This adds simple support for retrieving missing data from a neo4j instance.
Given this setup:
class Author: def __init__(self, _id, name, organization): self._id = _id self.name = name class Book: def __init__(self, _id, name, author): self._id = _id self.name = name self.author = author class AuthorSchema(JsonLDSchema): """Author schema.""" name = fields.String(schema.name) _id = fields.Id() class Meta: """Meta class.""" rdf_type = schema.Person model = Author class BookSchema(JsonLDSchema): _id = fields.Id() name = fields.String(schema.name) author = fields.Nested(schema.author, AuthorSchema, missing=None) class Meta: rdf_type = schema.Book model = Book
One can retrieve the data for a single book with
from calamus.backends.neo4j import CalamusNeo4JBackend neo = CalamusNeo4JBackend() neo.initialize() data = neo.fetch_by_id('http://example.com/books/1')
The full data, including the author information can then be obtained with
book = BookSchema(session=neo).load(data)
