Geolocation with GeoIP
|
|
======================
|
|
|
|
.. module:: django.contrib.gis.geoip
|
|
:synopsis: High-level Python interface for MaxMind's GeoIP C library.
|
|
|
|
.. deprecated:: 1.9
|
|
|
|
This module is deprecated in favor of :doc:`django.contrib.gis.geoip2
|
|
</ref/contrib/gis/geoip2>`, which supports IPv6 and the GeoLite2 database
|
|
format.
|
|
|
|
The :class:`GeoIP` object is a ctypes wrapper for the
|
|
`MaxMind GeoIP C API`__. [#]_
|
|
|
|
In order to perform IP-based geolocation, the :class:`GeoIP` object requires
|
|
the GeoIP C library and either the GeoIP `Country`__ or `City`__
|
|
datasets in binary format (the CSV files will not work!). These datasets may be
|
|
`downloaded from MaxMind`__. Grab the ``GeoLiteCountry/GeoIP.dat.gz`` and
|
|
``GeoLiteCity.dat.gz`` files and unzip them in a directory corresponding to what
|
|
you set :setting:`GEOIP_PATH` with in your settings. See the example and
|
|
reference below for more details.

Example
|
|
=======
|
|
|
|
Assuming you have the GeoIP C library installed, here is an example of its
|
|
usage::
|
|
|
|
>>> from django.contrib.gis.geoip import GeoIP
|
|
>>> g = GeoIP()
|
|
>>> g.country('google.com')
|
|
{'country_code': 'US', 'country_name': 'United States'}
|
|
>>> g.city('72.14.207.99')
|
|
{'area_code': 650,
|
|
'city': 'Mountain View',
|
|
'country_code': 'US',
|
|
'country_code3': 'USA',
|
|
'country_name': 'United States',
|
|
'dma_code': 807,
|
|
'latitude': 37.419200897216797,
|
|
'longitude': -122.05740356445312,
|
|
'postal_code': '94043',
|
|
'region': 'CA'}
|
|
>>> g.lat_lon('salon.com')
|
|
(37.789798736572266, -122.39420318603516)
|
|
>>> g.lon_lat('uh.edu')
|
|
(-95.415199279785156, 29.77549934387207)
|
|
>>> g.geos('24.124.1.80').wkt
|
|
'POINT (-95.2087020874023438 39.0392990112304688)'

``GeoIP`` Settings
|
|
==================
|
|
|
|
.. setting:: GEOIP_PATH
|
|
|
|
GEOIP_PATH
|
|
----------
|
|
|
|
A string specifying the directory where the GeoIP data files are
|
|
located. This setting is *required* unless manually specified
|
|
with ``path`` keyword when initializing the :class:`GeoIP` object.
|
|
|
|
.. setting:: GEOIP_LIBRARY_PATH
|
|
|
|
GEOIP_LIBRARY_PATH
|
|
------------------
|
|
|
|
A string specifying the location of the GeoIP C library. Typically,
|
|
this setting is only used if the GeoIP C library is in a non-standard
|
|
location (e.g., ``/home/sue/lib/libGeoIP.so``).
|
|
|
|
.. setting:: GEOIP_COUNTRY
|
|
|
|
GEOIP_COUNTRY
|
|
-------------
|
|
|
|
The basename to use for the GeoIP country data file.
|
|
Defaults to ``'GeoIP.dat'``.
|
|
|
|
.. setting:: GEOIP_CITY
|
|
|
|
GEOIP_CITY
|
|
----------
|
|
|
|
The basename to use for the GeoIP city data file.
|
|
Defaults to ``'GeoLiteCity.dat'``.
|
|
|
|
``GeoIP`` API
|
|
=============
|
|
|
|
.. class:: GeoIP(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 data sets. 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
|
|
(.dat) are located. Assumes that both the city and
|
|
country data sets are located in this directory;
|
|
overrides the :setting:`GEOIP_PATH` settings attribute.
|
|
|
|
``cache`` The cache settings when opening up the GeoIP datasets,
|
|
and may be an integer in (0, 1, 2, 4) corresponding to
|
|
the ``GEOIP_STANDARD``, ``GEOIP_MEMORY_CACHE``,
|
|
``GEOIP_CHECK_CACHE``, and ``GEOIP_INDEX_CACHE``
|
|
``GeoIPOptions`` C API settings, respectively.
|
|
Defaults to 0 (``GEOIP_STANDARD``).
|
|
|
|
``country`` The name of the GeoIP country data file. Defaults
|
|
to ``GeoIP.dat``. Setting this keyword overrides the
|
|
:setting:`GEOIP_COUNTRY` settings attribute.
|
|
|
|
``city`` The name of the GeoIP city data file. Defaults to
|
|
``GeoLiteCity.dat``. Setting this keyword overrides
|
|
the :setting:`GEOIP_CITY` settings attribute.
|
|

|
|
parameters.
