Deprecated since version 0.1.0: Use Run instead. It will not be removed until langchain-core==1.0.

Base class for Run.

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.

Attributes

uuid

UUID objects (universally unique identifiers) according to RFC 4122.

Methods

__init__(**data)

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

construct([_fields_set])

Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data.

copy(*[, include, exclude, update, deep])

Duplicate a model, optionally choose which fields to include, exclude and change.

dict(*[, include, exclude, by_alias, ...])

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

from_orm(obj)

json(*[, include, exclude, by_alias, ...])

Generate a JSON representation of the model, include and exclude arguments as per dict().

parse_file(path, *[, content_type, ...])

parse_obj(obj)

parse_raw(b, *[, content_type, encoding, ...])

schema([by_alias, ref_template])

schema_json(*[, by_alias, ref_template])

update_forward_refs(**localns)

Try to update ForwardRefs on fields based on this Model, globalns and localns.

validate(value)

Parameters:
  • uuid (str)

  • parent_uuid (str | None)

  • start_time (datetime)

  • end_time (datetime)

  • extra (dict[str, Any] | None)

  • execution_order (int)

  • child_execution_order (int)

  • serialized (dict[str, Any])

  • session_id (int)

  • error (str | None)

__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.

Parameters:

data (Any)

Return type:

None

classmethod construct(
_fields_set: SetStr | None = None,
**values: Any,
) Model#

Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed. Behaves as if Config.extra = ‘allow’ was set since it adds all passed values

Parameters:
  • _fields_set (SetStr | None)

  • values (Any)

Return type:

Model

copy(
*,
include: AbstractSetIntStr | MappingIntStrAny | None = None,
exclude: AbstractSetIntStr | MappingIntStrAny | None = None,
update: DictStrAny | None = None,
deep: bool = False,
) Model#

Duplicate a model, optionally choose which fields to include, exclude and change.

Parameters:
  • include (AbstractSetIntStr | MappingIntStrAny | None) – fields to include in new model

  • exclude (AbstractSetIntStr | MappingIntStrAny | None) – fields to exclude from new model, as with values this takes precedence over include

  • update (DictStrAny | None) – values to change/add in the new model. Note: the data is not validated before creating the new model: you should trust this data

  • deep (bool) – set to True to make a deep copy of the model

  • self (Model)

Returns:

new model instance

Return type:

Model

dict(
*,
include: AbstractSetIntStr | MappingIntStrAny | None = None,

exclude_defaults: bool = False,
exclude_none: bool = False,
) DictStrAny#

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

Parameters:
