images uploaded to aws, but can't be viewed in the view

问题

I have just integrated AWS with my rails/heroku app and I am using paperclip. I am able to upload files (photo's) and see them in AWS, however they are not showing up in the view. I am not getting any errors, and have not found a working solution in other posts.

It seems I am able to view the image in a browser, and that permissions are set to public:

I suspect that I may have my region wrong, in the url of my aws dashboard the region says region=us-west-2 yet googling and reading through other forums and posts on SO leads me to believe that if I am in the US my region should be set to us-east-1 - currently I have it set to the latter. Not sure if this is the problem.

Here is a link to the image on AWS:https://s3.amazonaws.com/giving-tree-images/avatars/1/medium/02108_navajoland_1440x900.jpg

here is the code pertaining to aws/paperclip in my model:

:storage => :s3,
# :s3_host_name => "s3-us-east-1.amazonaws.com",
:s3_credentials => {
  :bucket => ENV['S3_BUCKET_NAME'],
  :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
  :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
},

:path => ":rails_root/public/system/:attachment/:id/:style/:filename", 
:default_url => "default_img.png"

and I am displaying in the view like this:

<%= image_tag @user.avatar.url(:medium) %>

I would love it if someone could point me in the right direction... Any additional info needed, please let me know!

I also faced the same issue, so this is how I solved it:

1. Create a new initializer file i.e. config/initializers/paperclip.rb
2. Add following in this file Paperclip::Attachment.default_options[:url] = ':s3_domain_url' Paperclip::Attachment.default_options[:s3_host_name] = 's3-us-west-2.amazonaws.com'

To get details about your region, go to aws

Amazon Web Service - Check your host name

Note : Replace s3-us-west-2.amazonaws.com with your own host name

Have you enable the read permission to everyone? It gave me access-denied error when accessed to the link.
