Rails::StreamFile

Add this line to your application's Gemfile:

gem 'rails_stream_file', git: 'https://github.com/berfarah/rails_stream_file', require: "rails/stream_file"

And then execute:

$ bundle

Adds stream_file method to rails which takes an enumerator to output a binary file. Example usage below:

require "csv"
class EnumerableObject
  def each(&block)
    block.call %w(My Headers Go Here).to_csv
    block.call [1, 2, 3, 4].to_csv
    [
      [123, 123, 123, 123],
      [123, 123, 123, 123]
    ].each { |e| block.call(e.to_csv) }
  end
end

class MyController < ActionController::Base
  def show
    stream_file EnumerableObject.new, filename: "example.csv", mimetype: "text/csv"
  end
end
