#batch(serial_only = false) ⇒ Object

Submit the enclosed requests for this session inside a batch

All requests will be sent to Facebook at the end of the block each method inside the block will return a proxy object attempting to access the proxy before the end of the block will yield an exception

For Example:

facebook_session.batch do
  @send_result = facebook_session.send_notification([12451752],"Woohoo")
  @albums = facebook_session.user.albums
end
puts @albums.first.inspect

is valid, however

facebook_session.batch do
  @send_result = facebook_session.send_notification([12451752],"Woohoo")
  @albums = facebook_session.user.albums
  puts @albums.first.inspect
end

will raise Facebooker::BatchRequest::UnexecutedRequest

If an exception is raised while processing the result, that exception will be re-raised on the next access to that object or when exception_raised? is called

for example, if the send_notification resulted in TooManyUserCalls being raised, calling 

@send_result.exception_raised?

would re-raise that exception if there was an error retrieving the albums, it would be re-raised when 

@albums.first

is called

#create_event(event_info, multipart_post_file = nil) ⇒ Object

Creates an event with the event_info hash and an optional Net::HTTP::MultipartPostFile for the event picture. If ActiveSupport::TimeWithZone is installed (it’s in Rails > 2.1), and start_time or end_time are given as ActiveSupport::TimeWithZone, then they will be assumed to represent local time for the event. They will automatically be converted to the expected timezone for Facebook, which is PST or PDT depending on when the event occurs. Returns the eid of the newly created event wiki.developers.facebook.com/index.php/Events.create
