pydantic model config_wrangler.config_templates.aws.dynamodb.DynamoDB

Bases: AWS_Session

Config:

• validate_default: bool = True

• validate_credentials: bool = True

Fields:

• scan_progress_seconds (int)

• user_id ()

• password_source ()

• raw_password ()

• keyring_section ()

• keepass ()

• keepass_group ()

• keepass_title ()

• validate_password_on_load ()

Validators:

• check_model » all fields

field keepass: KeepassConfig | None = None

If the password_source is KEEPASS, then load a sub-section with the config_wrangler.config_templates.keepass_config.KeepassConfig) settings

Validated by:

• check_model

field keepass_config: str | None = 'keepass'

If the password_source is KEEPASS, then which root level config item contains the settings for Keepass (must be an instance of config_wrangler.config_templates.keepass_config.KeepassConfig)

Validated by:

• check_model

field keepass_group: str | None = None

If the password_source is KEEPASS, which group in the Keepass database should be searched for an entry with a matching entry.

If is None, then the KeepassConfig.default_group value will be checked. If that is also None, then a ValueError will be raised.

Validated by:

• check_model

field keepass_title: str | None = None

If the password_source is KEEPASS, this is an optional filter on the title of the keepass entries in the group.

Validated by:

• check_model

field keyring_section: str | None = None

If the password_source is KEYRING, then which section (AKA system) should this module look for the password in.

See https://pypi.org/project/keyring/ or https://github.com/jaraco/keyring

Validated by:

• check_model

field password_source: PasswordSourceValidated | None = None

The source to use when getting a password for the user. See PasswordSource for valid values.

Validated by:

• check_model

field raw_password: str | None = None

This is only used for the extremely non-secure CONFIG_FILE password source. The password is stored directly in the config file next to the user_id with the setting name raw_password

Validated by:

• check_model

field region_name: str | None = None

Validated by:

• check_model

field scan_progress_seconds: int = 10

Validated by:

• check_model

field user_id: str | None = None

The user ID to use

Validated by:

• check_model

field validate_password_on_load: bool = True

Should config_wrangler query the password source for this password at load (startup) time? If so, it will raise an error if the password is None or an empty string. It does not actually connect or authenticate the user_id & password combination.

Validated by:

• check_model

__init__(**data: Any) → None

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

Uses something other than self the first arg to allow “self” as a settable attribute

add_child(name: str, child_object: ConfigHierarchy)

Set this configuration as a child in the hierarchy of another config. For any programmatically created config objects this is required so that the new object ‘knows’ where it lives in the hierarchy – most importantly so that it can find the hierarchies root object.

!!! warning “Deprecated”

This method is now deprecated; use model_copy instead.

If you need include or exclude, use:

• exclude – Optional set or mapping specifying which fields to exclude in the copied model.

• update – Optional dictionary of field-value pairs to override field values in the copied model.

• deep – If True, the values of fields that are Pydantic models will be deep-copied.

Returns:

A copy of the model with included, excluded and updated fields as specified.

Warning

With this method Python code checkers (linters) will not warn about invalid config items. You can end up with runtime AttributeError errors.

get_password() → str

get_ssm()

getboolean(section, item, fallback=Ellipsis) → bool

Validate a pydantic model instance.

Parameters:

• obj – The object to validate.

• strict – Whether to enforce types strictly.

• from_attributes – Whether to extract data from object attributes.

• context – Additional context to pass to the validator.

Raises:

ValidationError – If the object could not be validated.

Returns:

The validated model instance.

classmethod model_validate_json(json_data: str | bytes | bytearray, *, strict: bool | None = None, context: dict[str, Any] | None = None) → Model

Usage docs: https://docs.pydantic.dev/2.6/concepts/json/#json-parsing

Validate the given JSON data against the Pydantic model.

Parameters:

• json_data – The JSON data to validate.

• strict – Whether to enforce types strictly.

• context – Extra variables to pass to the validator.

Returns:

The validated Pydantic model.

Raises:

ValueError – If json_data is not a JSON string.

classmethod model_validate_strings(obj: Any, *, strict: bool | None = None, context: dict[str, Any] | None = None) → Model

Validate the given object contains string data against the Pydantic model.

Parameters:

• obj – The object contains string data to validate.

• strict – Whether to enforce types strictly.

• context – Extra variables to pass to the validator.

Returns:

The validated Pydantic model.

property client: DynamoDBClient

property has_session: bool

model_computed_fields: ClassVar[dict[str, ComputedFieldInfo]] = {}

A dictionary of computed field names and their corresponding ComputedFieldInfo objects.

property model_extra: dict[str, Any] | None

Get extra fields set during validation.

Returns:

A dictionary of extra fields, or None if config.extra is not set to “allow”.

property model_fields_set: set[str]

Returns the set of fields that have been explicitly set on this model instance.

Returns:
