Every time I re-seed my database locally, duplicate images are being created in my Amazon S3 bucket. I think this is happening because I am not seeding correctly, but I don't know the proper way to do it. I've been using the method shown here. I'm using Rails 4, Ruby 2, paperclip 3.5.2, and aws-sdk 1.20.0.

You can see below in my seeds.rb file, I'm trying to set the image to the url of an image that has already been uploaded to the correct folder in my bucket. However, I think using open() here is causing a new, identical file to be saved to the same folder, usually something like http://s3.amazonaws.com/BUCKET_NAME/restaurants/images/1/original/open-uri20131111-22904-xvzitl.?1384211739.

EDIT: so my bucket will have both this file stored as well as http://s3.amazonaws.com/BUCKET_NAME/restaurants/images/1/original/NAME.jpg

Would really appreciate any help!

model

has_attached_file :image,
      :styles         => { :medium => "300x300>", :thumb => "100x100>" }

seeds.rb

Restaurant.create!( name:         ...,
                    description:  ...,
                    image:        open('https://s3.amazonaws.com/<BUCKET NAME>/restaurants/images/1/original/<NAME>.jpg') )

config/initializers/paperclip.rb

Paperclip::Attachment.default_options[:storage]         = :s3
Paperclip::Attachment.default_options[:s3_credentials]  = {
                                                            :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
                                                            :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
                                                          }
Paperclip::Attachment.default_options[:bucket]          = ENV['AWS_BUCKET']
Paperclip::Attachment.default_options[:url]             = ":s3_path_url"
Paperclip::Attachment.default_options[:path]            = "/:class/:attachment/:id/:style/:basename.:extension"
Paperclip::Attachment.default_options[:default_url]     = "https://s3.amazonaws.com/<BUCKET NAME>/images/missing.png"

我参加这个聚会已经很晚了，但我认为其他人可能仍然遇到同样的问题。如果在删除它们之前将模型上的附件设置为 nil，则回形针将从 S3 中删除它们。
