Documentation
=============

Available on readthedocs_.

.. _readthedocs: http://neomodel.readthedocs.org

Requirements
============

- Python 2.7, 3.3+
- neo4j 3.0, 3.1, 3.2

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'.
