Is it possible to get the absolute URI for a Paperclip attachment? Right now, the problem is that the production environment is deployed in a sub-URI (on Passenger: RackBaseURI), but <paperclip attachment>.url returns the Rails-app relative URI (/system/images/...). Is there a way to get the absolute URI for Paperclip attachments?

我使用的是 Paperclip v2.7 和 Rails 3.2.8.

推荐答案

try

URI.join(request.url, @model.attachment_name.url)

或

URI(request.url) + @model.attachment_name.url

使用 S3 或绝对网址是安全的.

It's safe if you use S3 or absolute url.
