Welcome to FlatMDb, our awesome movie database! We have three models - Movie, Actor, and Role. A Movie has many Actors through Roles.
Before you start - sketch out the domain models, and think about how they connect.
- Classes vs Instances
- Variable Scope ( Class, Instance, Local )
- Object Relationships
- Arrays and Array Methods
- Class Methods
Your goal is to build out all of the methods listed in the deliverables. Do your best to follow Ruby best practices. For example, use higher-level array methods such as map, select, and find when appropriate in place of each
We've provided you with a console that you can use to test your code as well as some seed data. To enter a console session, run ruby run.rb from the command line. You'll be able to test out the methods that you write here.
Remember! This is a code challenge without tests. You cannot run rspec you cannot run learn. Make sure your associations and methods work in the console before submitting.
Actor#name- returns a string that is the actor's name
- Once a actor is created, their name cannot be changed.
Actor#age- returns an integer for the actor's age
Actor#rank- returns a string representing the actor's rank
- valid ranks are: "A", "B", "C", "D", and "E"
Actor.all- should return all of the actor instances
Actor.average_age- should return the average age of all actors in the database
Actor.a_list- should return an array of all actors with a rank of "A"
- BONUS
Actor#lie_about_age- given an integer of an age, change the actor's age AND rank
- if the new age is higher than their actual age, their rank should go down; if it's lower, their rank should go up
Movie#title- returns a string that is the movie's title
Movie#year- returns an integer that is the year the movie was released
Movie#box_office- returns a integer that is the amount of money the movie made at the box office
Movie#within_five_years- return an array of movies that have a release year that is either five years later or five years less than the movie instance calling this method's release year
- Example: I am movie 1 and I was released in 2000. If you have a release year of 1995-2005, you should be included, but don't include the movie calling it!
Movie.all- returns an array of all the movies
Movie.blockbusters- return an array of all movies that made over $50 mil
Movie.box_office_total_by_year- Given a year, return an integer representing the sum of all the movies' box office earnings in a given year
Role#actor- returns the actor object for that given role
- Once a role is created, I should not be able to change the actor
Role#movie- returns the movie object for that given role
- Once a role is created, I should not be able to change the movie
Role#name- returns a string that is the character's name
Role#earnings- returns a number representing the percentage of the movie's box office earnings that the actor gets paid
- This should be a float that is not a negative number.
Role.all- returns all of the roles
Actor#sign_contract- given a movie object, character name (as a string), and their earnings percentage (as a float), creates a new role and associates it with that movie and actor.
Actor#total_roles- Returns the total number of roles that the actor has had
Actor#movies- Returns all the movie instances the actor has been in
Actor#blockbusters- Returns all the movie instances the actor has been in that made over $50 mil
Actor#total_earnings- Returns a number representing the actor's total earnings for all their roles
- HINT: you will have to calculate the actor's earning for each role using their earnings percentage and the movie's box office total
Actor.most_successful- Return the actor whose films have made the most money
Movie#cast_role- given an actor instance, character_name, and earnings, create a new role for them in this film
Movie#stars_by_rank- return a list of actors in this movie sorted by their rank
