##Quiz: Lesson 3 Solutions

####1. What's the difference between rendering and redirecting? What's the impact with regards to instance variables, view templates?

Rendering displays a view template that accesses the instance variables available in that action. Therefore, instance variables must be declared in that action before the render will work. Redirecting will send a new request to the browser based on the route path that was provided. In this case, the instance variables in that action are not related to the redirected view.

####2. If I need to display a message on the view template, and I'm redirecting, what's the easiest way to accomplish this?

You can use flash, which saves the message with a session. The message will be displayed on your next action and will be removed after that. flash[:message] = 'Your account was created.' redirect_to :back

You will need your credit card for doing this. It's free to use but be forewarned, be careful not to push your AWS credentials up to any public domains or somebody could use your credit card.

Before we begin let's get our app setup for Amazon Web Services(AWS):
