Originally created by @kuhball on GitHub (Nov 1, 2023).

NetBox version

v3.6.4

Python version

3.10

Steps to Reproduce

  1. Create a datasource containing a custom validator class within a python file
  2. Import the class within the gui via admin / current config using the displayed path within the datasource
  3. Try to create / edit the model the validator is applied to

Expected Behavior

The class can be imported and used as a validator analog to custom scripts.

Due to the new admin menu the current config and custom validator settings can be accessed from the ui. This would make a great addition to reduce manual configuration within the netbox host.

Not sure if this correctly classified as a bug or rather a FR.

Observed Behavior

The class cannot be found when using the displayed path from the ui.

What you're trying to do is not supported. Custom validator classes must be loaded into the Python virtual environment at runtime; they cannot be read from a remote file.
