Rails Engine not uploading to s3 with Carrierwave - ruby-on-rails

Question

I am creating a rails plugin with rails new plugin my_plugin --mountable
This was quite some work to figure out but it is supposed to upload files to S3 with carrierwave, but it says ok but nothing is uploaded
Carrierwave is used to generate an uploader with rails g uploader photo
the file looks like this
# my_engine/app/uploaders/my_engine/photo_uploader.rb
# encoding: utf-8
module my_engine
class PhotoUploader < CarrierWave::Uploader::Base
# Choose what kind of storage to use for this uploader:
storage :file
# storage :fog
# Override the directory where uploaded files will be stored.
# This is a sensible default for uploaders that are meant to be mounted:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
end
end
the model had an mount :photo, PhotoUploader
module PdfGeneratorEngine
class Assemble < ActiveRecord::Base
attr_accessible :color, :photo, :qr_code_url, :text
mount_uploader :photo, PhotoUploader
end
end
my CarrierWave config file is this
CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS',
:aws_access_key_id => 'MY_ACCES_KEY',
:aws_secret_access_key => 'MY_SECRET_KEY',
:provider => 'AWS',
:region => 'eu-west-1'
}
config.fog_directory = 'my.bucket.com'
config.fog_host = 'https://s3-eu-west-1.amazonaws.com/my.bucket.com'
config.storage = :fog
config.s3_use_ssl = true
config.fog_public = true
end
So first of all it starts screaming at fog_host, it is okay if it is asset_host
Next it's problem lies within s3_use_ssl, while it is an merged issue on CarrierWave's github. But the host is already defined as https:// so I don't see why that line is necessary.
After that it says 'Okay it's done' and when I try to check (with a deamon) for the file, there's nothing there.
What did I miss? Or is there something of an issue with CarrierWave and Rails mountable engines?

Answer 1

In your photo_uploader.rb
comment storage:file and uncomment storage:fog
# storage :file
storage :fog
--
Look at your fog.rb, Its inconsistent with what is given here
carrierwave#using-amazon-s3
CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS', # required
:aws_access_key_id => 'xxx', # required
:aws_secret_access_key => 'yyy', # required
:region => 'eu-west-1' # optional, defaults to 'us-east-1'
:hosts => 's3.example.com' # optional, defaults to nil
:endpoint => 'https://s3.example.com:8080' # optional, defaults to nil
}
config.fog_directory = 'name_of_directory' # required
config.fog_public = false # optional, defaults to true
config.fog_attributes = {'Cache-Control'=>'max-age=315576000'} # optional, defaults to {}
end

Okay So there is a bit of a problem with CarrierWave.
I have quickly setup RightAws and now it uploads to S3 and I can find it from my deamon.
in my uploader I added
#s3 = RightAws::S3Interface.new('MY KEY', 'MY SECRET KEY')
#s3.put('my.bucket.com', assemble.photo.identifier ,params[:assemble][:photo])
Thanks for your help Nishant, CarrierWave would be a lot slicker and nicer but it currently does not work. There has been an issue for this in their github regarding use in Rails engines.
