Rails - Jul 2006 - Copying a file from a URL to local machine.

Hello,

In my model, I''d like to be able to copy a remote .jpg file from a URL:

http://<doman.com>/path/picture.jpg

I''d like to copy this to my local machine in my model.  What 
libraries/calls could I make to make this work?

Any help would be appreciated,

Thanks,

Sam.

Sam,

The following is what I do to send a file from MY DOMAIN to the client:

Note:  Substitute your own mime-type.  In this case, p.render is a 
method of PDF::Writer.  If you read a file into an object then it should 
do the same thing (I think).

   send_data p.render, :filename => "my_pdf_filename.pdf", :type
=>
"application/pdf"

OR....you can do this, but I have read some people have concerns because 
it exposes your file location and any other file can subsequently be 
received:

    send_file( path_and_file_name, :type => "application/pdf")

Hope that helps!  I''m not an expert so maybe some of the other more 
senior people will have a better answer.

Do you mean copy the image for a remote server to the server
containing the application or from the application server to a users
local machine?

If it''s the first case you will probably find the net/http and
open-uri libraries useful (they are in the standard lib) in the latter
case see the above post.
