| UPDATE: Please see some of the forks for an updated version of this guide. I | |
| myself have moved onto the Rails 3.1 betas to get the asset pipeline. But if | |
| you want to stay on stable there are other folks who are keeping this guide | |
| relevant despite the changes constantly occurring on Sprockets 2. The comments | |
| on this gist will lead you to the right forks. :) | |
| Some brief instructions on how to use Sprocket 2 in Rails to get CoffeeScript | |
| powered JS and SASS powered CSS with YUI compression all via the magic of rack. | |
| This stuff will be native in Rails 3.1 and the layout of the files on the |
| # Add this | |
| public/javascripts/all.js |
| require 'matrix' | |
| def regression x, y, degree | |
| x_data = x.map {|xi| (0..degree).map{|pow| (xi**pow) }} | |
| mx = Matrix[*x_data] | |
| my = Matrix.column_vector y | |
| ((mx.t * mx).inv * mx.t * my).transpose.to_a[0].reverse | |
| end |
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'
