#20853 closed Bug (wontfix)

Cannot find documentation on Options.module_name and Options.model_name

I'm using Django 1.5 and looking at the docs here:

As per I'm trying to create a python metaclass to append a string at the end of my model's permissions. However I could not find documentation on Options.module_name (it seems to return the model name). Furthermore I get that 'Options' object has no attribute 'model_name', but I saw this attribute being used in some other code on the internet.

See #19689 - I believe this attribute is considered a private API and thus undocumented.

Resolution: wontfix

As pointed out by @timo the model _meta option is deliberately undocumented since it's considered an internal API and thus isn't bound to Django's backward compatibility policy.

However as the deprecation of module_name path taken in #19689 pointed out we're aware this API is (ab)used in the wild and chose to deprecate it as if it was public to prevent breakages in third-party applications.

The reason you're getting this AttributeError upon _meta.model_name access is that property was only introduced in Django 1.6. I'm afraid you'll have to access _meta.module_name and lower case it on Django < 1.6 to get the same result.

I know this is an old bug, and what I'm suggesting is probably a very bad idea, but in my case I'm stuck on 1.4.2 for a moment and need to use a module that has been updated to the latest >=1.6 Django versions.

# Monkey Patch
from django.db.models.options import Options
def monkeypatch__options__model_name(self):
    return self.module_name.lower()
Options.model_name = monkeypatch__options__model_name
