Copying a file from a URL to local machine

Rails
1

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.
