Ok that makes sense. Thanks Brian.
On the same topic...
How would I create a temp file with .png extension in the end.
tmp = Tempfile.new([ 'thumb', 'png' ].compact.join("."))
Whenever it creates a temp file, it creates it as such:
thumb.png20101111-989-1pt72my, instead of
thumb20101111-989-1pt72my.png
If I try to save this via Active Record, with
@video.attachment_thumbnail =
File.open("#{File.expand_path(tmp.path)}"),
It will save the file in the file system without the extension, which
makes it impossible to read on the browser, unless I explicitly set
the extension.
