描述

Describe the bug in a sentence or two.

I'm trying to extract colors from an uploaded image, following the docs on utilizing cloudinary_transformation and an after_save on the model. Unfortunately, metadata seems to always be nil. Once the after_save callback has finished, then source.metadata is populated. This seems like a misplaced lifecycle callback or something.

Issue Type (Can be multiple)

  • Build - Cannot install or import the SDK
  • Performance - Performance issues
  • Behaviour - Functions are not working as expected (such as generate URL)
  • Documentation - Inconsistency between the docs and behaviour
  • Other (Specify)

Steps to reproduce

class PhotoUploader < CarrierWave::Uploader::Base
  include Cloudinary::CarrierWave
  cloudinary_transformation image_metadata: true, colors: true
end

class Photo < ApplicationRecord
  mount_uploader :source, PhotoUploader

  after_save :extract_colors

  def extract_colors
    # `source.metadata` is `nil`
  end
end
