I'm using carrierwave_direct gem for uploading files directly to the aws but as it is mentioned on the documentation that only one file can be uploaded at a time, can some one please suggest me a way to upload multiple files at a time.

I want to allow my user to download a bundle of files that are stored on s3 using the zipline gem. The files are already hosted on an s3 server but they aren't there as part of a paperclip or carrierwave attachment in my app. Will I need to create some records in my database to sort of trick zipline into thinking they are paperclip attachments, or is there a way I can send the zip file without bothering with an attachment gem? At the moment, trying to download the files with zipline doesn't throw an error message at all. It just seems to skip right over and nothing downloads.
See the part of the zipline README where an enumerator gets used to include remote files into the ZIP. It uses absolute URLs, to generate those from your S3 objects you will need to use presigned URLs (which Zipline is going to pass on to Curb):
Aws::S3::Bucket.new(your_bucket_name).object(your_key).presigned_url(:get)
I am creating a Rails app which should allow users to upload any type of audio file format. I am currently using Carrierwave gem to accomplish this, however CarrierWave will not allow uploads of certain file formats such as .band (GarageBand default format).
Is there a way to accomplish this?
Well, .band is actually a folder containing multiple files. So, yes, carrierwave does not allow uploads of folders. The folder must be converted into a .zip file.
In rails 4.0.2, I am using s3_direct_upload gem to upload files directly to s3, after that I want to store the files & convert it to html, also I want to store some dependency files like converted .html / .txt files back to s3. But I am not able to get the files from s3 & also it is not saving to the database.
I have referred this from http://blog.littleblimp.com/post/53942611764/direct-uploads-to-s3-with-rails-paperclip-and.
How can I overcome this problem? awaiting for the solution.
I have a rake task that creates a CSV file. Right now I am storing this file into my /tmp folder (I am using Heroku). This CSV file is not associated with any model, it's just some data I pull from several APIs, combined with some data from my models.
I would like to download this file from Heroku, but this seems not possible. So, my question is: Which gem am I trying to look for in order to upload that file to Amazon S3? I have seen gems like Paperclip, but that seems to be associated with a model, and that is not my case. I just want to upload that CSV file that I will have in /tmp, into my Amazon S3 bucket.
Thanks
You can use aws-s3 gem
S3Object.store('filename_in_s3.txt', open("source_file.tmp"), 'bucket_name')
You should define the exact path of your tmp file, for example:
open("#{Rails.root}/tmp/source_file.tmp")
CarrierWave can directly interface your Ruby application with S3 directly via the Fog library. Rather than operating on the model level, CarrierWave utilizes a Uploader class where you can cull from across your APIs and datasources, which is precisely what you're trying to accomplish.
I want to create a simple form for users to upload a file, which will be stored in a database. I also want to display all the submitted files in the database with their name and a link to download the file. Schematically, what's the best way to do this in Rails/how should I store the file in table (which fields should my table have? etc). Thanks!
i would use paperclip gem with the upload to s3 instead of file system

checkout the README, most of the examples are for an image, but works with non-image files as well
use paperclip to upload file, you can store images/file in your database as well as in s3 (AWS)
See below link how to use paperclip in rails with example
