FieldMapping Class 
Defines a mapping between a field in a data source and a target field in an index.
All required parameters must be populated in order to send to server.
Constructor
FieldMapping(*, source_field_name: str, target_field_name: str | None = None, mapping_function: _models.FieldMappingFunction | None = None, **kwargs: Any)Keyword-Only Parameters
| Name | Description | 
|---|---|
| source_field_name | The name of the field in the data source. Required. | 
| target_field_name | The name of the target field in the index. Same as the source field name by default. Default value: None | 
| mapping_function | A function to apply to each source field value before indexing. Default value: None | 
Variables
| Name | Description | 
|---|---|
| source_field_name | The name of the field in the data source. Required. | 
| target_field_name | The name of the target field in the index. Same as the source field name by default. | 
| mapping_function | A function to apply to each source field value before indexing. | 
Methods
| as_dict | Return a dict that can be serialized using json.dump. Advanced usage might optionally use a callback as parameter: Key is the attribute name used in Python. Attr_desc is a dict of metadata. Currently contains 'type' with the msrest type and 'key' with the RestAPI encoded key. Value is the current value in this object. The string returned will be used to serialize the key. If the return type is a list, this is considered hierarchical result dict. See the three examples in this file: 
 If you want XML serialization, you can pass the kwargs is_xml=True. | 
| deserialize | Parse a str using the RestAPI syntax and return a model. | 
| enable_additional_properties_sending | |
| from_dict | Parse a dict using given key extractor return a model. By default consider key extractors (rest_key_case_insensitive_extractor, attribute_key_case_insensitive_extractor and last_rest_key_case_insensitive_extractor) | 
| is_xml_model | |
| serialize | Return the JSON that would be sent to server from this model. This is an alias to as_dict(full_restapi_key_transformer, keep_readonly=False). If you want XML serialization, you can pass the kwargs is_xml=True. | 
as_dict
Return a dict that can be serialized using json.dump.
Advanced usage might optionally use a callback as parameter:
Key is the attribute name used in Python. Attr_desc is a dict of metadata. Currently contains 'type' with the msrest type and 'key' with the RestAPI encoded key. Value is the current value in this object.
The string returned will be used to serialize the key. If the return type is a list, this is considered hierarchical result dict.
See the three examples in this file:
- attribute_transformer 
- full_restapi_key_transformer 
- last_restapi_key_transformer 
If you want XML serialization, you can pass the kwargs is_xml=True.
as_dict(keep_readonly: bool = True, key_transformer: ~typing.Callable[[str, dict[str, typing.Any], ~typing.Any], ~typing.Any] = <function attribute_transformer>, **kwargs: ~typing.Any) -> MutableMapping[str, Any]Parameters
| Name | Description | 
|---|---|
| keep_readonly | If you want to serialize the readonly attributes Default value: True | 
| key_transformer | 
				<xref:function>
		 A key transformer function. | 
Returns
| Type | Description | 
|---|---|
| A dict JSON compatible object | 
deserialize
Parse a str using the RestAPI syntax and return a model.
deserialize(data: Any, content_type: str | None = None) -> SelfParameters
| Name | Description | 
|---|---|
| data 
				Required
			 | A str using RestAPI structure. JSON by default. | 
| content_type | JSON by default, set application/xml if XML. Default value: None | 
Returns
| Type | Description | 
|---|---|
| An instance of this model | 
Exceptions
| Type | Description | 
|---|---|
| 
							   DeserializationError 
						 | if something went wrong | 
enable_additional_properties_sending
enable_additional_properties_sending() -> Nonefrom_dict
Parse a dict using given key extractor return a model.
By default consider key extractors (rest_key_case_insensitive_extractor, attribute_key_case_insensitive_extractor and last_rest_key_case_insensitive_extractor)
from_dict(data: Any, key_extractors: Callable[[str, dict[str, Any], Any], Any] | None = None, content_type: str | None = None) -> SelfParameters
| Name | Description | 
|---|---|

				Required
			 | A dict using RestAPI structure | 
| key_extractors | 
				<xref:function>
		 A key extractor function. Default value: None | 
| content_type | JSON by default, set application/xml if XML. Default value: None | 
Returns

is_xml_model
is_xml_model() -> boolserialize
Return the JSON that would be sent to server from this model.
This is an alias to as_dict(full_restapi_key_transformer, keep_readonly=False).
If you want XML serialization, you can pass the kwargs is_xml=True.
serialize(keep_readonly: bool = False, **kwargs: Any) -> MutableMapping[str, Any]Parameters
| Name | Description | 
|---|---|
| keep_readonly | If you want to serialize the readonly attributes Default value: False | 
Returns
| Type | Description | 
|---|---|
| A dict JSON compatible object |
