A Flask extension that provides simple interaction with the Neo4j graph database.

These capabilities are made possible by the fine library: py2neo

Using pip:

pip install flask-neo4j

Typical usage looks like this:

from flask import Flask
from flask.ext.neo4j import Neo4j
from py2neo import neo4j

app = Flask(__name__)
graph_indexes = {'Species': neo4j.Node}
flask4j = Neo4j(app, graph_indexes)
print flask4j.gdb.neo4j_version
nosferatu = flask4j.index['Species'].get_or_create('species_id', 1234,
    {   'full_name': 'Dracula nosferatu',
        'species_name': 'nosferatu',
        'type': 'species'
    }
)

full_path = nosferatu.get_or_create_path(
    'MEMBER_OF', { 'name': 'Dracula', 'type': 'genus' },
)

# which all results in a graph that looks like:
#  (species)-[:MEMBER_OF]->(genus)
