How do I parse a CSV file located in a Amazon S3 bucket

Question

Below is the code I\'m using to parse the CSV from within the app, but I want to parse a file located in a Amazon S3 bucket. It needs to work when pushed to Heroku as well.

Answer 1

You can get the csv file from S3 like this:

require 'csv'
require 'net/http'

CSV.parse(Net::HTTP.get(s3_file_url), headers: true).each do |row|
# code for processing row here
end
