Description

I'm using Django 1.5 and looking at the docs here: https://docs.djangoproject.com/en/1.5/ref/models/options/

As per http://stackoverflow.com/questions/725913/dynamic-meta-attributes-for-django-models 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.

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.
