Carrierwave files not deleting from S3 - ruby-on-rails

Question

I'm using the carrierwave and carrierwave-aws gems to upload to S3 from a Rails application. I can upload files without any issue, but I can't remove them from S3.
My ActiveRecord model is called Episode and its video property is set by my CarrierWave::Uploader::Base uploader (which includes CarrierWave::Video).
Here are the steps I've followed:
Create an episode
Upload a video, verify it exists on S3 (this works!)
Call episode.remove_video!; episode.save! from the console
At this point, the video still exists on S3, despite receiving no error message
I've also tried:
episode.video.remove!
episode.save!
Which produces this output, but doesn't delete the file from S3:
[180] pry(main)> episode.video.remove!
=> [:remove_versions!]
I've also tried:
episode.destroy!
which should call the ActiveRecord callback added by Carrierwave, but doesn't. I added my own before_destroy method (destroy_assets below), but this also doesn't work.
Here is my setup:
carrierwave.rb
CarrierWave.configure do |config|
config.storage = :aws
config.aws_bucket = 'BUCKET_NAME'
config.aws_acl = 'public-read'
config.aws_authenticated_url_expiration = 60 * 60 * 24 * 7
config.aws_attributes = {
expires: 2.week.from_now.httpdate,
cache_control: 'max-age=604800'
}
config.aws_credentials = {
access_key_id: ENV['aws_access_key'],
secret_access_key: ENV['aws_secret'],
region: 'us-east-1'
}
config.remove_previously_stored_files_after_update = true
end
video_uploader.rb
class VideoUploader < CarrierWave::Uploader::Base
include CarrierWave::Video
storage :was
def store_dir
"uploads/videos/#{model.id}"
end
end
episode.rb
class Episode < ActiveRecord::Base
mount_uploader :video, VideoUploader
before_destroy :destroy_assets
def destroy_assets
self.video.remove! if self.video
self.save!
end
end
The AWS credentials I'm using are for an IAM user with the AmazonS3FullAccess policy, if that makes any difference here.

Answer 1

I would update your store_dir to be:
"uploads/videos/#{mounted_as}/#{model.id}"
So that carrierwave, while utilizing the mounting system, removes the file, it knows where to find it when it calls the full name method internally!
