How to link to captured audio file?

Hi I’m just getting into Rails and have come across a problem I can’t find a solution for.

Basically, answers is a sub resource of questions and you can record an answer using HTML5’s getUserMedia.

The recording is posting fine in the create action, but how can I get it again for the show action?

The answer controller includes:

def save_file

audio = params[:audio]

save_path = Rails.root.join(“public/#{audio.original_filename}”)

audio.rewind, ‘wb’) do |f|




The show view includes:

Play answer

Could anyone please hint at what I need to insert into ???
