Method: Facebooker::Session#batch

Defined in:

lib/facebooker/session.rb

#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
