Office Lab

​ 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. You are being asked to create a three domain models - a Manager model, a Employee model, and a Role model and build out their relationships!

Here are some questions to consider: ​

• What are your models?
• What does your domain look like?
• What are the relationships between your models?
• Which model should know about the other in its initialization? ​

Before you start

1. Run bundle to install gems
2. In order to test your code run from the root directory ruby tools/console.rb
3. Write all your test code in the console.rb file ​

Here are our deliverables:

Keep in mind that in order to properly build out the relationships between the three models, one of these classes will be instantiated with objects of others. This will not be mentioned in the description below, you need to deduce it on your own. Consider where and how this dependency needs to be implemented. ​

Manager

• Manager is initialized with a name, department and age. All of these attributes can change.
• Manager#name

• Manager#roles
  • returns an Array of all the roles that the manager oversees
• Manager.all
  • returns an Array of all the managers
• Manager.all_departments
  • returns an Array of all the department names that every manager oversees without repetitions

• Employee#salary
  • returns a Fixnum that is the employee's salary
• Employee#manager
  • returns an instance of their manager
• Employee#role
  • returns an instance of their role
• Employee.all
  • returns an Array of all the employees

Role

• Role is initialized with a name, which won't ever change.
• Role#name

  • returns a unique array of all the Manager instances who oversee Employees at that role
• Role.all
  • returns an Array of all the roles
• Role#add_employee
  • takes a String argument of an employee's name, a Fixnum argument of the employee's salary and an instance of a Manager class and creates a new employee who work at this role
