.pull_tempfile(original_filename:, url:) ⇒ Object

Creates Temporary file

file = PullTempfile.pull_tempfile(original_filename: "image asset.jpg", url: 'http://..../uaoeuoeueoauoueao' )
# ...do stuff
file.unlink

Temporary files have suffix so your file “image asset.jpg” will be saved as “/tmp/image asset20160317-18066-gw1q0.jpg”. This is because Tempfile lib is ensuring you won’t override files

Remmember to ‘file.unlink` or PullTempfile.transaction that does that automatically
