download dataset using local copy about bioblend

[afgane]

You mean, get a path to a dataset from inside Galaxy and copy it elsewhere on a local system? Ideally, things stay inside Galaxy so they can be shared, referenced, and all to support reproducibility.
The reality of it is that people may want to pull things out though so it's a feature like this probably wouldn't hurt much. Hopefully someone else chimes in leaning one way or another...

That's exactly what I mean. Sometime you have no choice but to pull out dataset(s) so the can be used in application not available in Galaxy. I.e Viewing bam files in Tablet or downloading .sqn file for genome submission.

The path of the file is already available for admin users using gi.datasets.show_dataset(dataset_id)['file_name']. Is that enough?

[hexylena]

There's a flag you can pass in Galaxy's config that exposes the real dataset path. It's used in (I think) CSIRO's Galaxy VMs in order to allow other services to connect to galaxy and pull data as they're running under the same user. Perhaps this is a similar scenario to what @Takadonet is referring to?

expose_dataset_path directive in config/galaxy.ini would indeed expose the dataset path also to non-admin users, which can again be retrieved with gi.datasets.show_dataset(dataset_id)['file_name'].
