check_user_model

Validates the custom user model configuration by checking that REQUIRED_FIELDS is a list or tuple, the USERNAME_FIELD is not included in REQUIRED_FIELDS, and the username field is unique. It also ensures that is_anonymous and is_authenticated are attributes or properties rather than methods to prevent security vulnerabilities.

def check_user_model(
    app_configs: list or None = null,
    **kwargs: dict = null
) - > list

Validates the configuration of the custom user model to ensure it adheres to Django's authentication requirements. This function checks for common configuration errors such as improper REQUIRED_FIELDS definitions, non-unique username fields, and incorrect property implementations for is_anonymous or is_authenticated.
