Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
| 1 | # frozen_string_literal: true |
||
| 4 | class StudyParticipant < ApplicationRecord |
||
| 5 | belongs_to :participant, inverse_of: :study_participants |
||
| 6 | belongs_to :study, inverse_of: :study_participants |
||
| 7 | validates :participant, presence: true |
||
| 8 | validates :study, presence: true |
||
| 9 | |||
| 10 | validates_uniqueness_of :study, scope: :participant |
||
| 11 | validates_uniqueness_of :participant, scope: :study |
