Assignment List extension w/o JupyterHub #922

Closed gtolomei closed 6 years ago

gtolomei commented 6 years ago

Hi everyone,

I have successfully installed nbgrader version 0.5.4 on mac OS High Sierra (version 10.13.2) in combination with jupyter notebook 5.2.2 using conda 4.4.7. AFAIK, all nbgrader and server extensions are fully installed and enabled when nbgrader is installed using conda. This is indeed my case, and I can easily verify it by typing the following command:

jupyter nbextension list jupyter serverextension list

Now, the thing is that I won't be using nbgrader in combination with JupyterHub; in fact, I'm gonna distribute assignments created with nbgrader without using the nbgrader release command yet using my institution's internal learning management system (i.e., Moodle), according to what is described in the user documentation.

Because of that, I haven't setup any exchange directory at all; in particular, I didn't create any /srv/nbgrader/exchange directory on my local filesystem (assuming to keep the default setting for that). Of course, when I click on the Assignments tab on my Jupyter Notebook dashboard I get the following error message (please, see the image attached below), which basically complains about the fact that the (default) exchange directory above cannot be found.

Thus, my question is: even though I won't be using any exchange directory to distribute my assignments, should I anyway create that directory in my local filesystem or should I instead disable the assignment list extension? If the latter, am I still guaranteed everything keeps working given that - here I'm quoting from user documentation - "To work properly, the assignment list, formgrader, and validate extensions require both the nbextension and serverextension"?

Any help will be much appreciated.

Thanks, G.

Hi Gabriele,

The assignment list extension is only for when you are distributing/collecting assignments from your students using nbgrader, so in your case you wouldn't want to use it. The best option here would be to disable the assignment list extension.

If the latter, am I still guaranteed everything keeps working given that

  • here I'm quoting from user documentation - "To work properly, the assignment list, formgrader, and validate extensions require both the nbextension and serverextension"?

Yes, everything will still work correctly. The wording of the documentation is perhaps a bit confusing---what it means is that each of the assignment list, formgrader, and validate extensions have two parts to them: a nbextension and a serverextension. So to make sure each of the assignment list/formgrader/validate extensions work, you have to make sure both the corresponding nbextension and serverextension are enabled (so there are 6 separate pieces you could enable/disable total). If you want to disable an extension (for example the assignment list extension) you should disable both the nbextension and serverextension parts for it.

Hope that helps to clear things up!

Cheers, Jess
