  :title     => text,
  :content   => text,
  :published => created_at,
  :verb      => :post
  ) do |entry|
  entry.has_author user.name, user.url
  entry.has_obj do |activity_obj|
    activity_obj.id        = id
    activity_obj.title     = text
    activity_obj.published = created_at
    activity_obj.updated   = created_at
    activity_obj.author    = entry.author

def adapt *args, &block
  hsh = args.extract_options!
  args_hsh = Hash.zip(self.members[0...args.length], args)
  self.attributes = hsh.merge(args_hsh)
  yield self if block
end

#attributes=(hsh) ⇒ Object

for each key in hsh, sets that attribute to the corresponding value.

Examples:

foo
# => #<Struct Simian name="Mojo Jojo" status="villain" nemesis=nil species='Chimpanzee'>
foo.attributes = { :nemesis => 'Powerpuff girls', :species => 'Pan Troglodytes' }
foo
# => #<Struct Simian name="Mojo Jojo" status="villain" nemesis='Powerpuff Girls' species='Pan Troglodytes'>
