I can to this to make it work: {{{ # Because ModelFormMetaclass will call get_declared_fields method with # with_base_fields=False, we modify it with True. from django.newforms import models as nmodels gdf = nmodels.get_declared_fields nmodels.get_declared_fields = \ lambda bases, attrs, with_base_fields: gdf(bases, attrs, True) }}} But it will be nice if this behavior is default behavior. Thanks. nobody bear330   0 0 0 0 0 0
