feature request: Load multiple .env files from different paths, or additionally support .ini files about pydantic-settings HOT 7 OPEN

The specific scenario is a project that operates in sub-modules. There is a top-level parent class that is configured through Config, but this cannot realize the loading of global env and sub-module env. After reading the specific code, the specific env call will only call the data source when it is specifically instantiated in the Settings subclass, so it can support the feature I mentioned

from pydantic-settings.

good idea. I think it shouldn't be too hard to implement

yeah，In the data source configuration class, implement the env source in the form of a list, and in the read method, process multiple env sources, which should be fine

from pydantic-settings.

After checking the code I realized pydantic-settings already have this feature. and you can have multiple env files.

take a look at this test

It looks like you need to have a ConfigDict variable in the Settings class, but I actually think that you can store the corresponding value of the corresponding variable in the Settings class. I don't know if ConfigDict can provide variable hinting, after all, code hinting is still quite important

Maybe I should provide a simple example to further illustrate my idea？

from pydantic-settings.

It seems that the above test cases are not the functions I want to express. The following are the test cases I provided, hoping to help communicate

# import module
from pydantic import ConfigDict, BaseSettings
from pydantic.env_settings import SettingsSourceCallable
from typing import Tuple


# in main project
class ParentSettings(BaseSettings):
    project_home: str = '.'

    class Config:
        # the env_file should allow multi source file
        env_file = '.env'  
        # such as env_file = ['.env', 'sub_module.env']  sub_module.env usually a dynamically generated path
        env_file_encoding = 'utf-8'
        extra = 'allow'
    
        @classmethod
        def customise_sources(
            cls,
            init_settings: SettingsSourceCallable,
            env_settings: SettingsSourceCallable,
            file_secret_settings: SettingsSourceCallable,
        ) -> Tuple[SettingsSourceCallable, ...]:
            return (
                init_settings,
                env_settings,
                file_secret_settings
            )


# in sub module
class ChildSettings(ParentSettings):
    # i hope the var can auto load from sub module .env file by the parent class‘s Config class
    sub_module_var: str = '.'

The above is my specific usage scenario, because I am using it in the production environment, and the v2 version of pydantic is still in the development stage, so use v1 as an example
