Field(..., validation_alias='foo') Field(..., serialization_alias='foo') 该alias参数用于验证和序列化。如果您想分别为验证和序列化使用 不同的别名,则可以使用validation_alias 和serialization_alias参数,它们仅适用于各自的用例。 from pydantic import BaseModel, Field class User(BaseModel): name: str...
validation_alias 字段定义别名,只想将别名用于验证 serialization_alias 字段定义别名,只想定义用于序列化的别名 gt、lt、ge等 约束数值,大于、小于、大于或等于等 min_length、max_length等 约束字符串 min_items、max_items等 元组、列表或集合约束 validate_default 控制是否应验证字段的默认值,默认情况下,不验证...
Python Pydantic Alias Introduction In Python programming, Pydantic is a library that provides data validation and parsing using Python type annotations. It allows you to define data schemas, validate and parse input data, and serialize data to different formats. One of the useful features offered by...
Field( validation_alias=pydantic.AliasPath("level1", "level2", "my_str"), ) m = MyConfig.model_validate({"level1": {"level2": {"my_str": "a"}}}) print(m.my_str) Of course this does not handle serialization. Member Viicos commented Sep 1, 2023 Of course this does not ...
