Could not get my custom validator to work on the second challenge

validate :evil_in_name

def evil_in_name
    if last_name.include?("evil")
        errors.add(:last_name, " is evil")
    end
end

The challenge says "Evil", not "evil". You can either put this capitalized word in the parentheses after "include?" or chain a .downcase before the "Include?"

OMG, I can't believe that was it! Here I was racking my brains checking every letter of the actual ruby code, it didn't even occur to me to look at upper/lower case on the actual string. Thanks, boy I feel dumb.

This this challenge, another way is to use validates (with the "s") and the exclusion parameter. Here's the documentation that shows its usage: http://edgeguides.rubyonrails.org/active_record_validations.html#exclusion

Oh, and for motivated individuals, here's three more ways to do string validation :)
