Django Ip Geolocation

Django request/response hooks to geolocate visitors by their ip address.

Installing

python -m pip install django-ip-geolocation

Usage

Decorator

Use decorators to decorate views:

from django_ip_geolocation.decorators import with_ip_geolocation

@with_ip_geolocation
def api_view(request):
   location = request.geolocation
   ...

Middleware

First you need to add the middleware into your settings.py.

MIDDLEWARE = [
    ...
    'django_ip_geolocation.middleware.IpGeolocationMiddleware',
    ...
]

Then the location is available to all views in request and response:

def api_view(request):
   location = request.geolocation
   ...
   
def other_view(request):
  location = request.geolocation
  ...

Cookie

Geolocation data stored in the Response cookie lacks the raw_data and is base64 encoded.

User consent

Developers must implement a helper function to check if the user consented or not and configure it in the settings.py.

By default if the developer didn't provide a validation function, we consider it as implicit consent.

Here is an example of the helper function:

def check_user_consent(request):
  if request.user.is_consented: # this is only an example.
    return True
  return False

Settings

You can configure settings for your hook in the settings.py as follow:

IP_GEOLOCATION_SETTINGS = {
    'BACKEND': 'django_ip_geolocation.backends.IPGeolocationAPI',
    'BACKEND_API_KEY': '',
    'BACKEND_EXTRA_PARAMS': {},
    'BACKEND_USERNAME': '',
    'RESPONSE_HEADER': 'X-IP-Geolocation',
    'ENABLE_REQUEST_HOOK': True,
    'ENABLE_RESPONSE_HOOK': True,
    'ENABLE_COOKIE': False,
    'FORCE_IP_ADDR': None,
    'USER_CONSENT_VALIDATOR': None
}

Those are the default settings, that will be overwritten by those set in settings.py

setting	description	default value (type)
`BACKEND`	Backend class used to detect the geolocation	`django_ip_geolocation.backends.IPGeolocationAPI` (string class path)
`BACKEND_API_KEY`	Api key or token for the backend	Empty (string)
`BACKEND_EXTRA_PARAMS`	Extra parameters specific to the backend	`{}` (dict)
`BACKEND_USERNAME`	username for the backend	Empty (string)
`RESPONSE_HEADER`	Custom response header to store the geolocation	`X-IP-Geolocation` (string)
`ENABLE_REQUEST_HOOK`	Enable or disable hook on request	`True` (bool)
`ENABLE_RESPONSE_HOOK`	Enable or disable hook on request	`True` (bool)
`ENABLE_COOKIE`	Enable or disable geolocation data in cookie	`False` (bool)
`FORCE_IP_ADDR`	Force ip address, rather than using visitor ip	`None` (string)
`USER_CONSENT_VALIDATOR`	A function path to check if the current user gave his consent	`None` (string, function path)

Implementing your own backend

If you want to add a new backend, you need to inherit from django_ip_geolocation.backends.base, then you need to implement geolocate() and _parse().

`geolocate()`

Makes API calls and stores the API response in self._raw_data.

`_parse()`

Parse raw data stored in self._raw_data and assigns values to the class attribute, such as self._continent, self._county, self._geo.

self._country is a dict with code and name keys.

self._geo is a dict with latitude and longitude keys.
