`calculate_instance_name_from_dict`(data[, ...])	Convert the provided keyword arguments to an instance name.
`model_post_init`(context)

Attributes

`model_config`	Configuration for the model, should be a dictionary conforming to `ConfigDict`.

classmethod by_instrument(instrument: __annotationlib_name_1__ | Uid) → Self | None[source]

Return the ledger instance associated with the given instrument.

If no ledger exists for the instrument, returns None.

classmethod calculate_instance_name_from_dict(data: Mapping[str, Any], allow_missing_instrument: bool = False) → str[source]

Convert the provided keyword arguments to an instance name.

This method should be implemented by subclasses to define how to derive the instance name.

Parameters:

Return type:

str

model_config: ClassVar[ConfigDict] = {'extra': 'allow', 'frozen': True, 'serialize_by_alias': True, 'validate_assignment': True, 'validate_by_alias': True}: Configuration for the model, should be a dictionary conforming to ConfigDict.
