A quick example using neo4django with tastypie adapted from the tastypie tutorial (http://django-tastypie.readthedocs.org/en/latest/tutorial.html).
from tastypie.resources import ModelResource
from .models import Entry
class EntryResource(ModelResource):
class Meta:
queryset = Entry.objects.all()
resource_name = 'entry'

Some relationship magic to make modeling easier for situations where you want to aggregate across multiple rel-types in one relationship field. This is a very not-supported / non-standard approach, and could be broken in future versions of neo4django.
>>> from .models import Family, Person
>>>
>>> family_1 = Family.objects.create(status='married')
>>> family_2 = Family.objects.create()
>>>
>>> pete = Person.objects.create(name='Pete')
>>> mary = Person.objects.create(name='Mary')
>>>
>>> family_1.spouses.add(pete, mary)
>>> family_2.children.add(pete)

A quick bit of Cypher demonstrating how you can change the default null-ordering in ORDER BY. Note that the trick is in the null predicate and STR cast.
START n=node({startId})
MATCH (n)-[?:DID]->(thing)
WITH thing, (thing.year? = null) AS year_is_null
WITH thing, STR(year_is_null) as null_year
ORDER BY null_year, thing.year? DESC
RETURN thing, thing.year? as year
