Geolocation with GeoIP2
|
|
=======================
|
|
|
|
.. module:: django.contrib.gis.geoip2
|
|
:synopsis: Python interface for MaxMind's GeoIP2 databases.
|
|
|
|
The :class:`GeoIP2` object is a wrapper for the `MaxMind geoip2 Python
|
|
library`__. [#]_
|
|
|
|
In order to perform IP-based geolocation, the :class:`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 :setting:`GEOIP_PATH` setting.
|
|
|
|
Additionally, it is recommended to install the `libmaxminddb C library`__, so
|
|
that ``geoip2`` can leverage the C library's faster speed.

API Reference
|
|
=============
|
|
|
|
.. class:: GeoIP2(path=None, cache=0, country=None, city=None)
|
|
|
|
The ``GeoIP`` object does not require any parameters to use the default
|
|
settings. However, at the very least the :setting:`GEOIP_PATH` setting
|
|
should be set with the path of the location of your GeoIP datasets. The
|
|
following initialization keywords may be used to customize any of the
|
|
defaults.
|
|
|
|
=================== =======================================================
|
|
Keyword Arguments Description
|
|
=================== =======================================================
|
|
``path`` Base directory to where GeoIP data is located or the
|
|
full path to where the city or country data files
|
|
(``.mmdb``) are located. Assumes that both the city and
|
|
country datasets are located in this directory;
|
|
overrides the :setting:`GEOIP_PATH` setting.
|
|
|
|
``cache`` The cache settings when opening up the GeoIP datasets. May
|
|
be an integer in (0, 1, 2, 4, 8) corresponding to the
|
|
``MODE_AUTO``, ``MODE_MMAP_EXT``, ``MODE_MMAP``, and
|
|
``GEOIP_INDEX_CACHE`` ``MODE_MEMORY`` C API settings,
|
|
respectively. Defaults to 0 (``MODE_AUTO``).
|
|
|
|
``country`` The name of the GeoIP country data file. Defaults
|
|
to ``GeoLite2-Country.mmdb``. Setting this keyword
|
|
overrides the :setting:`GEOIP_COUNTRY` setting.
|
|
|
|
``city`` The name of the GeoIP city data file. Defaults to
|
|
``GeoLite2-City.mmdb``. Setting this keyword overrides
|
|
the :setting:`GEOIP_CITY` setting.
