Currently I have followed these instructions to get aws s3 working in  
my rails app

[http://developer.amazonwebservices.com/connect/entry.jspa?entryID=608](http://developer.amazonwebservices.com/connect/entry.jspa?entryID=608)

But its a little messy as a lot of the file uploading is actually done  
in the controller when I think it should be done in the model.  
Currently its done like this

class PhotoController \< ApplicationController  
before\_filter :login\_required  
layout ‘scaffold’

#load model  
model :s3\_model

#create S3::AWS handle  
S3Model.init(@config\_file)

The current files to load in the aws are:  
/lib/S3.rb (ruby library to connect to aws)  
/model/s3\_model.rb

What I would like to do is put all of the aws s3 calls in the model  
when uploading a photo. I’m thinking instead to do this…

class ApplicationController \< ActionController::Base  
include S3  
model :s3\_model

#create S3::AWS handle  
S3Model.init(@config\_file)

But if I do this… this would only given accessibility to the aws  
handler in the controller and not the model right?

If I had a class ProfilePicture \< ActiveRecord::Base how would I give  
the aws handler visibility there?

thanks in advance!
