Overview

This video gives an overview of object models and how to make our classes more powerful.

Create a class and add reader and writer methods
Define class methods with an explicit self receiver
Capture new instances of self in the initialize method
Use a class variable or constant to hold the instances of the class
Explain why we avoid using the return keyword from within a loop
Define a find_by_location method to find a particular instance of a class
Abstract the logic of the find_by_location method to a detect enumerable method
Define a class method find_all_by_location to find all instances with that location using the select enumerable method
Define a custom constructor method to create instances from attributes scraped from a website

This video also covers many of the above topics in the main lesson video. Feel free to use this as another refresher on object models.
