======================= 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. __ https://geoip2.readthedocs.io/ __ https://pypi.org/project/geoip2/ __ https://dev.maxmind.com/geoip/geolite2-free-geolocation-data __ https://github.com/maxmind/libmaxminddb/ Example ======= Here is an example of its usage:: >>> from django.contrib.gis.geoip2 import GeoIP2 >>> g = GeoIP2() >>> g.country('google.com') {'country_code': 'US', 'country_name': 'United States'} >>> g.city('72.14.207.99') {'city': 'Mountain View', 'continent_code': 'NA', 'continent_name': 'North America', 'country_code': 'US', 'country_name': 'United States', 'dma_code': 807, 'is_in_european_union': False, 'latitude': 37.419200897216797, 'longitude': -122.05740356445312, 'postal_code': '94043', 'region': 'CA', 'time_zone': 'America/Los_Angeles'} >>> g.lat_lon('salon.com') (39.0437, -77.4875) >>> g.lon_lat('uh.edu') (-95.4342, 29.834) >>> g.geos('24.124.1.80').wkt 'POINT (-97 38)' 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. =================== ======================================================= Methods ======= Instantiating ------------- .. classmethod:: GeoIP2.open(path, cache) This classmethod instantiates the GeoIP object from the given database path and given cache setting. Querying -------- All the following querying routines may take either a string IP address or a fully qualified domain name (FQDN). For example, both ``'205.186.163.125'`` and ``'djangoproject.com'`` would be valid query parameters. .. method:: GeoIP2.city(query) Returns a dictionary of city information for the given query. Some of the values in the dictionary may be undefined (``None``). .. method:: GeoIP2.country(query) Returns a dictionary with the country code and country for the given query. .. method:: GeoIP2.country_code(query) Returns the country code corresponding to the query. .. method:: GeoIP2.country_name(query) Returns the country name corresponding to the query. Coordinate Retrieval -------------------- .. method:: GeoIP2.coords(query) Returns a coordinate tuple of (longitude, latitude). .. method:: GeoIP2.lon_lat(query) Returns a coordinate tuple of (longitude, latitude). .. method:: GeoIP2.lat_lon(query) Returns a coordinate tuple of (latitude, longitude), .. method:: GeoIP2.geos(query) Returns a :class:`~django.contrib.gis.geos.Point` object corresponding to the query. Settings ======== .. setting:: GEOIP_PATH ``GEOIP_PATH`` -------------- A string or :class:`pathlib.Path` specifying the directory where the GeoIP data files are located. This setting is *required* unless manually specified with ``path`` keyword when initializing the :class:`GeoIP2` object. .. setting:: GEOIP_COUNTRY ``GEOIP_COUNTRY`` ----------------- The basename to use for the GeoIP country data file. Defaults to ``'GeoLite2-Country.mmdb'``. .. setting:: GEOIP_CITY ``GEOIP_CITY`` -------------- The basename to use for the GeoIP city data file. Defaults to ``'GeoLite2-City.mmdb'``. Exceptions ========== .. exception:: GeoIP2Exception The exception raised when an error occurs in a call to the underlying ``geoip2`` library. .. rubric:: Footnotes ..
