Overview

Where we've been

school = School.new('Flatiron School') school.students => ["Isaac", "Caroline", "Zahran"]

student = Student.new('Isaac') student.school -> "Flatiron School"

Where we'll be from here on out

school = School.new('Flatiron School') school.students => [<Student @name="Isaac">, , ]

student = Student.new('Isaac', School.new('Flatiron School')) student = Student.new(String.new('Isaac'), School.new('Flatiron School')) student.school

Objectives

• Object relationships, has many/belongs to
• Single source of truth

Deliverables

1. Create a User class. A user should initialize with a username and have a reader and writer method for the username. A user should have a method called #tweets that returns an array of Tweet instances.
2. Create a Tweet class. A tweet should have a method called #message that points to a string and #user that points to an instance of the user class. It should have a method called .all that returns all the Tweets created.
3. Tweet instances should respond to a message called #username that returns the username of the tweet's user.
4. User instances should respond to a method called #post_tweet that takes in a message, creates a new tweet and adds it to that user's collection.
