Additional functionality using the GeoIP2 database.

Project description

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 requires Django 2.2 or above, and Python 3.7 or above.

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.

NB The MaxMind database is not included with this package. It is your responsiblity to download this and include it as part of your project.

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.

# settings.py
MIDDLEWARE = (
    ...,
    '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__)

You must also configure a cache called geoip2-extras:

# settings
CACHES = {
    "default": { ... },
    "geoip2-extras": { ... },
    ...
}

Tip: see /demo/settings.py for a full working example.

Settings

The following settings can be overridden in django.conf.settings.

  • GEOIP2_EXTRAS_CACHE_TIMEOUT

Time to cache IP <> address data in seconds - default to 1hr (3600s)

  • GEOIP2_EXTRAS_ADD_RESPONSE_HEADERS

Set to True to write out the GeoIP data to the response headers. Defaults to use the DEBUG value. This value can be overridden on a per-request basis by adding the X-GeoIP2-Debug request header, or adding geoip2=1 to the request querystring. This is useful for debugging in a production environment where you may not be adding the response headers by default.

Usage

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

>>> request.geo_data
{
    "city": ""
    "continent-code": "NA"
    "continent-name": "North America"
    "country-code": "US"
    "country-name": "United States"
    "dma-code": ""
    "is-in-european-union": False
    "latitude": 37.751
    "longitude": -97.822
    "postal-code": ""
    "region": ""
    "time-zone": "America/Chicago"
    "remote-addr": "142.250.180.3"
}

The same information will be added to the HttpResponse headers if GEOIP2_EXTRAS_ADD_RESPONSE_HEADERS is True. Values are set using the X-GeoIP2- prefix.

NB blank ("") values are not added to the response:

# use the google.co.uk IP
$ curl -I -H "x-forwarded-for: 142.250.180.3" localhost:8000
HTTP/1.1 200 OK
Date: Sun, 29 Aug 2021 15:47:22 GMT
Server: WSGIServer/0.2 CPython/3.9.4
Content-Type: text/html
X-GeoIP2-Continent-Code: NA
X-GeoIP2-Continent-Name: North America
X-GeoIP2-Country-Code: US
X-GeoIP2-Country-Name: United States
X-GeoIP2-Is-In-European-Union: False
X-GeoIP2-Latitude: 37.751
X-GeoIP2-Longitude: -97.822
X-GeoIP2-Time-Zone: America/Chicago
X-GeoIP2-Remote-Addr: 142.250.180.3
Content-Length: 10697

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'.

$ curl -I -H "x-forwarded-for: 127.0.0.1" localhost:8000
HTTP/1.1 200 OK
Date: Sun, 29 Aug 2021 15:47:22 GMT
Server: WSGIServer/0.2 CPython/3.9.4
Content-Type: text/html
X-GeoIP2-Country-Code: XX
X-GeoIP2-Country-Name: unknown
X-GeoIP2-Remote-Addr: 127.0.0.1
Content-Length: 10697

Tests

The project tests are run through pytest.
