Rails 4，Heroku上的Paperclip无法识别损坏的图像

Question

having trouble solving problem with pictures on my project.

Summary: Rilas 4 hosted on Heroku using Paerclip with S3

Problem starts with having to use previously used custom uploading logic with S3. picture url looks something like this /profile_picture/:style_:image_hash . It works fine with images that are there but with images that are not present paperclip still trying to access image that is not there and the actual link look something like this: http://s3.amazonaws.com/project/profile_pictures/100h_ .

 has_attached_file :picture,
                styles:          { :'53h' => '', :'100h' => '' },
                convert_options: {
                    :'100h' => '-gravity center -thumbnail 165x165^ -extent 165x165',
                    :'53h'  => '-gravity center -thumbnail 45x45^ -extent 45x45'
                },
                path:            'profile_pictures/:style_:filename',
                default_url:     '/images/default-pp-large.jpg'

I am guessing that might be because of style inside the actual filename, but i am not sure, eather way defauly_url is not working and images all are broken, excluding the ones that are actually there.

Can you help please?

Answer 1

In the end i made a monkey pach to paperclip gem. Added this lines to config/initializers/paperclip.rb

module Paperclip
  class Attachment
    alias_method :original_url, :url

    def url(style_name = default_style, options = {})
      if @instance.public_send("#{@name.to_s}_file_name").blank?
        'default-pp-large.jpg'
      else
        original_url(style_name, options)
      end
    end
  end
end

Answer 2

i'm wondring how is the ID is not present in the path for the picture, as in this case if 2 differents Pictures with same name it will retrieve the first match as i think, path should be something like:

path: 'profile_pictures/:id_:style_:filename'
# OR
path: 'profile_pictures/:id/:style_:filename'

not sure if that should be totally solving the problem but that is a part of it.
