2nd Validation Quiz

Here is the question

Build a custom validator that ensures that no Contact’s last_name is Evil.

Here is my answer:

lass Contact < ActiveRecord::Base

validate :last_name_is_not_Evil

def last_name_is_not_Evil if @last_name.include?("Evil") errors.add(:last_name, "is Evil") end end

I get the ole Bummer Try Again message. Am I missing something really obvious?

Thanks!

Hi Michael,

the following should work:

 class Contact < ActiveRecord::Base
   validate :last_name_is_not_evil
 end

def last_name_is_not_evil
  if last_name.include?("Evil")
    errors.add(:last_name, "is Evil")
  end    
end

It was a simple error on capitalizing "Evil" in the method name. The way you had it would have worked technically, but typically in Ruby we don't use capitalizations in method names so the test was actually reacting to the style more than the substance.
