Release button dose not work normally (Jupyterhub with dockerspawner )

[guyq1997]

Hello Guys,

i am using ngshare in Jupyterhub with dockerspawner.

Everything goes well if i only use nbgrader.

After i used ngshare, and specify the exchange directory to ngshare API (/services/ngshare). The Release Button does not work.

The Log reported 'Successfully released':

But actually there is nothing released, and the Status has not changed at all:

But i can see the Assignments are successfully stored in /srv/ngshare of jupyterhub container.

Hello @guyq1997,

we ran into a similar problem and after days(!) of investigation we found out the following:

• When ngshare is installed with pip the "regular" way (i.e. pip install ngshare) and using pip list it shows SQLAlchemy in Version 2.0.30 (however its clearly bounded to a version < 2.0 as you can see here: https://github.com/LibreTexts/ngshare/blob/master/setup.py)
• When ngshare is installed with pip -e /path/to/freshly-checked-out-ngshare-source-code/here pip list shows SQLAlchemy in a compatible version (1.4.53 in our case) - and everything seems to work just fine.

Have a look here:

Whether it is a pip issue or bug in setuptools, we do not know yet. I hope, the folks at LibreTexts can have a look at it.

I hope, that this information may help you figure out, why you are also unable to do write operations to the sqlite-db (fileupload was working on our side as well)

Cheers

The limit < 2.0 of SQLAlchemy was introduced after the release of v0.6.0.

But it is easy to set this limit manually:

pip install ngshare "SQLAlchemy<2.0"

Hi Ykazakov,

thank you for clarifying. that explains the different behaviour.

its very irritating (to say the least) to have an officially released version 0.6.0 that actually does not work. no indication, hints, warnings, logs (while executing the code or in the documentation) ... failing quietly is considered very bad practice. please release the fix of this particular severe bug as a new version as soon as possible.

and no: one does NOT want to install specific version of a subpackage when adding a dependency. we want to add a sound and consistent package installed in a specific version.

Cheers
