An Object Graph Mapper (OGM) for the neo4j graph database, built on the awesome neo4j_driver
Familiar Django model style definitions.
Powerful query API.
Enforce your schema through cardinality restrictions.
Full transaction support.
Thread safe.
Hooks including (optional) Django signals support.
Documentation
Available on readthedocs.
Requirements
Python 2.7, 3.3, 3.4 + 3.5
neo4j 3.0+
Installation
Install from pypi (recommended):
$ pip install neomodel
To install from github:
$ pip install git+git://github.com/robinedwards/neomodel.git@HEAD#egg=neomodel-dev
Upgrading 2.x to 3.x
Now utilises neo4j_driver as the backend which uses bolt so neo4j 3 is required
Connection now set through config.DATABASE_URL (see getting started docs)
The deprecated category() method on StructuredNode has been removed
The deprecated index property on StructuredNode has been removed
The streaming=True flag is now irrelevant with bolt and produces a deprecation warning
Batch operations must now be wrapped in a transaction in order to be atomic
Indexing NodeSets returns a single node now as opposed to a list
Contributing
Ideas, bugs, tests and pull requests always welcome.
Running the test suite
Make sure you have a fresh virtualenv and nose installed:
$ pip install nose
Also a Neo4j database version 3 or higher to run the tests on. (it will wipe this database for each test run):
$ export NEO4J_BOLT_URL=bolt://neo4j:neo4j@localhost:7687 # (the default)
Setup a virtual environment, install neomodel for development and run the test suite:
$ virtualenv venv $ source venv/bin/activate $ python setup.py develop $ nosetests -s
If your running a neo4j database for the first time the test suite will set the password to ‘test’.
