ordered = True from marshmallow overriden by EnumField() in Schema

[Carton32]

Hi,

I'm using marshmallow_enum to handle the serialization of my Enum.

I have the following code :

class EntitySchema(ma.SQLAlchemyAutoSchema):

    class Meta:

        ordered = True

    def on_bind_field(self, field_name, field_obj):

        field_obj.data_key = camelcase(field_obj.data_key or field_name)

class Meter(Entity):

    model = db.Column(db.Enum(MeterModel), nullable=False)
    description = db.Column(db.String(100))
    location = db.Column(db.String(100))
    bus_protocol = db.Column(db.Enum(BusProtocol), nullable=False)
    bus_serial_address = db.Column(db.String(20), nullable=False)
    primary_address = db.Column(db.Integer, nullable=False)
    secondary_address = db.Column(db.Integer)
    baudrate = db.Column(db.Integer, nullable=False)
    bytesize = db.Column(db.Integer, default=8, nullable=False)
    parity = db.Column(db.String(1), nullable=False)
    stopbits = db.Column(db.Integer, nullable=False)
    password = db.Column(db.Integer)

class MeterSchema(EntitySchema, ma.SQLAlchemyAutoSchema):

    model = EnumField(MeterModel)
    bus_protocol = EnumField(BusProtocol)

    class Meta:
        
        #fields = ("id", "remote_id", "created_at", "updated_at", "model", "description", "location", "bus_protocol", "bus_serial_address", "primary_address", "secondary_address", "baudrate", "bytesize", "partiy", "stopbits", "password")
        model = Meter

When I retrieve a meter from my SQLite3 DB, I get the following JSON :

{
    "model": "SDM630V2CT",
    "busProtocol": "MODBUS",
    "id": 1,
    "remoteId": null,
    "createdAt": "2020-09-02T08:00:30",
    "updatedAt": "2020-09-02T08:00:30",
    "description": "Test meter",
    "location": "Office",
    "busSerialAddress": "/dev/ttyUSB0",
    "primaryAddress": 1,
    "secondaryAddress": null,
    "baudrate": 38400,
    "bytesize": 8,
    "parity": "N",
    "stopbits": 1,
    "password": null
}

As we can see, with "fields" commented out, "model" and "busProtocol" get on top of the JSON and don't respect anymore ordered = True inherited from EntitySchema. I would love to have all my JSON completely ordered and if I don't have to use fields = (...), it would be awesome because I don't want to have to change at multiple points the name of my DB fields.

Maybe it's an issue or maybe something exists to avoid this but I didn't find anything.
