Mechanism to Load Notebook

[phreed]

When working in python notebooks normally I just drop the notebook file where the server expects to find them.
When working with Sandstorm how are we to upload/load/import notebook files, and other supporting python files?

Unfortunately, this isn't easy at the moment.

The best solution for now is probably to backup the grain (click the "Download Backup" button with the grain open), and then edit the zip file yourself. Either replace the Sandstorm.ipynb file with your own/add your own scripts, then re-zip it and restore it under the "My Files" tab.

I just tried the edit-the-zip-file approach, but I got "Upload failed: 500 Internal Server Error" when I uploaded the results.

I didn't really expect it to work... sandstorm apps are signed and editing the zip file would break the signature, no? Maybe I'm confusing grains and apps.

Anyway... the diagnostic isn't helpful.

Apps (eg. the .spk files that you use to install apps) are signed with the app developer's key. Backups of grains are currently just normal zip files and can be edited at will.

Can you take a look at the sandstorm.log file (by default at /opt/sandstorm/var/log/sandstorm.log) and see if it has any helpful errors logged?

tee hee... I used the "upload an app" button. No wonder it didn't work.

Restore backup works fine.

One gotcha that caught me: be sure to create the zip file w/out a "containing directory." E.g. run zip -r backup.zip . where . is the root directory of the unzipped backup. If the directory structure of the uploaded zip doesn't match what Sandstorm expects, you'll get a 200 error on upload.

It still would be really nice to accept uploaded notebooks in-app. The Lychee app supports uploads... why can't iPython notebook?
