I'm developing a simple webapp in web2py and I want to create a link that
let's the user download a file. Like this:
<a href="{{=URL('download',args = FILE)}}" download>
However, I want to do this without having to pass the FILE to the user in
the page handler. I want to retrieve an ID from the server asynchronously
that will correspond to the file I want to download an then pass it to a
custom download function like this:
<a href="{{=URL('custom_download',args = FILEID)}}" download>
This way, I will be able to upload files to the server asynchronously, (I
already figured out how to do that) and the download link on the page for
that file will work right away without having to reload the page.
So, on the server side, I would do something like this:
def custom_download():
download_row = db(db.computers.FILEID == request.args(0)).select()
download_file = download_row.filefieldreturn download_file
However, I'm not entirely sure what I need to write in order for this to
work.
