**How do we encapsulate cuntionality? 
The goal of encapsulation is making sure that code is only where it really belong and only exposed thru interface and hidden to outside world



View - content of page minus header and footer (which are in Main) knows how to render stuff; how things are laid out; show content. View only knows what the controller tells it. Actions& instance variables in the controller tell views what to do

Helper - Modules/classes that do useful things that may have no logical home. How does the view know about helpers? View knows about helpers thru rails magic. General purpose fuctions used across the application. Scoring 

Partial - is an HTML snippet 

Controller - capture information. Keep the controller lean. Does API calls as response from a route. (API calls go in the controller)



When to use helpers vs. 

Routes config

    --> controller method

Controller responds to routes. Routes map to controllers. And controller calls out to API. 

Use: score, transform, and compute for API calls.

Does view know about models? No. But controller does. 

Model: encapsulates data & provides to the controller and object oriented view. 

***What sorts of methods go into a model?

What is difference between score method in helper vs. score method in API?

APIs

Data

public

calculate ()
score ()


private is the keyword in Ruby

method = private def my_method

API calls controller

Random methods (helper or model)
