Comfy needs downgraded aws-sdk gem to work

[Momus]

This is a result of an open issue with Paperclip, that should be fixed any day now but it gave me much trouble, so I thought I would at least document it here.

Symptoms:

File uploads to AWS S3 don't work. You observe a progress bar, but soon it turns red with the message: NameError in Comfy::Admin::Cms::FilesController#create
The server spits out the following:

   Comfy::Cms::File Exists   (0.2ms)  begin transaction
Command :: PATH=/usr/local/bin:$PATH; file -b --mime '/tmp/8b43e47c717a305e664b5c2ee6488f7a20150710-4457-11dz6dk.jpg'
  Comfy::Cms::File Exists (0.2ms)  SELECT  1 AS one FROM "comfy_cms_files" WHERE ("comfy_cms_files"."file_file_name" = 'TestFile.jpg' AND "comfy_cms_files"."site_id" = 1 AND "comfy_cms_files"."block_id" IS NULL) LIMIT 1

(0.1ms)  SELECT MAX("comfy_cms_files"."position") FROM "comfy_cms_files"
  SQL (0.5ms)  INSERT INTO "comfy_cms_files" ("file_file_name", "file_content_type", "file_file_size", "site_id", "label", "created_at", "updated_at", "position") VALUES (?, ?, ?, ?, ?, ?, ?, ?)  [["file_file_name", "TestFile.jpg"], ["file_content_type", "image/jpeg"], ["file_file_size", 32758], ["site_id", 1], ["label", "197810 Test File"], ["created_at", "2015-07-11 00:45:49.049994"], ["updated_at", "2015-07-11 00:45:49.049994"], ["position", 2]]

Fix:

In your Gemfile:
gem "aws-sdk" , '<2.0'

It's up to Paperclip: there is a pull request with the fix: thoughtbot/paperclip#1730
AWS v2 support seems to be their most requested feature, so I'm sure it's high in their queue. For now, using the v1 branch of aws-sdk (1.64.0) worked for me.

Thoughtbot has released version 4.3 of Paperclip 18 hours ago. Haven't tested it yet, will close issue if it works.

Version 4.3 of paperclip does not include aws-sdk v2 support. I'm testing current master and it seems to work.

Paperclip now supports aws-sdk 2x. https://github.com/thoughtbot/paperclip/blob/master/UPGRADING

I was getting an error in Comfy (listing files in admin view) recently after upgrading some gems, I didn't research why but I'm assuming it was due to Paperclip being upgraded from 4.3.7 to 5.0.0. Upgrading to aws-sdk 2 latest and setting s3_region in the comfy paperclip initialiser fixed it.

So I think this issue should be closed now.
