Question

I am trying to download the data stored amazon s3 bucket using paperclip and aws-sdk gem. Object is publicly accessible.

I am having a method in my controller where I intend do download the data directly.

def method_where_downloading_happens
  code for finding url from params
  send_file "ModelName.attached_file.url"
end

#Tried both with static and dynamic url.

I am getting following error

NoMethodError: undefined method `send_file for main:Object

However if I use :-

send_file open(ModelName.attached_file.url)

Then a file is downloaded but it’s format is binary i.e. windows can’t identify the file_type.

Please help how do I provide direct download when the person hits the link.

Answer 1

You can try this:

#In your environment.rb require 'open-uri'
require 'open-uri'

#As send_data will work in controller, so in your controller
def index
  data = open(params[:file])
  send_data data, :filename => params[:name], ...
end
