mech / education.rb
Last active Dec 15, 2015
Trying to see how DDD can help in modeling ATS's Education model.
View education.rb
# Entity - Represent an important domain concept with identity and life cycle.
class Education
def initialize(institution, course, when)
@institution = # Institution is an Value Object that is immutable
@course = Course.for(course) # Course is an Value Object too
@period = period(when) # PostgreSQL's daterange Range Type
def course_ended? # Query method - Based on period, is CA still studying?
You can’t perform that action at this time.
