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
None A new instance of the Model class with validated data.

model_json_schema

def model_json_schema(
    by_alias: 'bool' = True,

    schema_generator: 'type[GenerateJsonSchema]' = <class 'pydantic.json_schema.GenerateJsonSchema'>,
    mode: 'JsonSchemaMode' = 'validation'
) -> 'dict[str, Any]'

Generates a JSON schema for a model class.

Parameters:

Name Type Description Default
by_alias None Whether to use attribute aliases or not. None
ref_template None The reference template. None
schema_generator None To override the logic used to generate the JSON schema, as a subclass of
GenerateJsonSchema with your desired modifications

model_parametrized_name

def model_parametrized_name(

This method can be overridden to achieve a custom naming scheme for generic BaseModels.

Parameters:

Model with 2 type variables and a concrete model Model[str, int],
the value (str, int) would be passed to params.

Returns:

Type Description

Raises:

Type Description
TypeError Raised when trying to generate concrete names for non-generic models.

) -> 'bool | None'

raise_errors None Whether to raise errors, defaults to True. None
_parent_namespace_depth None The depth level of the parent namespace, defaults to 2. None

Returns:

Type Description
None Returns None if the schema is already "complete" and rebuilding was not required.
If rebuilding was required, returns True if rebuilding was successful, otherwise False.
