【问题描述】:
我有一份产品清单。对于每个产品,我都有一个 image_url,我想将其上传到我的 AWS S3 账户并与之关联。
我可以通过表单手动完成,但是对于大约 1500 种产品,我无法一一完成。
我的回形针配置如下所示:
config.paperclip_defaults = {
:url => 'xxxx',
:path => '/:class/:attachment/:id_partition/:style/:filename',
:command_path => "/usr/bin/convert",
:storage => :s3,
:s3_credentials => {
:bucket => "xxx",
:access_key_id => "XXX",
:secret_access_key => "XXXX"
}
}
这是我用来手动上传图片的代码
class Product < ActiveRecord::Base
# This method associates the attribute ":image" with a file attachment
has_attached_file :image, styles: {
thumb: '100x100>',
square: '200x200#',
medium: '300x300>'
}
# Validate the attached image is image/jpg, image/png, etc
validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/
end
一切顺利,我可以在日志末尾看到:
[paperclip] saving /products/images/000/001/361/original/xxx.jpg
[AWS S3 200 1.107584 0 retries] put_object(:acl=>:public_read,:bucket_name=>"xxx",:content_length=>47766,:content_type=>"image/jpeg",:data=>Paperclip::UploadedFileAdapter: xxx.jpg,:key=>"products/images/000/001/361/original/xxx.jpg")

但现在我想自动执行此任务(在为数据库播种时)。我添加了open-uri 以从他们的 URL 中检索图像。
require 'open-uri'
class Product < ActiveRecord::Base
# This method associates the attribute ":image" with a file attachment
has_attached_file :image, styles: {
thumb: '100x100>',
square: '200x200#',
medium: '300x300>'
}
# Validate the attached image is image/jpg, image/png, etc
validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/
def image_from_url(url)
self.image = URI.escape(url)
end
end
我基本上做的是用类似的东西创建一个新产品:
Product.create! :name => "Test!!!"
然后尝试添加图像:
Product.last.image_from_url "MY_URL"
我对此没有任何错误,但它不起作用。我可以在日志中看到每种格式(拇指、正方形、中等)的转换,但它不像以前那样推送到 AWS。
