回形针4.0不保存图像和名称

Question

I have a product model

#(product.rb):
def get_image_from_link 
unless url.blank?
encoded_url  = URI.encode(url)
self.image  = URI.parse(url)
end

With the following validations:

validates_attachment_content_type :image, content_type: /\Aimage/
validates_attachment_file_name :image, matches: [/png\Z/, /jpe?g\Z/]

I am parsing some thousands of URLs to Paperclip 4.0. Paperclip is not saving the image and the name in the database for some of the URLs.

Problem is, I cannot see any error and I cannot see the answer from the problematic urls. Instead of writing the SQL back it states ROLLBACK. Any idea?

This URL would work: http://i.stylepit.com/common/225162/33/225162_1_2_33.jpg This URL would not work: http://lsco.scene7.com/is/image/lsco/Levi/clothing/658190078-front-grid.jpg

Here the rails log:

Answer 1

Problem was params. Not all fields in the database were filled. Therefore no file downloaded and saved by paperclip.

Thanks for your help!
