$ngResource is kinda a pain. It lacks a lot of common features. There are a ton of alternatives but they are either heavy or don't really fit the AngularJS pattern.
In the search for the perfect model for Angular, I kept coming up short. So I decided to take the challenge face on.
I give you angular-model-factory. It implements the same pattern as ngResource but adds everything it should have!
