During day three, all the layers of a MVC architecture were shown and modified to have the list of questions properly displayed on the homepage. The application is getting nicer but still lacks content.
The objectives for the fourth day are to show the list of answers to a question, to give a nice URL to the question detail page, to add a custom class, and to move some chunk of codes to a better place. This should help you understand the concepts of template, model, routing policy, and refactoring. You may think that it is too early to rewrite code that is only a few days old, but we'll see how you feel about it at the end of this tutorial.
