Problems with nested settings in pydantic-settings v2.2.1

[MartiAndrew]

Hello, please help me with issue:

Available:

pydantic v 2.6.3 pydantic-factories v 1.17.3 pydantic-settings v 2.2.1

script:

class WebSettings(BaseSettings):
    model_config = SettingsConfigDict(
        env_prefix=f"{ENV_PREFIX}WEB_",
        env_file=PROJECT_ROOT.joinpath(".env"),
        env_file_encoding="utf-8",
    )

    host: str = "127.0.0.1"
    port: int = 8000
    workers_count: int = 1

class SentrySettings(BaseSettings):

    model_config = SettingsConfigDict(
        env_prefix=f"{ENV_PREFIX}SENTRY_",
        env_file=PROJECT_ROOT.joinpath(".env"),
        env_file_encoding="utf-8",
    )

    dsn: str = ""
    traces_sample_rate: float = 0.05

class Settings(BaseSettings):

    model_config = SettingsConfigDict(
        env_prefix=ENV_PREFIX,
        env_file=PROJECT_ROOT.joinpath(".env"),
        env_file_encoding="utf-8"
    )

    web: WebSettings = WebSettings()

    sentry: SentrySettings = SentrySettings()

I set env_variables, but These variables were used in classes for which they were not intended. This behavior came as a surprise. When I run the project I get the error:

pydantic_core._pydantic_core.ValidationError: 7 validation errors for WebSettings

Atypical behavior after changing pydantic-settings version to 2.2.1 How to solve this problem? thank you in advance.

It is related to this issue https://github.com/pydantic/pydantic-settings/issues/245 You can fix the problem by adding extra='ignore' config

Thank you very much Hasan, I almost reached this solution myself, but it was just a little bit short. Thanks for your work again.
