e. I can't call render() from there. Ideally I'd like to be able to push some JS to the user in both situations (wrong password, unconfirmed user), containing appropriate messages for each (e.g. the respective Devise flash error message).
