Is it possible to catch exceptions raised in callbacks like after_create in the controller?

Of course. Those callbacks are synchronous, so the controller will catch those exceptions.

Is there a way to create a callback in Python?

Also is there a way to detect if the user presses a key in Python that works on most OS's? I've only seen 1 method and that only works in Python 2.6 and less. If you get the key, can you store it in a variable?

Where to put the d3.js source and my .json data so that rails will serve it

I'm trying to use D3, a javascript data visualization library in my rails app. The problem is that I can't figure out where to put the d3.js source and my .json data so that rails will serve it.

My problem is in the way d3 issues a GET request when it looks for my json and d3.js files.

Things I tried:- setting up a static pages folder that is served with high_voltage gem. This didn't work for me as I couldn't get around my application layout so it wrapped my js and json in html. I think this is why this didn't work.- putting the files to be served in the public folder. This didn't work because it couldn't find the routes for the public folder. I did turn on config.serve_static_assets in the production enviroment config file.
I feel like this question should have a simple answer as everything works perfectly if I put my html, json and d3.js files into a folder and start a simple python http server in that folder. I think my problem is in my understanding of the way rails is trying to serve things.

What is the best method to manage image uploads in Rails

What is the best method to manage image uploads in Rails? Is there a tool that allows auto-resizing upon image upload based on predefined dimensions? Moreover, is there any tool available that makes it possible to render / regenerate the same originally uploaded image using alternative view based styles, e.g. thumbs, 320x200 or 640x480 etc..?
