Streaming not working

[mattfordham]

Here there. I can't seem to get streaming working in my Rails app on Heroku with Unicorn. I also tested locally with Foreman with no luck. I am using the same view code as is in the test app for this gem. The file download never initiates... it just spins while it cranks through the loop. I know this isn't much to go on, but is there anything I could be missing?

Controller:

  @streaming = true
  @filename = 'report.csv'
   respond_to do |format|
     format.csv
end

View:

10_000_000.times do |i|
   csv << ["this","is","a","scale","test",i.to_s]
end

Procfile:
web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb

Unicorn.rb

timeout 30         # restarts workers that hang for 30 seconds```

Here's an update. I noticed that I have to use gem 'csv_streamer' not csv_builder. After switching that, I get the following when trying to start the server:

ERROR -- : uninitialized constant ActionView::Template::Handler (NameError) 11:49:54 web.1 | /Users/matt/.rvm/gems/ruby-1.9.2-p180/gems/csv_streamer-0.0.3/lib/csv_streamer/template_handler.rb:81:in module:CsvBuilder'

Any ideas? Thanks!

OK, one more update :)

I cloned your test project for this gem, and it worked. I updated the Rails version on that to 3.2.2 and produced the same error I was getting before.
