Send your files to the end user by streaming them from S3

Usage

Installation

Add the gem to your Gemfile and Bundle :

Install initializer file :

rails generate s3streamer:install

Edit the initializer file with your AWS S3 credentials and your bucket name, and restart your server. Note: You can avoid setting your bucket if you pass it directly to the #stream_file method options.

Controller

Now, you can use the #stream_file method in your controllers.

def download
  stream_file("file/key.ext")
end

It can also accept a Paperclip::Attachment object. This method will automatically add "content_type=xxx/xxx" to the Content-Disposition HTTP response header.

def download
  model = Model.find(params[:id])
  stream_file(model.file)
end

There also are options that you can pass :

def download
  stream_file("file/key.ext", {
    name: "File name to be used.pdf",
    content_type: "application/pdf",
    bucket: "your_bucket"
  })
end
