DjangoPatchMutation

Will update an existing instance of a model. The PatchMutation (in contrast to the UpdateMutation) does not require all fields to be supplied. I.e. all are fields are optional.

Mutation input arguments:

Argument	Type
id	ID!
input	Object!

All meta arguments:

Argument	type	Default	Description
model	Model	None	The model. Required.
only_fields	Iterable	None	If supplied, only these fields will be added as input variables for the model
exclude_fields	Iterable	None	If supplied, these fields will be excluded as input variables for the model.
