Nokogiri+Paperclip = XML parse with img from url - ruby-on-rails

Question

I need to parse some params to my DB and image from URL.
I use paperclip for image.
In Rails console I can add image to new post by this code:
image = Image.new
image.image_from_url "http://yug-avto.ru/files/image/tradein/hyundai/877_VOLKSWAGEN_FAETON_2011_2_1366379491.jpg"
image.watermark = true
image.save!
in my Image model I have
require "open-uri"
.......
def image_from_url(img_url)
self.image = open(img_url)
end
And all work done. But when I use Nokogiri, this code don't work.
rake aborted!
No such file or directory -
http://yug-avto.ru/files/image/tradein/peugeot/1027_Peugeot_308_2011_2_1370850441.jpg
My rake task for Nokogiri parse:
doc.xpath("//item").each do |ad|
img = ad.at("image").text
img1 = Image.new
img1.image = open("#{img}")
img1.watermark = true
img1.save!
end
In rake task for Nokogiri, I have require 'nokogiri' and require 'open-uri'.
How to be?:))))

Answer 1

This is a code snippet from my parser... I guess where you went wrong is using open(url) instead of parse(url).
picture = Picture.new(
realty_id: realty.id,
position: position,
hashcode: realty.hashcode
)
# picture.image = URI.parse(url), edit: added open() as this worked for Savroff
picture.image = open(URI.parse(url))
picture.save!
Additionally it would be a good idea to check if the image really exists
picture_array.each do |url|
# checks if the Link works
res = Net::HTTP.get_response(URI.parse(url))
# if so, it will add the Picture Link to the verified Array
if res.code.to_i >= 200 && res.code.to_i < 400 #good codes will be betweem 200 - 399
verified_array << url
end
end

Thanks TheChamp, you led me to the right thoughts.
First need to parse URL and after that open.
image = Image.new
ad_image_url = URI.parse("#{img}")
image.image = open(ad_image_url)
image.watermark = true
image.save!
