[英]Paperclip S3 download remote images
How I can download a remote image (http protocol, the url is in the image_remote_url attribute) and save it as an attachment to S3 via Paperclip ? 我如何下载远程图像(http协议,url在image_remote_url属性中)并通过Paperclip将其保存为S3的附件?
class Product < ActiveRecord::Base
require 'open-uri'
attr_accessor :image_remote_url
has_attached_file :photo,
:storage => :s3,
:s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
:path => ":class/:id/:style.:extension",
:bucket => "my_bucket",
:styles => {
:icon => "32x32#",
}
def fetch_image
# how should this method look ?
end
end
How should the method "fetch_image" look ? “fetch_image”方法应该怎么样?

I've implemented it successfully on my own site. 我在自己的网站上成功实现了它。
I'm not sure this is still useful for you or not, but in a pull request to paperclip just a few hours ago, I've managed to make this super easy. 我不确定这对你是否仍然有用,但是几小时前我在回形针的拉动请求中,我已经设法让这个变得非常简单。
def set_photo
self.photo = URI.parse(self.image_remote_url)
end
This should do the job now on paperclip (version > 3.1.3) (not 3.1.3 but whatever comes after). 这应该现在在paperclip(版本> 3.1.3)上完成工作(不是3.1.3,而是随后的事情)。
