如何才能使一个具有化脓性模型的人

Question

我对化脓性药物很陌生，而且被困住了。下面的代码正在抛出错误TypeError：Type is not JSON serializable: Person

from pydantic import BaseModel,Extra
from typing import Mapping, Optional, Any,List
from orjson import dumps

class Address(BaseModel):
    place: str

class Person(BaseModel):
    name: str
    age: int
    address: Mapping[str, str]={}
    class Config:
        anystr_strip_whitespace: True
        extra: Extra.allow
        allow_population_by_field_name: True

person={'name':'tom','age':12,"gender":"male"}
person=Person(**person)
person.address['place']='XYZ'
dict={'class':'X','person':person}

dumps(dict)

知道该怎么做吗？

Answer 1

您需要使用Pydantic方法.dict()将模型转换为Python字典。

重要的是，您要将字典分配给Python类型！使用与“dict”不同的变量名，如下所示：“data_dict”。

以下是您的解决方案：

from pydantic import BaseModel,Extra
from typing import Mapping, Optional, Any,List
from orjson import dumps

class Address(BaseModel):
    place: str

class Person(BaseModel):
    name: str
    age: int
    address: Mapping[str, str]={}
    class Config:
        anystr_strip_whitespace: True
        extra: Extra.allow
        allow_population_by_field_name: True

person={'name':'tom','age':12,"gender":"male"}
person=Person(**person)
person.address['place']='XYZ'
data_dict={'class':'X','person':person.dict()}

dumps(data_dict)
