Multiple file download

[sasogeek]

Is there a way I could download all the files in a db or loop through a db selection and download all associated files via maybe just a click on a link?

I think you'd have to loop through a selection and use retrieve() (http://pydal.readthedocs.org/en/latest/index.html?highlight=retrieve#pydal.objects.Field.retrieve)

If you need a one-click download then perhaps you could zip all the files using the zip library (or gzip or whatever compression you want to use ^^)

I zipped the files and saved it in a folder...but how do I download it now? using the the download function doesn't work...

I managed to get it working. I looked up the download method in the Response class and apparently it's looking for a table name and field in the file name. I added that structure [table.field.] to my zipped file name [table.field.zipfile_name.zip] and passed it to the download as an argument in URL() and now it works. it zips the file, saves it, then downloads it, Now the next thing I want to do is delete the saved zip file from inside my app once it has been downloaded.

A solution could be to use the scheduler to periodically clean your fs
from zip files older than a reasonable amount of time...

Alternatively, you could also use a tempfile : https://docs.python.org/2/library/tempfile.html
