Describe the bug
Hello guys, the option exclude_unset=True isn't working for me for some reason:

Versions (please complete the following information):

• Python version: 3.12.1
• Django version: 5.0.1
• Django-Ninja version: 1.1.0
• Pydantic version: 2.6.4

Here is the snippet code:

class ContractSchemaInput(ModelSchema):
    sender_id: int
    client_id: int
    type_id: int
    price_frequency: Literal["minute", "hourly", "daily", "weekly", "monthly"]
    care_type: Literal["​ambulante", "accommodation"]
    attachment_ids: list[str] = []

    class Meta:
        model = Contract
        exclude = ("id", "type", "sender", "client", "updated", "created")

@router.patch("/contracts/{int:id}/update", response=ContractSchema)
def update_client_contract(request: HttpRequest, id: int, contract: ContractSchemaInput):
    print("Payload:", contract.dict(exclude_unset=True))
    Contract.objects.filter(id=id).update(**contract.dict(exclude_unset=True))

    return get_object_or_404(Contract, id=id)

Output error:

{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "body",
        "contract",
        "sender_id"
      ],
      "msg": "Field required"
    },
    {
      "type": "missing",
      "loc": [
        "body",
        "contract",
        "client_id"
      ],
      "msg": "Field required"
    },
    {
      "type": "missing",
      "loc": [
        "body",
        "contract",
        "type_id"
      ],
      "msg": "Field required"
    },
    {
      "type": "missing",
      "loc": [
        "body",
        "contract",
        "care_type"
      ],
      "msg": "Field required"
    },
    {
      "type": "missing",
      "loc": [
        "body",
        "contract",
        "start_date"
      ],
      "msg": "Field required"
    },
    {
      "type": "missing",
      "loc": [
        "body",
        "contract",
        "end_date"
      ],
      "msg": "Field required"
    },
    {
      "type": "missing",
      "loc": [
        "body",
        "contract",
        "care_name"
      ],
      "msg": "Field required"
    }
  ]
}

Please any suggestions?

Your fields are all marked as required, you'll need to set a default to make them not. Basically the opposite of https://docs.pydantic.dev/latest/concepts/models/#field-ordering also https://django-ninja.dev/guides/response/django-pydantic/#making-fields-optional
