TenantFormset(data=self.data, instance=instance, prefix='TENANTS_%s' % pk_value) where instance is an instance of Building, the "parent" or container for tenants and self is an instance of class BaseBuildingFormset(BaseInlineFormSet) which is instantiated like this: BuildingFormset = inlineformset_factory(models.Block, models.Building, formset=BaseBuildingFormset, extra=1) I omitted to mention that to get around this I stopped passing in self.data, which led to the behaviour that I described in my original post. Apologies if this misled anyone. Up to Django 1.2.5, Nathan's code works fine. However at 1.3, if self.data is passed to TenantFormset, it turns out to be empty and a ValidationError is raised because the ManagementForm information has not been supplied. This is the intended consequewnce of #11418, AFAICT. Working on the assumption that self.data should contain the ManagementForm data I've tried populating it with said data, but ValidationError is still raised. My use case is slightly simpler than Nathan's example as I just need to edit existing objects, so I'm going to try populating the formsets using querysets rather than instances. Does anyone have any other ideas on how this might be made to work? Cheers, Kev -- You received this message because you are subscribed to the Google Groups "Django users" group.
