Some CoffeeScript (verbosely commented for clarity)

# Override Rails handling of confirmation

$.rails.allowAction = (element) ->
  # The message is something like "Are you sure?"
  message = element.data('confirm')

Tested on: Rails 3.1, Mongoid 2.0.1, pg 0.12.0 gem

Migrate from Mongo to PG
1. remove mongoid gem
2. add pg gem
3. in application.rb re-add ActiveRecord
4. for all models
- inherit from ActiveRecord::Base
- get rid of Mongoid:Document line
- make migrations and put fields there

    user = User.new(params[:user])
    if user.save
      render :json=> user.as_json(:auth_token=>user.authentication_token, :email=>user.email), :status=>201
      return

Note that this validation runs both after the file is uploaded and after CarrierWave has processed the image. If your base uploader includes a filter to resize the image then the validation will be run against the resized image, not the original one that was uploaded. If this causes a problem for you, then you should avoid using a resizing filter on the base uploader and put any specific size requirements in a version instead.

So instead of this:

require 'carrierwave/processing/mini_magick'

Deploying Rails to Linode

Installing Ruby Enterprise Edition, Apache, MySQL, and Passenger for deploying Rails 3.0 applications.

Get a Linode, and set it up with Ubuntu 10.04 LTS so that you have till April 2013 to get updates. Once the Linode is formatted, boot it and continue on.

Set up an 'A' record in your DNS, pointing to the IP of your Linode. I'm using demo.napcs.com here.
