Static methods

construct

def construct(
    _fields_set: 'set[str] | None' = None,
    **values: 'Any'
) -> 'Self'

from_orm

def from_orm(
    obj: 'Any'
) -> 'Self'

model_construct

def model_construct(
    _fields_set: 'set[str] | None' = None,
    **values: 'Any'
) -> 'Self'

Creates a new instance of the Model class with validated data.

Creates a new model setting __dict__ and __pydantic_fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed.

Note

model_construct() generally respects the model_config.extra setting on the provided model. That is, if model_config.extra == 'allow', then all extra passed values are added to the model instance's __dict__ and __pydantic_extra__ fields. If model_config.extra == 'ignore' (the default), then all extra passed values are ignored. Because no validation is performed with a call to model_construct(), having model_config.extra == 'forbid' does not result in an error if extra values are passed, but they will be ignored.

Parameters:

Name	Type	Description	Default
_fields_set	None	A set of field names that were originally explicitly set during instantiation. If provided, this is directly used for the [model_fields_set][pydantic.BaseModel.model_fields_set] attribute. Otherwise, the field names from the values argument will be used.	None
values	None	Trusted or pre-validated data dictionary.	None

Returns:

Type	Description

Usage docs: docs.pydantic.dev/2.10/concepts/serialization/#modelmodel_dump_json

Generates a JSON representation of the model using Pydantic's to_json method.

Parameters:

Name	Type	Description	Default
indent	None	Indentation to use in the JSON output. If None is passed, the output will be compact.	None
include	None	Field(s) to include in the JSON output.	None
exclude	None	Field(s) to exclude from the JSON output.	None
context	None	Additional context to pass to the serializer.	None
by_alias	None	Whether to serialize using field aliases.	None
exclude_unset	None	Whether to exclude fields that have not been explicitly set.	None
exclude_defaults	None	Whether to exclude fields that are set to their default value.	None
exclude_none	None	Whether to exclude fields that have a value of None.	None
round_trip	None	If True, dumped values should be valid as input for non-idempotent types such as Json[T].	None
warnings	None	How to handle serialization errors. False/"none" ignores them, True/"warn" logs errors, "error" raises a [PydanticSerializationError][pydantic_core.PydanticSerializationError].	None
serialize_as_any	None	Whether to serialize fields with duck-typing serialization behavior.	None

Returns:

Type	Description
None	A JSON string representation of the model.

model_post_init

def model_post_init(
    self,
    _BaseModel__context: 'Any'
) -> 'None'

Override this method to perform additional initialization after __init__ and model_construct.

This is useful if you want to do some validation that requires the entire model to be initialized.
