version `module-attribute` ¶

SchemaValidator ¶

SchemaValidator is the Python wrapper for pydantic-core's Rust validation logic, internally it owns one CombinedValidator which may in turn own more CombinedValidators which make up the full schema validator.

title `property` ¶

title: str

The title of the schema, as used in the heading of ValidationError.__str__().

validate_python ¶

validate_python(
    input,
    *,
    strict=None,
    from_attributes=None,
    context=None,
    self_instance=None
)

Validate a Python object against the schema and return the validated object.

Parameters:

Name	Type	Description	Default
`input`	`Any`	The Python object to validate.	required
`strict`	`bool \| None`	Whether to validate the object in strict mode. If `None`, the value of `CoreConfig.strict` is used.	`None`
`from_attributes`	`bool \| None`	Whether to validate objects as inputs to models by extracting attributes. If `None`, the value of `CoreConfig.from_attributes` is used.	`None`
`context`	`'dict[str, Any] \| None'`	The context to use for validation, this is passed to functional validators as `info.context`.	`None`
`self_instance`	`Any \| None`	An instance of a model set attributes on from validation, this is used when running validation from the `__init__` method of a model.	`None`

Raises:

Type	Description
`ValidationError`	If validation fails.
`Exception`	Other error types maybe raised if internal errors occur.

Returns:

Type	Description
`Any`	The validated object.

)

Similar to validate_python() but returns a boolean.

Returns:

Type	Description
`bool`	`True` if validation succeeds, `False` if validation fails.

validate_json ¶

validate_json(
    input, *, strict=None, context=None, self_instance=None
)

Validate JSON data directly against the schema and return the validated Python object.

This method should be significantly faster than validate_python(json.loads(json_data)) as it avoids the need to create intermediate Python objects

It also handles constructing the correct Python type even in strict mode, where validate_python(json.loads(json_data)) would fail validation.

Parameters:

Name	Type	Description	Default
`input`	`str \| bytes \| bytearray`	The JSON data to validate.	required

`self_instance`	`Any \| None`	An instance of a model set attributes on from validation.	`None`

Raises:

Type	Description
`ValidationError`	If validation fails or if the JSON data is invalid.
`Exception`	Other error types maybe raised if internal errors occur.

Returns:

Type	Description
`Any`	The validated Python object.

`context`	`'dict[str, Any] \| None'`	The context to use for validation, this is passed to functional validators as `info.context`.	`None`
