Polymorphic formsets support.
|
|
|
|
This allows creating formsets where each row can be a different form type.
|
|
The logic of the formsets work similar to the standard Django formsets;
|
|
there are factory methods to construct the classes with the proper form settings.
|
|
|
|
The "parent" formset hosts the entire model and their child model.
|
|
For every child type, there is an :class:`PolymorphicFormSetChild` instance
|
|
that describes how to display and construct the child.
|
|
It's parameters are very similar to the parent's factory method.
|
|
|
|
See:
|
|
* :func:`polymorphic_inlineformset_factory`
|
|
* :class:`PolymorphicFormSetChild`
|
|
|
|
The internal machinery can be used to extend the formset classes. This includes:
|
|
* :class:`BasePolymorphicModelFormSet`
|
|
* :class:`BasePolymorphicInlineFormSet`
|
|
* :func:`polymorphic_child_forms_factory`
|
|
|
|
For generic relations, a similar set is available:
|
|
* :class:`BasePolymorphicGenericInlineFormSet`
|
|
* :class:`PolymorphicGenericFormSetChild`
|
|
* :func:`polymorphic_generic_inlineformset_factory`
