  field :author
  field :body

  belongs_to :post

  validates :author, :body, :post, :presence => true

  after_create do
    puts "#{author} commented on #{post.title}"
  end
end

NoBrainer.purge!

post = Post.create!(:title => 'ohai', :body  => 'yummy')

puts post.comments.create(:author => 'dude').
  errors.full_messages == ["Body can't be blank"]

post.comments.create(:author => 'dude', :body => 'burp')
post.comments.create(:author => 'dude', :body => 'wut')
post.comments.create(:author => 'joe',  :body => 'sir')
