Additional functionality using the GeoIP2 database.

Project description

https://badge.fury.io/py/django-geoip2-extras.svg https://travis-ci.org/yunojuno/django-geoip2-extras.svg

The master branch of this project is now Python3 only. Python2 support is restricted to the python2 branch.

Django GeoIP2 Extras

Useful extras based on the django.contrib.gis.geoip2 module, using the MaxMind GeoIP2 Lite database.

The first feature in this package is a Django middleware class that can be used to add city, country level information to inbound requests.

Requirements

This package wraps the existing Django functionality, and as a result relies on the same underlying requirements:

In order to perform IP-based geolocation, the GeoIP2 object requires the geoip2 Python library and the GeoIP Country and/or City datasets in binary format (the CSV files will not work!). Grab the GeoLite2-Country.mmdb.gz and GeoLite2-City.mmdb.gz files and unzip them in a directory corresponding to the GEOIP_PATH setting.

In addition, the middleware follows the ‘new’ middleware pattern, and therefore does not support Django 1.9 or below. This is a 1.10 and above package.

Installation

This package can be installed from PyPI as django-geoip2-extras:

$ pip install django-geoip2-extras

If you want to add the country-level information to incoming requests, add the middleware to your project settings. NB The GeoIP2Middleware relies on the SessionMiddleware, and must come after it:

MIDDLEWARE = (
    ...,
    'django.contrib.sessions.middleware.SessionMiddleware',
    'geoip2_extras.middleware.GeoIP2Middleware',
    ...
)

The middleware will not be active unless you add a setting for the default GEOIP_PATH - this is the default Django GeoIP2 behaviour:

# settings.py
GEOIP_PATH = os.path.dirname(__file__)

NB Loading this package does not install the MaxMind database. That is your responsibility. The Country database is 2.7MB, and could be added to most project comfortably, but it is updated regularly, and keeping that up-to-date is out of scope for this project. The City database is 27MB, and is probably not suitable for adding to source control. There are various solutions out on the web for pulling in the City database as part of a CD process.

Usage

Once the middleware is added, you will be able to access City and / or Country level information on the request object:

>>> request.geo_data.ip_address
'1.2.3.4'
>>> request.geo_data.city
'Beverley Hills'
>>> request.geo_data.postal_code
'90210'
>>> request.geo_data.region
'California'
>>> request.geo_data.country_code
'US'
>>> request.geo_data.country_name
'United States'
>>> request.geo_data.latitude
'34.0736'
>>> request.geo_data.longitude
'118.4004'

Missing / incomplete data will be None.

If the IP address cannot be found (e.g. ‘127.0.0.1’), then a default ‘unknown’ country is used, with a code of ‘XX’:

>>> geo.ip_address
'127.0.0.1'
>>> geo.country_code
'XX'
>>> geo.country_name
'unknown'
>>> geo.is_unknown
True

This prevents the middleware from re-requesting the address on each request - it effectively marks the IP as a bad address.

Tests

The project tests are run through tox.
