Django Address
Django models for storing and retrieving postal addresses.

Overview
Django Address is a set of models and methods for working with postal addresses.
Requirements

Python (3.5, 3.6, 3.7, 3.8)
Django (2.2, 3.0)

We recommend and only officially support the latest patch release of each Python and Django series.
Installation
For more detailed instructions, view the Readme for the example site included with this package.
pip install django-address

Then, add address to your INSTALLED_APPS list in settings.py:
INSTALLED_APPS = [
# ...
'address',
# ...
]

You can either store your Google API key in an environment variable as GOOGLE_API_KEY or you can
specify the key in settings.py. If you have an environment variable set it will override what you put in settings.py.
For more information, including enabling the Google Places API, refer to the example site.
GOOGLE_API_KEY = 'AIzaSyD--your-google-maps-key-SjQBE'

The Model
The rationale behind the model structure is centered on trying to make
it easy to enter addresses that may be poorly defined. The model field included
uses Google Maps API v3 (via the nicely done geocomplete jquery plugin) to
determine a proper address where possible. However if this isn't possible the
raw address is used and the user is responsible for breaking the address down
into components.
It's currently assumed any address is represent-able using four components:
country, state, locality and street address. In addition, country code, state
code and postal code may be stored, if they exist.
There are four Django models used:
Country
name
code

State
name
code
country -> Country

Locality
name
postal_code
state -> State

Address
raw
street_number
route
locality -> Locality

Address Field
To simplify storage and access of addresses, a subclass of ForeignKey named
AddressField has been created. It provides an easy method for setting new
addresses.
ON_DELETE behavior of Address Field
By default, if you delete an Address that is related to another object,
Django's cascade behavior
is used. This means the related object will also be deleted. You may also choose
to set null=True when defining an address field to have the address set
to Null instead of deleting the related object. For more information and an example,
see the readme for the django-address example_site.
Creation
It can be created using the same optional arguments as a ForeignKey field.
For example:
from address.models import AddressField

class MyModel(models.Model):
address1 = AddressField()
address2 = AddressField(related_name='+', blank=True, null=True)

Setting Values
Values can be set either by assigning an Address object:
addr = Address(...)
addr.save()
obj.address = addr

Or by supplying a dictionary of address components:
obj.address = {'street_number': '1', 'route': 'Somewhere Ave', ...}

The structure of the address components is as follows:
{
'raw': '1 Somewhere Ave, Northcote, VIC 3070, AU',
'street_number': '1',
'route': 'Somewhere Ave',
'locality': 'Northcote',
'postal_code': '3070',
'state': 'Victoria',
'state_code': 'VIC',
'country': 'Australia',
'country_code': 'AU'
}

All except the raw field can be omitted. In addition, a raw address may
be set directly:
obj.address = 'Out the back of 1 Somewhere Ave, Northcote, Australia'

Getting Values
When accessed, the address field simply returns an Address object. This way
all components may be accessed naturally through the object. For example::
route = obj.address.route
state_name = obj.address.locality.state.name

Forms
Included is a form field for simplifying address entry. A Google maps
auto-complete is performed in the browser and passed to the view. If
the lookup fails the raw entered value is used.
TODO: Talk about this more.
Partial Example
The model:
from address.models import AddressField

class Person(models.Model):
address = AddressField(on_delete=models.CASCADE)

The form:
from address.forms import AddressField

class PersonForm(forms.Form):
address = AddressField()

The template:
<head>
{{ form.media }} 
</head>
<body>
{{ form }}
</body>

Running Django-Address Tests
Django-address currently has partial form and model test coverage using django.test.TestCase.
To run the current tests:

Clone django-address locally.

Navigate to the example site, . /django-address/example_site

Create a virtual environment and install the example site dependencies. For example:
mkvirtualenv -p python3 django-address
pip install -r requirements.txt

Run ./manage.py test

Important note regarding US Territories
Django-address does not currently support the parsing of US territories aka Protectorates such as Guam or Puerto Rico.
This topic is under active consideration and its status is described in #82
Project Status Notes
This library was created by Luke Hodkinson originally focused on Australian addresses.
In 2015 Luke began working to abstract the project so it could handle a wider variety of international addresses.
This became the current dev branch. While good progress was made on this, the branch became stale and releases
continued under the current model architecture on master.
The project is currently in open development, read more about the project status in this issue.
If you have questions, bug reports or suggestions please create a New Issue for the project.
