Rails form field to ask for directory to download to

Rails
1

Hi all,

I need a way to ask a user to supply a directory on their computer (i.e.
client) to which to download a series of files. So in other words, the
user is asked:

Please indicate directory to download to: …

And they click or something and get a chooser with which they can point
to a directory on their computer. (Not a file, a directory, that may not
yet exist, or that may be empty.)

There must be a gem or something out there to help do this in a cross
platform way, can anyone point the way?

Thanks a lot!

Yes but as I said in my question, I want the user to designate a
directory to receive file(s), not a specific file name to download into.
I am guessing that the solution will involve some javascript/ajax/or
something, and I am also guessing that the browser inherently doesn’t
have a feature to raise a chooser dialog box to choose a destination
folder (not filename.)

(Note: if I want to receive files in a directory called ~/mydownloads
then I need a dialog box that lets me navigate my directory structure
locally, but choose a directory not a file. The normal file open dialog
box displayed by a browser makes me choose an existing file, as far as I
understand…)

I think this is totally browser, user-specified browser preferences,
and OS dependent, so I wouldn’t count on a server-side solution.

But good luck :slight_smile:
