// # Base Model
|

// This is the model from which all other Ghost models extend. The model is based on Bookshelf.Model, and provides

// several basic behaviours such as UUIDs, as well as a set of Data methods for accessing information from the database.

//
|
|
// The models are internal to Ghost, only the API and some internal functions such as migration and import/export
|
|
// accesses the models directly.
|
|
|
|
// All other parts of Ghost, including the frontend & admin UI are only allowed to access data via the API.
