Extend Class

This feature also available for component.

First you must define your class before initializing the model

class MyClass{
    // This will be called when the model scope was initialized
    // and before calling `My.init`
    static construct(){
        // this.abc === 1
        this.hello = 2;
    }

    method(number){
        console.warn(number + " + 1 = ", number + 1);
    }
}

Or define your class with function so you can also define the model first

function MyClass(){}
MyClass.construct = function(){
    this.hello = 2;
};
MyClass.prototype.method = function(number){
    console.warn(number + " + 1 = ", number + 1);
};

Define an model while extending our class.

sf.model('something', {extend: MyClass}, function(My){
    My.abc = 1;

    // Called after static construct on the class
    My.init = function(){
        // My.hello === 2
        My.method();
    }

    My.method = function(){
        console.log("2");

        // You can also call method from the class with similar name
        this.super(2);
    }
});
