I am doing some exception handling in my controller, when there is an exception thrown in :create action, I will render to the :new action and show a flash message.
Everything works fine, I can see the flash message when exception caught, but when I redirect to(handly click) other page, the flash message still here. Then I redirect to another page(the second handly click), the message could disappear.
Anyone who knows what is the reason?
My controller code:
class MessagesController < ApplicationController rescue_from Exception, :with => :render_new def new end def create end private def render_new flash[:alert] = t("uploading_error") render :action => :new end end
My layout code (Haml):
%body #content - unless flash[:alert].blank? #alert= flash[:alert]
