carrierwave, Excon::Errors::MovedPermanently in RegistrationsController#update error - ruby-on-rails

Question

ive been trying to get carrierwave to work with amazon s3. instead of
storage :s3
i have
storage :fog
changing it to storage :s3 gives an immediate error
https://stackoverflow.com/questions/10629827/carrierwave-cant-convert-nil-into-string-typeerror-when-using-s3
so i changed it to storage :fog like the rdoc below says.
http://rubydoc.info/gems/carrierwave/frames
however when i try to upload an image, i get this crazy error. im using the devise gem as well.
my full stack trace is
Excon::Errors::MovedPermanently in RegistrationsController#update
Excon::Errors::MovedPermanently (Expected(200) <=> Actual(301 Moved Permanently)

app/controllers/registrations_controller.rb:30:in `update'
i dont know what that even means.
in my initializers/carrierwave.rb i have..
CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS', # required
:aws_access_key_id => 'somekey', # required
:aws_secret_access_key => 'secretkey', # required
:region => 'eu-west-1' # optional, defaults to 'us-east-1'
}
config.fog_directory = 'bucket.name' # required
#config.fog_host = 'https://s3.amazonaws.com' # optional, defaults to nil
config.fog_public = false # optional, defaults to true
config.fog_attributes = {'Cache-Control'=>'max-age=315576000'} # optional, defaults to {}
end
and my uploader file has
#storage :s3
storage :fog
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
my gem file has
gem 'carrierwave'
gem 'thin'
gem 'fog'
when i boot my server, instead of webrick, it uses thin in development as well.
are my configurations wrong?
help would be much appreciated!
ive been super stuck on this carrierwave/s3 issue

Answer 1

I ran into this the earlier today and it was a problem with the region. Just take it out and let it be set by the default.
CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS', # required
:aws_access_key_id => 'somekey', # required
:aws_secret_access_key => 'secretkey' # required
}
config.fog_directory = 'bucket.name' # required
#config.fog_host = 'https://s3.amazonaws.com' # optional, defaults to nil
config.fog_public = false # optional, defaults to true
config.fog_attributes = {'Cache-Control'=>'max-age=315576000'} # optional, defaults to {}
end

Answer 2

For me worked this configuration
config.fog_directory = 'bucket_name'
config.fog_host = 'https://s3-eu-west-1.amazonaws.com/bucket_name'

Answer 3

I had the same problem.
Following the 3 steps below worked for me.
1.Change the default region when creating a bucket
2.Edit my carrierwave.rb file(as shown below)
initializers/carrierwave.rb:
if Rails.env.production?
CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS',
:aws_access_key_id => ENV['S3_ACCESS_KEY'],
:aws_secret_access_key => ENV['S3_SECRET_KEY'],
:region => ENV['S3_REGION']
}
config.fog_directory = ENV['S3_BUCKET']
end
end
3.Configure heroku in the command line as in: heroku config:set S3_REGION='your region'

Answer 4

Just like #Jason Bynum said, do not specify the region and let it default.
If you still fail, don't worry, At this time, heroku will give hint to you like your region specified is wrong and should be xxx
And you know how to fill the region right now :)
The followings work for me:
CarrierWave.configure do |config|
config.fog_credentials = {
provider: 'AWS', # required
aws_access_key_id: ENV['S3_KEY'], # required
aws_secret_access_key: ENV['S3_SECRET'], # required
region: 'ap-southeast-1', # optional, defaults to 'us-east-1'
}
config.fog_directory = 'your_bucket_name' # required
config.fog_public = false # optional, defaults to true
config.fog_attributes = { 'Cache-Control' => "max-age=#{365.day.to_i}" } # optional, defaults to {}
end
Gemfile:
gem 'carrierwave', '0.10.0'
gem 'fog', '1.36.0'
