#initialize(data) ⇒ Model

Constructor

Keys from the data parameter will be converted into instance variables with getters and setters in place. The data parameter can be an Array of length of the defined fields or without the primary key. The order needs to be the same as the defined fields. The primary key has no setter, but adds a getter called pk for convenience.

param data:

Hash of String => Objects or Array of Objects
