Comment (by Vladimiroff): The reason behind this is that `subclassa` (in the given example) is not technically a **field**. Which means it won't be returned by `Base._meta.get_concrete_fields_with_model`. The only solution I could think of is creating `get_all_concrete_fields_with_model` (which should use `get_all_field_names` instead of `local_fields`). Anyone with better ideas? -- Ticket URL: <https://code.djangoproject.com/ticket/23270#comment:3> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
