Rails 3 - Amazon S3 Paperclip EU Problem - ruby-on-rails-3

Question

I'm using:
Paperclip 2.3.16
Rails 3.0.9
Ruby 1.9.2
AWS - S3 0.6.2
I'm trying to use paperclip the upload to the EU (Ireland) based bucket. I have the following in my model:
has_attached_file :image, :styles => { :grid => '90x128#', :list => '140x200#', :original => '400x548'},
:storage => :s3,
:s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
:url => 'flyers/:id/:style/:basename.:extension',
:path => 'flyers/:id/:style/:basename.:extension',
:bucket => 'fsight'
In my environment.rb I have set the write to use the AWS/s3 Default Host to the relevant EU one by using:
require "aws/s3"
AWS::S3::DEFAULT_HOST.replace "s3-eu-west-1.amazonaws.com"
This works fine, and it allows me to upload the images, and I can verify the image upload / delete using the AWS Management consoler.
However, I have a problem when trying to display the images on my site. The images do not load and I have identified the cause, as the URL generated uses the old default host. Eg:
What it should be:
https://s3-eu-west-1.amazonaws.com/fsight/flyers/50/full/4759543368588654950.jpg
What it actually is: http://s3.amazonaws.com/fsight/flyers/50/full/4759543368588654950.jpg?1314801178
As you can see, it uses the old default host.
I tried placing:
Paperclip.interpolates(:s3_eu_url) do |att, style|
"#{att.s3_protocol}://s3-eu-west-1.amazonaws.com/#{att.bucket_name}/#{att.path(style)}"
end
But then started receiving the following error:
wrong number of arguments (0 for 1)
Extracted source (around line #9):
<img src= <%= #event.image.url(:original) %>
I know Paperclip has some issues with using EU Buckets, but could anybody help me with this?

Answer 1

You don't need to work around the EU Problem anymore.
The default aws-s3 storage backend in paperclip was replaced by the AWS SDK for Ruby, that is also the amazon recommended way when working with AWS.
Just insert
gem 'aws-sdk'
into your Gemfile and run bundle install.
If you want something like https://s3-eu-west-1.amazonaws.com/some_path_goes_here, try to configure your model's has_attached_file with the following options
:storage => :s3,
:s3_credentials => "#{Rails.root}/config/s3.yml",
:s3_permissions => :private,
:s3_protocol => 'https',
:s3_host_name => 's3-eu-west-1.amazonaws.com',
:path => ":filename"
If you don't want to use https you can remove the :s3_protocol and if you want to change the region, option :s3_host_name is the right way to go. You can also put this into a configuration file.
Hope this helps.

Answer 2

Did you try this workaround?
Paperclip et les European S3 buckets
Or even this one?
Paperclip, S3, and European Buckets

Answer 3

I added
Paperclip::Attachment.default_options[:s3_host_name] = 's3-eu-west-1.amazonaws.com'
to paperclip.rb in the initializers folder and it works fine for me.

Answer 4

Same problem here, just solved passing the following option to has_attached_file:
:url => ':s3_domain_url'
For more info see here http://rubydoc.info/gems/paperclip/Paperclip/Storage/S3 :
Normally, this won't matter in the slightest and you can leave the default (which is path-style, or :s3_path_url). But in some cases paths don't work and you need to use the domain-style (:s3_domain_url).
