Paperclip Walkthrough

Given we have a Model Track with an associated Paperclip attachment called 'audio'

First lets create an empty template spreadsheet

bundle exec thor datashift:generate:excel -m Track -r db/seed/track_covers.xls

Remove id, created_at etc leave just title and audio_file

Now we get a listing of the MP3s we want to bulk upload

find /media/MusicMaking/MASTERS/ -name *.mp3

Copy and paste that into the audio_file column

Grab all the titles ... the exact specifics of the cuts will vary depending on the format you use to id your tracks

Mine just happens to be number.title_bpm_date so this grabs my titles

find /media/sf_Dropbox/MusicMaking/MASTERS/ -name *.mp3 | cut -d '.' -f 2 | cut -d '_' -f 1
