Thanks for a terrific post. This really saved me a ton of effort with an automated rake task pulling products in from an old store into Spree.

@naresh, make sure you have a working “normal” paperclip model before you try to do the “upload via url” additions. Follow the instructions provided in the paperclip readme and you should be good to go.

[...] wasn’t very difficult. There’s some advance stuff you can do with Paperclip, like upload via a URL or upload your files to Amazon’s S3 or define post processing operations on your [...]

i liked your post so much and inspired by this effort i made a small modification in paperclip using this idea and sent a pull request to include this as a feature

you can read about this in my post here

You guys must have been right after all. I was experiencing some problems with URL uploads. I’m not sure why it’s necessary, but I’ve update the article to define the original_filename method on the fly, and now it’s working fine. Thanks for the heads up!

Pierre, this appears to be working fine for me. Please update your Paperclip plugin and let me know if you still have a problem. I believe this is the commit that added original_filename to the StringIO class:

Didier is right.

You should include the original_filename to IO Class from http://almosteffortless.com/2008/10/24/easy-upload-via-url-with-attachment_fu/

Hey Didier – nice to hear from you! It looks like the Paperclip plugin added the original_filename= method in a recent version. I can’t see what commit right now because github is down, but update to the latest version and you should see it in there. Thanks for the heads-up in any case!

Hi Trevor !

A little hello from a (the only one ?) previous French coworker ! Oh yea and happy new year !!!
Go back to serious stuff. Thanks a lot for your article. However, I’ve got one little comment: the StringIO class does not have a “original_filename=” method (example from your download_remote_image method). The solution is to use the code from the attachment_fu version (open the StringIO class and add dynamically the method). But perhaps, I missed something.
I think you should fork paperclip from github and enhance the Upfile class to handle StringIO and more generally remote files. Just an idea (almost effort less ;-).
a+

Florian, I appreciate the suggestion, but I’m getting an undefined method error when I try to use image_url? without defining it myself. I’m guessing that technique you and Tammer mention only works with database-backed attributes.

Florian Dutey — Mon, 15 Dec 2008 10:19:35 +0000

I confirm Tammer’s comment.
You can replace :image_url_provided? by :image_url? wich do exactly the same (!blank?).

Wow. It’s grate to know that uploading images via url is achivable. I haven’t heard of that and Moreover thank you very much for showing how to do it with parerclip. I will surely incorporate this feature in my next rails app. :-)

Thanks for the comment, Tammer. Maybe I’m confused about your suggestion, but I don’t think it will quite work that way. We need to know if the user provided a URL, which we do by checking for a value in image_url. (Rails doesn’t seem to provide me with an image_url? method, perhaps because there’s no db column for the image_url attribute.) If they provided a URL, we try to download the file and verify that the download was successful by checking image_remote_url. Perhaps renaming image_url_provided? to image_url? would be better…?

This looks incredibly useful. One issue, though, is that I don’t think you need the image_url_provided? method. Rails gives you that method via image_remote_url? (with the question mark). In fact, you should be able to use the :allow_blank option for the validates_presence_of call.

Great and useful post.
