New models are updating when they should be creating

[josephmancuso]

When you new up a model that has no data inside it it is updating. These models should be creating.

For example, when you do something like this:

user = User()
user.name = "bill"
user.save()

It is currently doing an update. But failing because there is nothing to update. This should instead be doing an insert. We can check if the model is loaded or not loaded and either update or create
