CarrierWave没有将文件上传到s3，而是缓存(Heroku上的Sinatra应用程序)

Question

我有一个Sinatra应用程序，它接收一张图像，并试图将其上传到s3。我收到的回复说模型已成功保存，但保存时返回的图像URL是缓存的上传。s3存储桶中也没有显示任何图像。代码如下，是否存在明显错误？我一直在关注Railscast#383集上传到s3。

任何帮助都是感激的，我已经尝试了很多事情，但都无济于事。

app.rb

before do
#Configure Carrierwave
CarrierWave.configure do |config|
config.storage = :fog
config.fog_credentials = {
provider: "AWS",
aws_access_key_id: ENV['s3_access_key_id'],
aws_secret_access_key: ENV['s3_secret_access_key']
}
config.fog_directory = ENV['s3_bucket']
config.fog_public = true
end
end
post "/nominations" do
image = params[:file] || nil
nomination = Nomination.create({
image: image
})
if nomination.valid?
nomination.save
status 201
body nomination.image.url
else
status 500
body nomination.errors.messages.to_s.to_json
end
end
end

image_uploader.rb

require "carrierwave"
require 'carrierwave/storage/fog'
class ImageUploader < CarrierWave::Uploader::Base
storage :fog
def extension_white_list
%w(jpg jpeg gif png)
end
end

提名.rb

class Nomination < ActiveRecord::Base
extend CarrierWave::Mount
attr_accessor :image
mount_uploader :image, ImageUploader
end

我直接通过s3:上传

image = params[:file] || ''
uri = URI::Data.new(image)
filename = nom.id.to_s + "_" + Time.now.strftime('%Y%b%d_%H:%M:%S') + '.png'
s3 = Aws::S3::Client.new(
access_key_id: ENV.fetch('s3_access_key_id'),
secret_access_key: ENV.fetch('s3_secret_access_key'),
region: ENV.fetch('s3_region'),
)
response = s3.put_object(bucket: ENV.fetch('s3_bucket'), key: filename, body: uri.data, acl: "public-read")
image = "https://s3.amazonaws.com/" + ENV.fetch('s3_bucket') + "/" + filename
