我正在尝试在 Fastapi-users pydantic 架构中构建自定义字段,如下所示: classUserRead(schemas.BaseUser[uuid.UUID]):twitter_account: Optional['TwitterAccount'] Run Code Online (Sandbox Code Playgroud) 在UserRead 验证上 Pydantic 返回 field required (type=value_error.missing) Run Code Online (Sandbox C...

由于v1.2 版本注释仅适用于可空字段(Optional[…], Union[None, …] and Any)和带省略号(…)的可空字段作为默认值,不再表示相同的内容。 代码语言:javascript 复制 from typingimportOptional from pydanticimportBaseModel,Field,ValidationErrorclassModel(BaseModel):a:Optional[int]b:Optional[int]=...c:Option...
title:str= Field(max_length=50, title="组织名称", description="组织名称") street:Optional[str] = Field(max_length=255, title="街道具体地址", description="街道具体地址", default="") latitude:str= Field(description="经度") longitude:str= Field(description="纬度") ...
field required (type=value_error.missing) 另一方面,如果传入值多于定义值时,BaseModel也会自动对其进行过滤。如: p=Person(name="Tom",gender="man",age=24)print(p.json())#{"name":"Tom"} 可以看到,额外的参数gender与age都被自动过滤了。
