pydantic

问题 Sorry, not proficient in Python. I haven't found the docs for that use case.

How can I use pydantic with this kind of inheritance? I

问题 When assigning an incorrect attribute to a Pydantic model field, no validation error occurs. from pydantic import BaseModel class pyUser(BaseModel): username: str class Config: validate_all = True validate_assignment = True person = pyUser(username=1234) person.username >>>1234 try_again = pyUser() pydantic.error_wrappers.ValidationError: [ErrorWrapper(exc=MissingError(), loc=('username',))] <class '__main__.pyUser'> How can I get pydantic to validate on assignment? 回答1: It is expected

问题 In the following code, I need to declare my_attr as anything except None . What should I exchange Any for? from pydantic import BaseModel from typing import Any class MyClass(BaseModel): my_attr: Any 回答1: To achieve this you would need to use a validator, something like: from pydantic import BaseModel, validator class MyClass(BaseModel): my_attr: Any @validator('my_attr', always=True) def check_not_none(cls, value): assert value is not None, 'may not be None' return value But it's unlikely
