uninitialized constant AWS::S3::Base via AWS-SDK

Question

This is an issue I'm having with the fact that after I upgraded to AWS-SDK (instead of aws-s3) with the newer version(s) of paperclip I can no longer call AWS::S3::Base.establish_connection! at all.

Where ever in my code I call

AWS::S3::Base.establish_connection!(:access_key_id => '****', :secret_access_key => '***')

I get this error...

NameError (uninitialized constant AWS::S3::Base):
    app/models/asset.rb:28:in `move_upload_from_temp_to_final_resting_place'

Answer 1

Yeah,aws-sdk doesn't have AWS::S3::Base . I think this is the closest equivalent:

s3 = AWS::S3.new(:access_key_id => '****', :secret_access_key => '***')

Answer 2

As this was the first page that popped up for me on my google search to solve this issue I will comment on how I managed to solve it. Under the AWS SDK 2.0.47

require 'rubygems'
require 'aws/s3'

include AWS::S3

AWS::S3::Base.establish_connection!(
   :access_key_id => '',
   :secret_access_key => ''
)

I was simply missing the include AWS::S3. And I suspect many people are running into this issue as I have yet to see a straight foward answer.

Answer 3

I tried Konstantino solution but, unfortunately, it didn't work for me. using include AWS::S3 threw the following exception.

TypeError: wrong argument type Class (expected Module)

This is how I solved the same issue

AWS.send(:remove_const, :S3) if AWS::S3.class == Class
require Gem::Specification.find_by_name("aws-s3").gem_dir + "/lib/aws/s3.rb"

as I was using aws-s3 's modules and methods in another method that was initiated using delayed_job , this patch didn't create issue in my case. But this can create issues in another use case as aws-sdk 's class is now replaced with aws-s3 's module.
