Build a custom validator that ensures that no Contact’s last_name is Evil.
class Contact < ActiveRecord::Base
validate :evil_in_last_name
if last_name.include?("Evil")
errors.add(:last_name, " name already taken")
end
end

Courses Plus Student 26,868 PointsQuite closed, but you need to define a method for the validator; so wrap this block of code
if last_name.include?("Evil")
errors.add(:last_name, " name already taken")
end
into a method named evil_in_last_name
.
Final code should be like this
class Contact < ActiveRecord::Base
validate :evil_in_last_name
def evil_in_last_name
if last_name.include?("Evil")
errors.add(:last_name, " name already taken")
end
end
end
