ruby on rails - uninitialized constant UploadsController::Bucket when trying to write general AWS::S3 Upload controller -

i'm trying write general amazon s3 uploader (will used images) rails project. able set environment in console following http://amazon.rubyforge.org/.

i able follow guide in console. however, had trouble when applied rails project. when try access new view, following error:

nameerror in uploadscontroller#new  uninitialized constant uploadscontroller::bucket 

here controller:

class uploadscontroller < applicationcontroller require 'aws/s3'    def new     photo_bucket = bucket.find('photos')     @photos = photo_bucket.objects   end    def create     file = 'black-flowers.jpg'     s3object.store(file, open(file), 'photos')   end end 

in controller, new action contain form upload , list of photos.

my create action save file. haven't figured out how params form passed controller yet, ignore 'black-flowers.jpg' line.

my guess did not establish connection in controller.

how establish connection or fix error?

thanks looking.

bucket not top level constant in case. want aws::s3::bucket constant new, , i'd assume similar s3object.

note may want fog library this.

the fact haven't figured out how params passed in implies may want work through rails tutorials without s3 first.
