Returns:

A dict containing values from the object

ironic.api.controllers.v1.utils.patch_update_changed_fields(from_dict, rpc_object, fields, schema, id_map=None)

Update rpc object based on changed fields in a dict.

Only fields which have a corresponding schema field are updated when changed. Other values can be updated using the id_map.

Parameters:

• from_dict – Dict containing changed field values

• rpc_object – Object to update changed fields on

• fields – Field names on the rpc object

• schema – jsonschema to get field names of the dict

• id_map – Optional dict mapping object field names to arbitrary values when there is no matching field in the schema

ironic.api.controllers.v1.utils.patch_validate_allowed_fields(patch, allowed_fields)

Validate that a patch list only modifies allowed fields.

Parameters:

• patch – List of patch dicts to validate

• allowed_fields – List of fields which are allowed to be patched

Returns:

The list of fields which will be patched

Raises:

exception.Invalid if any patch changes a field not in allowed_fields

ironic.api.controllers.v1.utils.patched_validate_with_schema(patched_dict, schema, validator=None)

Validate a patched dict object against a validator or schema.

This function has the side-effect of deleting any dict value which is not in the schema. This allows database-loaded objects to be pruned of their internal values before validation.

Parameters:

• patched_dict – dict representation of the object with patch updates applied

• schema – Any dict key not in the schema will be deleted from the dict. If no validator is specified then the resulting patched_dict will be validated against the schema

• validator – Optional validator to use if there is extra validation required beyond the schema

Raises:

exception.Invalid if validation fails

ironic.api.controllers.v1.utils.populate_node_uuid(obj, to_dict)

Look up the node referenced in the object and populate a dict.

The node is fetched with the object node_id attribute and the dict node_uuid value is populated with the node uuid

Parameters:

• obj – object to get the node_id attribute

• to_dict – dict to populate with a node_uuid value

Raises:

exception.NodeNotFound if the node is not found

ironic.api.controllers.v1.utils.replace_node_id_with_uuid(to_dict)

Replace node_id dict value with node_uuid

node_uuid is found by fetching the node by id lookup.

Parameters:

to_dict – Dict to set node_uuid value on

Returns:

The node object from the lookup

Raises:

NodeNotFound with status_code set to 400 BAD_REQUEST when node is not found.

ironic.api.controllers.v1.utils.replace_node_uuid_with_id(to_dict)

Replace node_uuid dict value with node_id

node_id is found by fetching the node by uuid lookup.

Parameters:

to_dict – Dict to set node_id value on

Returns:

The node object from the lookup

Raises:

NodeNotFound with status_code set to 400 BAD_REQUEST when node is not found.

ironic.api.controllers.v1.utils.sanitize_dict(to_sanitize, fields)

Removes sensitive and unrequested data.

Will only keep the fields specified in the fields parameter (plus the links field).

Parameters:

• to_sanitize – dict to sanitize

• fields (list of str) – list of fields to preserve, or None to preserve them all

ironic.api.controllers.v1.utils.validate_limit(limit)

ironic.api.controllers.v1.utils.validate_sort_dir(sort_dir)

ironic.api.controllers.v1.utils.vendor_passthru(ident, method, topic, data=None, driver_passthru=False)

Call a vendor passthru API extension.

Call the vendor passthru API extension and process the method response to set the right return code for methods that are asynchronous or synchronous; Attach the return value to the response object if it’s being served statically.

Parameters:

• ident – The resource identification. For node’s vendor passthru this is the node’s UUID, for driver’s vendor passthru this is the driver’s name.

• method – The vendor method name.

• topic – The RPC topic.

• data – The data passed to the vendor method. Defaults to None.

• driver_passthru – Boolean value. Whether this is a node or driver vendor passthru. Defaults to False.

Returns:

A WSME response object to be returned by the API.
