Here's what's going on: every Rails model can be initialized with its
respective attributes, which are automatically mapped to the respective
-database columns. In the first line we do just that (remember that
-`post_params` contains the attributes we're interested in). Then,
-`@post.save` is responsible for saving the model in the database.
-Finally, we redirect the user to the `show` action,
-which we'll define later.

-TIP: Note that `def post_params` is private. This new approach prevents an attacker from setting the model's attributes by manipulating the hash passed to the model. For more information, refer to [this blog post about Strong Parameters](http://weblog.rubyonrails.org/2012/3/21/strong-parameters/).
