Override model fields of an abstract model baseclass in django, by removing them from the abstract model.

meta.py

def AbstractClassWithoutFieldsNamed(cls, *excl):
    """
    Removes unwanted fields from abstract base classes.

    Usage::
    >>> from oscar.apps.address.abstract_models import AbstractBillingAddress

    >>> from koe.meta import AbstractClassWithoutFieldsNamed as without
    >>> class BillingAddress(without(AbstractBillingAddress, 'phone_number')):
    ...     pass
    """
    if cls._meta.abstract:
        remove_fields = [f for f in cls._meta.local_fields if f.name in excl]
        for f in remove_fields:
            cls._meta.local_fields.remove(f)
        return cls
    else:
        raise Exception("Not an abstract model")

Haha, just found while looking to achieve the same for an Oscar project, until django-oscar/django-oscar#1940 is merged. Thanks! :)

Glad to hear it's useful to someone.

💥 💯% useful. Thanks

Fortunately, this is no longer necessary in 1.10 since you can override fields on an abstract model.
