The basic idea is that there is a step type, that can be annotated with a "type" field: from typing import Literal, Union, List from pydantic import Field from typing_extensions import Annotated import pydantic import sys class Type1Step(pydantic.BaseModel): step_type: Literal["type_1"] ...
# 需要导入模块: import pydantic [as 别名]# 或者: from pydantic importBaseModel[as 别名]def__init__(self, target:BaseModel, allow_failure: bool = True, always_apply: bool = False):# Checks against already instanced and uninstanced classes while avoiding unhahsable type errorifnotalways_ap...
class UserModel(BaseModel): username: str = Field(default=None, description='姓名', min_length=3, max_length=16) weight: int = Field(default=0, description='体重', gt=60, lt=90) # gt 大于 lt 小于 age: int = Field(default=18, description='年龄', ge=18, le=50) # ge 大于等于 ...
在上述示例中,MyModel是一个继承自BaseModel的数据模型类,其中my_list是一个列表字段,类型注解为List[int],并通过default参数指定了初始值为[1, 2, 3, 4, 5]。创建MyModel对象后,可以通过访问my_list字段来获取列表的值。 Pydantic的优势在于它提供了强大的数据验证和解析功能,可以帮助开发人员轻松处理数据的验...

您可以只排除通过将设置为的模型字段和不是非的模型字段进行合并而未设置的可选模型字段。
