model_dump()'s exclude keyword argument doesn't exclude keys named the same thing in nested models

[SeaswimmerTheFsh]

So, I have four classes...

• AuroraBaseModel

  • Subclasses pydantic.BaseModel

class AuroraBaseModel(BaseModel):
    """Base class for all models in Aurora."""
    model_config = ConfigDict(ignored_types=(Red,), arbitrary_types_allowed=True)
    bot: Red

    def to_json(self, indent: int = None, file: Any = None, **kwargs):
        from aurora.utilities.json import dump, dumps
        return dump(self.model_dump(exclude={"bot"}), file, indent=indent, **kwargs) if file else dumps(self.model_dump(exclude={"bot"}), indent=indent, **kwargs)

• AuroraGuildModel

  • Subclasses AuroraBaseModel
  • Mostly identical to it's parent class, but has a single extra attribute and an updated to_json() method to match.

class AuroraGuildModel(AuroraBaseModel):
    """Subclass of AuroraBaseModel that includes a guild_id attribute, and a modified to_json() method to match."""
    guild_id: int

    def to_json(self, indent: int = None, file: Any = None, **kwargs):
        from aurora.utilities.json import dump, dumps
        return dump(self.model_dump(exclude={"bot", "guild_id"}), file, indent=indent, **kwargs) if file else dumps(self.model_dump(exclude={"bot", "guild_id"}), indent=indent, **kwargs)

• Moderation

  • Subclasses AuroraGuildModel
  • One of it's attributes, changes, is a list of Changes

class Moderation(AuroraGuildModel):
    moderation_id: int
    timestamp: datetime
    moderation_type: str
    target_type: str
    target_id: int
    moderator_id: int
    role_id: Optional[int] = None
    duration: Optional[timedelta] = None
    end_timestamp: Optional[datetime] = None
    reason: Optional[str] = None
    resolved: bool
    resolved_by: Optional[int] = None
    resolve_reason: Optional[str] = None
    expired: bool
    changes: List["Change"]
    metadata: Dict

• Change

  • Subclasses AuroraBaseModel

class Change(AuroraBaseModel):
    type: Literal["ORIGINAL", "RESOLVE", "EDIT"]
    timestamp: datetime
    reason: str
    user_id: int
    duration: Optional[timedelta] = None
    end_timestamp: Optional[datetime] = None

Whenever I use my to_json() method on an instance of Moderation, I get an error saying that it can't JSON serialize the Red type. Alright, that's an easy enough fix - but it isn't, because I'm already excluding the bot attribute from my model_dump() invocation, so my conclusion is that model_dump()'s exclusions don't effect nested models. Is there a workaround for this?
