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'

# Simple bijective function
#   Basically encodes any integer into a base(n) string,

#   Based on pseudocode from http://stackoverflow.com/questions/742013/how-to-code-a-url-shortener/742047#742047

ALPHABET =
  "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".split(//)
  # make your own alphabet using:
  # (('a'..'z').to_a + ('A'..'Z').to_a + (0..9).to_a).shuffle.join

# You can use this class in your console. For example
#   p = ProfilingTools.new
#   p.profiled_request(:controller => :welcome, :action => :index)
# this will profile whole application stack and save file in your tmp/profiler folder
# You can also use +request+ method just to see the output for example:
#
#   p.request(:controller => :offers, :action => :index)
#   
#   p.response.body
#   p.response.cookies # and so on
