Custom Validation challenge..

so the challenge is to build a custom validation to ensure no last_name is evil.. this is my code and it is prettywell exact to the video without the validations..

My CODE: 

 class Contact < ActiveRecord::Base

   validate: name_is_not_evil

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

all i get it Bummer.. Try Again this is getting ridiculous. thanks for the help in advance.

You are very close, just move the colon from validate to :name_is_not_evil

validate :name_is_not_evil

This should help you: http://guides.rubyonrails.org/active_record_validations.html#custom-methods

Hi Shawn,

I found minor semi-colon mistake right there under validate line. 

   validate: name_is_not_evil

Here's better example to meet the challenge question without extra codes, see below

class Contact < ActiveRecord::Base

   validate :name_has_no_evil

   def name_has_no_evil
     if last_name.include?("Evil")
       errors.add(:last_name, "Can not be Evil")
     end
   end
 end

Hope that helps :)
