resolve timedelta field doesn't work

[jankrnavek]

In WorkerOut ModelSchema bellow I am not get to work pydantic field resolve_runtime_sec that converts timedelta orm field to seconds.
For debug purposes I added a row that works correctly.

Thanks,
H.

class WorkerOut(ModelSchema):
    runtime_sec: float = Field(0)

    @staticmethod
    def resolve_runtime_sec(obj) -> float:
        # print(obj.runtime.total_seconds())  # a debug row - a timedelta method that prints seconds correctly
        return obj.runtime.total_seconds()

    class Meta:
        model = Worker
        exclude = [
            "id",
            "runtime",
        ]
