sanjayginde / Attachment_from_remote_url_with_Paperclip.md
Last active May 17, 2016 14:25 — forked from jgv/gist:1502777
Support setting a Paperclip attachment from a remote URL with a generic mixin for Rails

See also: http://almosteffortless.com/2008/12/11/easy-upload-via-url-with-paperclip/

Forked from: https://gist.github.com/1502777

The goal was a more generic solution to the one in gist this is forked from. It does not require the addition of any more db columns, as I choose not to store the remote URL.

Currently missing, is validation of the remote URL and error handling. Probably makes sense to just work with ActiveRecord::Errors

Currently, the file upload takes precedence over the the remote url, if a user supplies both. I'm thinking that should probably be an option flag on can_attach_remote_url.
