using attachment_fu to store mp3

Hi,

I am trying to store mp3 files using the attachment_fu and I have
managed to store it on the file system and the database as a blob. The
problem is I dont know if saving it in the public folder of the file
system is safe and when I store it as an longblob in the database how do
i send it back to the user as something that can be downloaded.

I apologize if this sounds too silly as I am a newbie and trying to
build an app which handles large amounts of mp3 files. I am also worried
about security of storing the music files on the public folder.

I would appreciate any help on this .

Thank you

You probably do not want to store the files in public. Store them
somewhere else if you need to protect them with passwords.
You can easily upload them to Amazon's S3 with attachment_fu, just be
sure to set :s3_access to an appropriate value
And you can use send_data with :disposition => 'inline' to send the
data to the user. See http://api.rubyonrails.org/classes/ActionController/Streaming.html

Thank you for the response. I read on a few forums that storing it on
the public file is better because it reduces databases access time which
may eventually slow done the entire application. As I would be working
with a lot of mp3 files is there anyway I can store them in folder that
can be protected because Mysql does not handle the blob format very well
and I am unable to get it retrieve it with the same quality.

Can mp3s be stored in mysql in any other way like binary format and
retrieved without loss of quality.

Thank you again.

Slow down and think. You can store files in the local filesystem in
places other than your Rails apps /public directory. hitch linked you
to http://api.rubyonrails.org/classes/ActionController/Streaming.html;
send_file is a good place to start. (Though in practice this just
tends to be good at tieing up a specific Rails instance during the
file sending process and you'll eventually use something like
mod_xsendfile, but take one thing at a time!)
