Question

I’m creating a Rails 3 Application that uses Carrierwave & Amazon S3. The Problem that I’m running into is that when Carrierwave uploads images to Amazon it’s setting the Content-Type to Application/Octet-Stream instead of it’s actual content type.

class ImageUploader < CarrierWave::Uploader::Base

  include CarrierWave::MiniMagick
  storage :fog
  process :resize_to_limit => [100, 75]
  process :convert => 'png'

end

From https://github.com/jnicklas/carrierwave/issues/284#issuecomment-1925631:

1. Add require 'carrierwave/processing/mime_types' to an initializer or your uploader(s).
2. Add include CarrierWave::MimeTypes to your uploader.
3. Add process :set_content_type to your uploader(s).
