Up until this point, our controllers have consisted of only fixture, or fake, data, so we can prove that our controllers are working and our view models were wired up to our templates. The next logical step in our development is to populate our View models with data directly from MongoDB. It would be even better if we could just pass our Mongoose models right to our templates as viewModel itself.
