我正在使用Carrierwave版本1.0.0rc将文件上传和处理到AWS S3存储桶。这是我的环境:
Rails 4.2.0 Ruby 2.1.1 MiniMagick 4.5.1 ImageMagick 6.9.7-0
我的上传器确定要上传的原始图片是横向还是纵向,并相应地应用处理规则。该文件上传到AWS S3存储桶,但随后出现以下错误:
Errno :: ENOENT in SponsorsController #create 没有这样的文件或目录@ rb_sysopen - uploads / sponsor / logo / 30 / Breen_Electrical_Logo.jpg
并且提取的源代码突出显示了此代码:
image = MiniMagick::Image.open(picture.path)
以下是我的上传代码:
class LogoUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
storage :fog
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
version :landscape, if: :is_landscape?
version :portrait, if: :is_portrait?
version :landscape do
process resize_to_fit: [200, 50]
end
version :landscape_sm, from_version: :landscape do
process resize_to_fit: [100, 25]
end
version :portrait do
process resize_to_fit: [50, 200]
end
version :portrait_sm, from_version: :portrait do
process resize_to_fit: [25, 100]
end
private
def is_landscape? picture
image = MiniMagick::Image.open(picture.path)
image[:width] > image[:height]
end
def is_portrait? picture
image = MiniMagick::Image.open(picture.path)
image[:width] < image[:height]
end
end
私有方法似乎打开文件来比较它的宽度和高度值。当我将文件存储在本地公用文件夹中时,这很好用。我在猜测&#34; picture.path&#34; url未指向S3存储桶路径以打开文件。
这是我的/config/initializers/carrierwave.rb文件
require 'fog/aws'
CarrierWave.configure do |config|
config.fog_provider = 'fog/aws'
config.fog_credentials = {
provider: 'AWS',
aws_access_key_id: <access_key_id>,
aws_secret_access_key: <secret_access_key>,
region: 'us-west-2',
:path_style => true
}
config.fog_directory = <bucketname>
end
我似乎无法找到其他人遇到同样的问题。有任何想法吗?提前谢谢。

我认为您需要直接引用该文件,而不仅仅是路径,因为它不是本地的。类似的东西:
ruby
image = MiniMagick::Image.open(picture.file)
