In this project, you will get the chance to practice object relationships in Ruby, with a particular emphasis on the has_many/belongs_to relationship. Make sure you read the entire README and map out your domain models before writing any code!

Welcome to your first day at the Flatiron Mifflin Paper Company. As the Assistant to the Regional Manager, your job is to implement the new Office Management System for both the employees and their managers. Since Michael (your boss) has personally tasked you with this job, you can't disappoint.

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. 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. Take a look at that file to see how you can pre-define variables and create object instances, rather than manually doing it in every single console session.

There are no tests! You will need to test your code on your own!

First step to this problem is to consider your domain. At Flatiron Mifflin, an Employee can only work in one department and a Manager oversees only one department. There are often many Employees working for one Manager because if there are two Managers to "microgement" one employee, the employee might become "aggressive", "hostile" or "difficult."

Here are some questions to consider:

• What are your models?
• What does your domain look like?
• What are the relationships between your models?

Manager

• Manager#name
  • returns a String that is the manager's name
• Manager#department
  • returns a String that is the department that the manager oversees
• Manager#age
  • returns a Fixnum that is the age of the manager
• Manager#employees
  • returns an Array of all the employees that the manager oversees
• Manager.all
  • returns an Array of all the managers
• Manager#hire_employee
  • takes a String argument and a Fixnum argument of an employee's name and the employee's salary, respectively, and adds that employee to the list of employees that the manager oversees
• Manager.all_departments
  • returns an Array of all the department names that every manager oversees
• Manager.average_age
  • returns a Float that is the average age of all the managers

Employee

• Employee#name
  • returns a String that is the employee's name
• Employee#salary
  • returns a Fixnum that is the employee's salary
• Employee#manager_name
  • returns a String that is the name of their manager
• Employee.all
  • returns an Array of all the employees
• Employee.paid_over
  • takes a Fixnum argument and returns an Array of all the employees whose salaries are over that amount
• Employee.find_by_department
  • takes a String argument that is the name of a department and returns the first employee whose manager is working in that department
• Employee#tax_bracket
  • returns an Array of all the employees whose salaries are within $1000 (± 1000) of the employee who invoked the method
