ruby on rails - Paperclip uploads on Heroku using S3 -

i'm sorry rehash old gripe i'm @ wits end , not sure go next. using paperclip on heroku , have s3 uploads configured. able things working in local development environment once it's running on heroku run error:

aws::s3::errors::permanentredirect (the bucket attempting access must addressed using specified endpoint. please send future requests endpoint. 

i've googled error , read through heroku documentation , believe have set correctly. thought problems stemmed having bucket in s3-us-west-1.amazonaws.com region, i'm not convinced anymore.

here relevant parts of heroku config:

aws_region:                      us-west-1 s3_bucket_name:                  my-super-awesomely-amazing-bucket 

from config/environments/production.rb file:

  config.paperclip_defaults = {   :storage => :s3,   :s3_credentials => {       :bucket => env['s3_bucket_name'],       :access_key_id => env['aws_access_key_id'],       :secret_access_key => env['aws_secret_access_key']     }    } 

my paperclip.rb initialize file:

if rails.env.production?    paperclip::attachment.default_options[:url] = ':s3_domain_url'   paperclip::attachment.default_options[:path] = '/:class/:attachment/:id_partition/:style/:filename'   paperclip::attachment.default_options[:s3_host_name] = 's3-us-west-1.amazonaws.com' end 

and paperclip config relevant model:

has_attached_file :document, :styles => { }, :default_url => "/image_styles/:style/missing.png" 

so...what doing wrong here? @ point i'm sure i've missed obvious i'm stumped on go here. feel i've assiduously configured , yet permanentredirect error keeps coming up.

bucket

this might not direct solution, we've found have include bucket option outside of s3_credentials block:

#config/environments/production.rb config.paperclip_defaults = {     storage: :s3,     s3_host_name: 's3-eu-west-1.amazonaws.com',     s3_credentials: {       access_key_id: env['aws_access_key_id'],       secret_access_key: env['aws_secret_access_key']     },     bucket: env['s3_bucket_name'] } 

this working 100% on heroku, whether wil work (as bucket in different region) different matter

if need more help, ask comment , i'll gladly give ideas
