Ruby: Nicedit + Carrierwave for image uploads

image.rb

class Image < ActiveRecord::Base
  attr_accessible :f
  mount_uploader :f, ImageUploader
end

image_controller.rb

# Assumes that your field name in HTML is "image" and that the data is posted to a URL that triggers the create method below
class ImageController < ApplicationController
  skip_before_filter :verify_authenticity_token # This is a hack, but need it for now. TODO: add the CSRF token to the nicedit request
   
  def create
    a = Image.new
    a.send("f=", params[:image]) # This tripped me up! Can't directly assign a.f = params[:image]
    a.save!

    if a.errors.any?
      # TODO SOMETHING
    else
      # This also tripped me up, getting the exact right format that nicedit was expecting.
      # assumes that in your ImageUploader carrierwave class you have a version called "medium"
      render json: {upload: {
        links:{original: "#{a.f.medium.url}"}
      }}
    end

  end
end # close ImageController
