Django integration for geocoding (using Geocodio)

Project Description

Django features for simple geocoding. Current support for the Geocodio geocoding service

Read the full docs on Read the Docs.

Installing

Install dj-geocoding:

pip install dj-geocoding

Then use it in a project:

import dj-geocoding

Add your geocoding service API credentials to your settings.py file:

GEOCODIO_API_KEY="SOMEAPIKEY"

Model

Use the optional model mixin to your model if you aren’t using PostGIS:

from dj_geocoding.models import GeoBase

class MyModel(GeoBase, models.Model):
    pass

This adds the followng fields:

latitude = models.DecimalField(decimal_places=15, max_digits=18, null=True,
        blank=True)
longitude = models.DecimalField(decimal_places=15, max_digits=18, null=True,
        blank=True)

Adds a geocode method:

def geocode(self, \*args, \**kwargs):
    return geocode()

You should extend this in your model, providing the field(s) from which the address will be pulled:

def geocode(self):
    return super(MyModel, self).geocode('address')

You can choose the separator for providing a single address, too:

def geocode(self):
    return super(MyModel, self).geocode('street_address', 'city', 'state',
            seperator=", ")

And additional property attributes for the point attribute.

Bulk geocoding

The bulk_geocode function takes a queryset and geocodes its member objects.

Note

The model must implement a point-type field that behaves like a Point field.

Example:

geocoded_qs = bulk_geocode(MyModel.objects.all())

Specifying the field name:

geocoded_qs = bulk_geocode(MyModel.objects.all(), field='point')

Manager

The manager class implements a subclassed QuerySet with a geocode method:

MyModel.objects.all().geocode()

This returns a queryset of the objects updated (or not) that fit within the limits of the geocoding service. It is a convenient interface tot he bulk_geocode function.

Admin site

The GeocodedFilter filter can be used to filter locations in the admin based on whether they have been geolocated or not.

The GeolocateMixin class can be added to your ModelAdmin definition to add the geocode_address admin action. This adds the “geocode address” action to the admin actions dropdown menu and then will allow you to geocode an entire queryset from the admin.
