Paperclip: Upload from Url with Extension

Paperclip: upload from url with extension

Good timing. I just sent a pull request that was patched in a few hours ago (Jul 20 2012) which should make your life real easy.

self.asset = URI.parse("http://s3.amazonaws.com/blah/blah/blah.jpg")

This will download your jpeg image, ensure that the filename is blah.jpg and the content type is 'image/jpg'

Paperclip version > 3.1.3 (you'll need to link it to github repo until it gets released).

UPDATE: confirmed working with paperclip version >= 3.1.4

Save image from URL by paperclip

Here is a simple way:

require "open-uri"

class User < ActiveRecord::Base
  has_attached_file :picture

  def picture_from_url(url)
    self.picture = open(url)
  end
end

Then simply :

user.picture_from_url "http://www.google.com/images/logos/ps_logo2.png"

Paperclip add image from URL in has_many association

Here is a great gist (that I did not write). It should get you there: https://gist.github.com/jgv/1502777

require 'open-uri'

class Photo < ActiveRecord::Base

  has_attached_file :image # etc...

  before_validation :download_remote_image, :if => :image_url_provided?

  validates_presence_of :image_remote_url, :if => :image_url_provided?, :message => 'is invalid or inaccessible'

  private

  def image_url_provided?
    !self.image_url.blank?
  end

  def download_remote_image
    io = open(URI.parse(image_url))
    self.original_filename = io.base_uri.path.split('/').last
    self.image = io
    self.image_remote_url = image_url
  rescue # catch url errors with validations instead of exceptions (Errno::ENOENT, OpenURI::HTTPError, etc...)
  end

end

In the future, it's usually best to post the code with your attempt to solve the problem.

Rails paperclip image URL uploading not working

I was in the middle of writing a pretty through response, and then I found someone already wrote the same thing!!

Here you go: http://trevorturk.com/2008/12/11/easy-upload-via-url-with-paperclip/

This should be exactly what you are looking for. If you stumble, let me know.

Good luck

How to use original image url in paperclip

<%= photo.attachment.url(:original) %>

That will give you the path to the original file, you can also get the other styles if needed:

<%= photo.attachment.url(:thumbnail) %>
<%= photo.attachment.url(:profile_gallery) %>
