+    when resolving the ``DjangoObjectType``, even through related objects.
+    Note that because of this, benefits from using ``select_related``
+    in objects that define a relation to this ``DjangoObjectType`` will be canceled out.
+    In the case of ``prefetch_related``, the benefits of the optimization will be lost only

+
+
+    If you want to explicitly disable the execution of the custom ``get_queryset`` when resolving,
+    you can decorate the resolver with `@graphene_django.bypass_get_queryset`. Note that this

+DjangoFormInputObjectType
+~~~~~~~~~~~~~~~~~~~~~~~~~

+``DjangoFormInputObjectType`` is used in mutations to create input fields by **using django form** to retrieve input data structure from it. This can be helpful in situations where you need to pass data to several django forms in one mutation.

Any data field, which have choices in django, with value ``A_1`` (for example) from client will be automatically converted to ``1`` in mutation data.
