To my regret, Django model inheretance, is not yet working. More info here: http://code.djangoproject.com/wiki/ModelInheritance We have also found this. Building quick sites is very easy with Django. Building 'framework' to build something is difficult. For example here, we are making a e-commerce software framework based on Django. Every e-commerce store have its own set of attributes associated with product. To make it possible, we have created basic models (Product,Category) and related customProduct, customCategory to them. This allows end users and developers to extend models, without inheritance, and without touching basic tables. All this is working via OneToOne relationship, which is not yet fully supported in Django, so we maintain 5 patches to Django source code only to make our software working.
