What API to use for uploading images to a Rails based website from an iPhone application? [closed]

Looking at using either ObjectiveResource or ASIHTTPRequest ...

1. Which is superior for uploading images? Or is there a better option???

2. Are there any examples of using either or both to upload images (or any other binary content)?

Thanks

No route matches "/sessions.json

So why would I be getting this error and why its pointing to localhost instead of localhost:3000?

Completed in 27ms (View: 3, DB: 13) | 406 Not Acceptable [http://localhost/sessions.json]

I am trying to use ObjectiveResource (iphone app) and Rails. ObjectiveResource points to sessions.json with a Post I guess when creating a session.

In my routes file I am using

map.resources :sessions map.connect ':controller.:format'
map.connect ':controller/:action.:format'

Can anyone tell me what is going on in this error code? Man apple is cryptic. I have just made a call via ObjectiveResource to data I know is fine.

Up to date alternative to ObjectiveResource for iPhone+Rails?

I'm creating a Rails app with an iOS client and found ObjectiveResource. It looks awesome for CRUD operations, but it hasn't been updated since 2009 so it seems built for rails2 and the first iphone sdk. Does anyone know of a similar but up to date framework?

ObjectiveResource-style framework for communicating with Python?

I recently came across ObjectiveResource and it appears to be a fantastic tool. All my back-ends are written in Python, and I don't have a lot of experience with Ruby nor Rails. Is there a similar project for Python?

Communication between iPhone App and Rails App

What is the best way to communicate between an iphone app and a rails web app? I need to be able to register as a user, edit my profile and upload, rate and comment images in the rails web app.

In my rails controllers I have a lot of stuff (logic), I don't need when communicating with an iphone. How can I separate the logic for the iphone and the web in my controller? Should I use separate controllers for web and iphone communication?

What's the best tool/framework on the iphone to exchange data and images with a rails app? I looked at ObjectiveResource, but I'm not sure if it will to the trick (including image uploads).
