Question

我正在制作一款能够让用户上传图片的rails应用程序。现在它只使用paperclip，它在我的系统/用户本地保存图像。

现在，我希望能够将图像上传到S3。我配置了我的水桶，并安装了aws-sdk宝石，所以亚马逊方面也下降了。

我在线阅读了多个来源，但迄今为止都没有。这是我目前拥有的

user.rb

has_attached_file :image_1, 
                  :storage => :s3,
                  :s3_credentials => Proc.new{ |amazon| amazon.instance.s3_credentials }
validates_attachment_content_type :image_1, :content_type => { :content_type => ["image/jpeg", "image/gif", "image/png", "application/pdf"] }

has_attached_file :image_2, 
                  :storage => :s3, 
                  :s3_credentials => Proc.new{ |amazon| amazon.instance.s3_credentials }
validates_attachment_content_type :image_2, :content_type => { :content_type => ["image/jpeg", "image/gif", "image/png", "application/pdf"] }

def s3_credentials
  {:bucket => "bucketname", 
   :access_key_id => "1234", 
   :secret_access_key => "1234"}
end

aws.yml

test:
  access_key_id: key
  secret_access_key: secret
development:
  access_key_id: key
  secret_access_key: secret
production: 
  access_key_id: key
  secret_access_key: secret

development.rb，production.rb，test.rb

  config.paperclip_defaults = {
   :storage => :s3,
   :s3_host_name => 's3-website-us-west-2.amazonaws.com'
 }

users_controller.rb

def new
  @user = User.new
end

def create
  @user = User.new(user_params)
  if @user.save
    redirect_to '/'
  else
    render 'new'
  end
end

def user_params 
  params.require(:user).permit(:image_1, :image_2)
end

**这是我提交表格时的堆栈跟踪**

我还阅读了一些资源，说我可能需要一个初始化文件，但这似乎也不起作用。如果有人有这方面的经验，我将不胜感激听到你的建议。
