deleteAttribute

This method causes the specified attribute value (the value at the 'address' of a specific Object Class and ID and an Attribute Type ID) to be 'unset' or deleted. Subsequent calls to getAttribute() with the same parameters would then return None.

PARAMETERS

Param 1: object_type -- (string) must be in the list of valid Object Types as returned by getAttributeObjectTypes.

Param 2: object_id -- (string) the Journyx database ID of the Object that we are deleting an attribute value for. It should belong to the object class (table) indicated by the first parameter.

Param 3: id_attr_type -- (string) the ID of the Attribute Type that we are to delete the values of.

RETURN VALUE / EXCEPTIONS

If deleting the attribute value was successful, then None is returned, otherwise an exception is raised in these circumstances:

• Object Type is invalid (RuntimeError)

• The Object ID does not exist (ValueError)

• The Attribute Type ID does not exist (ValueError)

• The Attribute Value cannot be deleted (due to a permissions error or other reasons)

If the Object ID and Attribute Type ID were valid, but no value was previously set, then None is returned (no exception is raised.)

Arguments

Return

The deleteAttribute method returns zero (an integer).
