Ruby ActiveRecord Basics Validation Errors 2

Having trouble with custom validation

class Contact < ActiveRecord::Base

   validate :last_name_not_evil

   def last_name_not_evil
     if last_name.include?("evil")
       errors.add(:name, "cannot be evil")
     end
   end
 end

Requirement is to build a custom validation that ensures last_name is not Evil.

I keep getting "bummer"'ed, though.

Anything I'm missing?

They want "Evil", not "evil" and they want last_name attribute, so:

     if last_name.include?("Evil")
       errors.add(:last_name, "cannot be evil")

Very, very tired. Thanks for the catch. :)

I actually pasted one of the futile frustrated attempts where I was changing things I didn't think mattered, like the case.

I had most things right most of the time, except I never changed the symbol to last_name.

I'll try sleeping sometime this week, see if I can avoid some of the sillier stuff,

Yeah, sleep might help - you have to pay attention to every space (literally) when coding :)
