Json Parse for Environment Variables in sub models does not work about pydantic-settings HOT 3 CLOSED

Sorry for the slow reply.

Can't read your code, so hard to tell, might be the same as #27.

from pydantic-settings.

I face the exact same issue. Is there a fix to put complex datatypes like in nested classes and fill them with the notation with env_nested_delimiter e.g. export BASE_CONFIG__NESTED_CONFIG = '["ListElement0", "ListElement1"]'?

from pydantic-settings.

We improved parsing nested models values in pydantic-settings.

FYI, pydantic-settings now is a separate package and is in alpha state. you can install it by pip install pydantic-settings --pre and test it.

Here is your example in pydantic-settings:

import os
from typing import List, Optional

from pydantic import BaseModel, ConfigDict
from pydantic_settings import BaseSettings


class SubModel(BaseModel):
    v1: Optional[str] = None
    l1 : List[str] = None


class Settings(BaseSettings):
    sub_model: SubModel = None

    model_config = ConfigDict(env_nested_delimiter='__')

os.environ['sub_model__l1'] = '["1","2","3"]'

global_config = Settings()
print(global_config.model_dump())
