Unable to access c.Spawner from any other file than jupyterhub_config.py file

[Ayush_Singla]

I am trying to modularize my code and i have a custom_spawner.py. In that i am trying to assign the options_from_form but i am getting the following

c.Spawner.options_from_form = options_from_form ││ ^^^^^^^^^ ││ AttributeError: 'function' object has no attribute 'Spawner'

Also incase i am extending the kubspawner class to make my own custom_spawner, shouldn’t simply overriding the function option_from_form be sufficient? i tried doing this but the function is not being called for some reason.

any help is much appreciated !

c.Xxx is only for configuration. If you want to modify the spawner you’ll need to subclass it. Here’s an example:

How to parse mem_lim and cpu_lim using options_form in DockerSpawner?

Can you try with this snippet? I m not sure if it works, but config should be something like this. In your config, you are instantiating an object out of spawner class and calling get_memo() directly on it. You should provide just the class and it is JupyterHub’s responsibility to instantiate spawner object and call the methods properly to parse the options from form before spawning a single user server.
