Context

• Package Version: django-forestadmin==1.5.0
• Django Version: Django==3.2.19

Is there a setting to ignore certain models? I've identified the model and I'm not really that interested in it in Forest Admin

Hello @dmarkey, Yes we have a setting to ignore models in forest, but currently missing in the documentation (I will handle this soon). You can use it by modifying your settings.py :

FOREST = {
    'FOREST_ENV_SECRET': os.environ.get('FOREST_ENV_SECRET'),
    'FOREST_AUTH_SECRET': os.environ.get('FOREST_AUTH_SECRET'),
    'EXCLUDED_MODELS': ['django_content_type', 'django_migrations'],
}

Let me know if it works on your side.

Regards.

I just updated the documentation for this topic. It is available here: https://docs.forestadmin.com/documentation/extra-help/settings/include-exclude-models

[dmarkey]

Great! I'll try this workaround later.

On the root cause, do you need any further information? I suggest a helpful error message rather than this ugly stack trace at least.

[jbarreau]

That should be great if you can provide me an example of Model (just the relationship) that create this error (if you know which one of your model generate it) because I can't reproduce this error on my side.

Is your project running without django-forestadmin ? That's sounds like a dumb question, but at the end of the stacktrace, there is a Django error, and I can't find on google anything else than source code of Django that deal with this issue.

I closed this issue because it stale.
