Models In-Depth

In this article, you will get a deeper understanding of the inner workings of models, and how you can use them to write better code.

How attributes are resolved

If you are accessing a property, for example post.author this call goes through a variety of methods.

1. Getters / Setters

If there is a getter defined for this property on the model, call the getter. This getter could look like this:

class Post {
    get author() {
        return 'written by ' + this.attributes.author
    }
}

2. Live Attributes

If there is no getter or setter, redirect the call to the getter or setter of post.attributes. post.attributes is an object, which has a getter and setter for each of your attributes.

3. Finally Getting the attribute

post.attributes.post is a getter, which calls post.getAttribute('author').
